How to change encoder reading from positive to negative
automationtalk posted a topic in NJ Series / Sysmac Studio
Does anyone know how to change the reading on Omron servo motor reading from negative to positive? The encoder is reading negative values when it is moving in the forward direction. I am using 1S servo on NX1P2 controller on Sysmac studio software. Please suggest. -
Problem: I am getting a control sync fault on 2 recently installed kinetix 5500 but only when my programing PC is connected to the machine network. Install and setup all went great over a 5 day period. Then all of a sudden I started to get this fault. Sometimes 100 times in an hour. As soon as I go offline, and unplug my PC the problem goes away. I have also tried another PC connected to the Machine network and still get the same result. Sometimes machine can run for hours with my PC connected with no problem. I do not have to be online with controller for fault to occur. Setup: I have the 2 K5500's ethernet ports daisy chained together, and then connected via shielded CAT 6 cable directly to port 2 of the Compact Logix Controller Coarse Update is set to 3.5ms and utilization's are at 33% and below.(I have tried the default 2ms with same results) Ethernet modules are configured with FW rev 7.013. Machine network is isolated.(not connected to plant network or internet) Equipment: Compact logix L33ERM Running version 30.01. There are a total of four servos in this system all running over ethernet. 2 Kinetix 350's(not affected), and 2 kinetix 5500's. I have tried: separate ethernet cables for each drive ran through a switch different ethernet cables resetting coarse update speed connecting a different PC for programming I am just not sure where else to go with this. Thanks in advance for any help.

Does any one know any instruction that rotate the 1S Servo Motor continuously with angle(0 to 360) and velocity control ? https://forums.mrplc.com/index.php?/topic/35459-omron-g5-servo-drive-rotary-mode/#comment-165564 Above link may be quite close to what i want. But I have no idea how to set it up Simon

Hi guys! I have several questions connected to kinetix 6000 servo amplifiers. I have a system with AB plc and AB kinetix servo drive. The communication is sercos. Earlier I was worked drives with ethernet communication. I think its better, I could monitor the parmeters durnig as its works. But with the sercos communication I am no longer to be able to do it. One of my question is that like it is possible to check the parameters somehow. I have some problem myabe with the overcurrent recently. But for now I even cant see what is the limit. Is it possible to find it somewhere ? Also when Im watching the parameters in the RSlogix 5000 which is belongs to the servo drive. I can see a row like (servoname)axis fault code and (servoname) axis code. Is there any table where I can see which number belongs to which fault or status? If anyone can help me I just appreciate ahead. Thanks Guys.

I have a test station to test MR-J2S Servo drivers, I am looking for something unique in the drivers to be able to save data about that test. First thought was the SN, but i am not seeing any way to pull serial number from the driver. Only found it on the side of driver and really don't want people having to type it in , cause usually they type in the wrong numbers. Does anyone know of a way to get the serial number out of the driver? or at least where it could be found? Or any other unique identifier in these drivers?

Hello, I am beginner at servo and its driver. i am using MRJ4A driver and HG SR102 servo motor. i want to make my servo stop or alarm when the load is over the maximum load that i set by my self. what parameter should i set to limiting servo load even if the servo motor strength enough to lift the load.?

Hello Everyone Im working with Coordinated Motion instructions, specifically MCLM instruction and I Would like to know if there is a way to know the exact End position (XYZ) when parameter Command Tolerance is Set since i need to calculate the distance to the end point, there is no problem as long no command tolerance is set cause I can find the distance using AB=Sqrt ((x2−x1)**2+(y2−y1)**2+(z2−z1)**2) but as some points have command tolerance the X2,Y2,Z2 are unknown. Hope I was Clear Thank you in Advance.

Hi Everyone. I have been tasked with changing out an older Flex Drive servo drive to a more modern Micro Flex drive in a machine that has an Omron CQM1H-CPU51 PLC. I'm having a few issues but hope that i can gain some clarity around at least one of the hurdles Im facing from here. Biggest issue for me at this moment is My work hasn't yet purchased a programming lead for this PLC (or even the bits required to make one myself) but i have a feeling the control for the Servo is done via motion control in the PLC. Question here is, if changing from one servo drive to another type, will the motion control code need to be updated to work with the new servo drive? I have very limited experience with motion control itself at this stage so I'm a bit lost when it comes to these sort of details. Regards Kiwi_man82

Hi. I am using PLC Q06UDV wit QD77GF to operate 11 servos, it is my first time using QD77GF and CC-Link IE Field. I've done the parameter setting. but the qd77gf error lamp started to blinking. i try to check it in cc link ie field diagnostic and didn't find anything except the error lamp blinking in monitor view. then i checked system diagnostic , no error showing up but, only historical error when i started the power of plc. it show D304 error. in manual book the solution are lengthen the operation cycle qd77gf, check the cable, and shorten plc scan time. where can i find this setting sir?

Hi All, I just start to setup a rotary servo (rotary transmission load type) and the designer pass me the spec of gear ratio 1:100. In my motion scaling page, I set Transmission I:O as 1:100 and then scaling unit is just position unit with 1:1. However, when i jog my rotary servo, it does not reflect the actual position in degree, so I went to read through the manual but still cant quite get how should i configure my scaling so that I can see that when the motor is rotating, i can see it rotate how many degrees? I try to set scaling 360 degree to 1.0 load rev, and the position feedback seems like much more finer....

How can I check output to SERVO motors in ladder logic on GX developer.
Redviper posted a topic in Mitsubishi
Hi everyone, I am new to Mitsubishi PLC. I am trying to see from where Run or speed commands goes to Servo. I have MELSEC FX2M-32MT with FX2N-1PG cards for the Servo and I am using GX Developer 8.91v Also, I would like to mention that initially I found out that BATT V light was lit so here what I didi. >I replaced the battery within 20 second while powered ON. Before changing the battery I took upload of the program successfully. >I have cleared PLC memory and re downloaded the program. > Checked Memory addresses M8005 8006 both are Low. Now, when I am trying to run my machine it is not giving output to two Servos while a conveyor operates when started from the HMI so it means program is inside PLC, right ? Program is attached if someone wants to have a look. labeling mc 300322.rar -
Hello: Does anyone know the details explanation of the Homing Settings for the Axis? Set the homing operation. 0: Proximity reverse turn/home proximity input OFF 1: Proximity reverse turn/home proximity input ON 4: Home proximity input OFF 5: Home proximity input ON 8: Limit input OFF 9: Proximity reverse turn/home input mask distance 11: Limit inputs only 12: Proximity reverse turn/holding time 13: No home proximity input/holding home input Limit Input referring to Input (I/O) ? How about Proximity Input ? It is confusing with the terms. The manual has no explanation for each of the above selection. Any one? Simon

How do i include the fractional part of the position I set for encoder
Jo Palm posted a topic in CX-Programmer
Hi, I need help with my program. How do I include the fractional part of the position I set for encoder? I have an Omron PLC and using cx programmer. I need to command my servo (from HMI number input) to move to a certain position. Now using a manual computation, my servo is supposed to move 95.65mm, however, using my plc program, the resulting position doesn't include the 0.65. I used the FIXL instruction to convert my result from float to 32 bit and it removed the fractional part of the value. Thank you! -
Hi, I have to implement an axis control in a NX1P2 PLC using an inverter (3G3MX2) and an encoder cabled on a EC0122 board. I found something similar implemented on a CJ2M PLC, but I have no idea how to set up the axis in the configuration of sysmac studio and how to implement the control. Can someone help me? Some sample to catch out the configuration? Thanks a lot Andrea

Hey y'all- I have an application that uses an Allen Bradley servo with a brake and a linear actuator to lift a plate vertically. While maintaining a position, the servo drive (Kinetix 5500) will occasionally fault due to over-torque. I'm thinking it could possibly be due to mechanical issues i.e. bearings in the actuator but my initial thought would be that it would fault while moving up/down as well, so far I've only ever seen it fault while holding a position. This leads me to suspect that there may be something off in the control loop. I'm not involved in the setup but I know we use load observer and I reckon we use auto-tune. Other than that, I wonder if it's something to do with the brake. I also read about mechanical resonance in the manual which seems like a stretch but it could be contributing, the frame that the actuator/motor is attached to does vibrate a fair bit. I'm familiar enough with basic motion control using Allen-Bradley and understand the basic concepts behind the servo/control loop. However I'm at a loss for why the servo/drive would spontaneously over-torque while maintaining a position. How would you guys approach troubleshooting this further/solving this issue? Many thanks!

Hi! I would like to do some tuning on our machine, but the problem is that the machine stops and drops origin positions. I selected User Command method with Basic setting. After 5sec I started the tuning, the machine stops with the roblem of that axis. Is there a parameter bit that goes high (or low) during tuning? There're no strange sounds nor movements..even the amplifier doesn't give error code. Is there something else that i should check? In the Servo-Adjustments parameters, One Touch Tuning setting I found the Permissible Overshoot Amount Level is set to 0. Can it be the problem?

Using Virtual servo axis to control 2 real servo axes
PLC Killer posted a topic in NJ Series / Sysmac Studio
Hi there I was reading this thread: And trying to create 3 axes. 1 virtual axis and 2 real axis, I would like to use MC_GearIn for each real axes so both real ones follow the virtual axis (so both can move in sync motion). But my question is: If I give Move cmd(Absolute or relative)to master virtual axis and since it's virtual, it is not going to move then how can the other real ones follow the master(assuming that it's literally electronic gearing). Any help will be appreciated! -

Synchronized Control with Encoder as Master Axis
PLC Killer posted a topic in NJ Series / Sysmac Studio
Hi there This attached pic I got from Omron motion control manual. I am trying to wrap my head around it. Does it mean that the slave servo axis is gonna follow master encoder axis using GearIn FB?? If so, then Can we executive Move FB on encoder axis? Looking forward to your responses. -
Hi Guys, How can I bring an axis into permanent control? that as soon as a value changes, the axis reacts. My Hardware FX5U, FX5SSC MR-JE-20B. Thanks a lot.

Hi. I am planning to do a full scale servo tuning on our producting machine. Is it possible to do it while the servos are in, assambled? I mean no production, no disassembling, servos stay where they are, just tuning them one by one with their empty load..
