  2. Hello, I want to ask for a second opinion regarding sizing infeed wires and cables. Take this case for example: 5G16 incoming supply cable (400VAC 3PH+N) to a panel which goes through a MCB and then to a potential distribution block. From there on i can feed various supplies: 1 off 30A Inverter (4mm wire) 1 off 15A Motor (1.5mm wire) 1 off 24VDC PS (2.2A) (1mm wire) The wires from the potential distribution block to the MCP (inverter / motor) an MCCB ( PS)  do they all have to be the same size as the highest consumer? This case inverter so 4mm?   Thank you.

  4. Hi all. I have a Kinetix 350 and an AB TLY servo motor. I'm using the drive's STO function. AC power is supplied into the drive, passing through an "M1" contactor. It makes sense to m e to keep that contactor open, preventing AC power to the drive, until the drive is fully awake.  Is that what you guys do? Someone suggested to me in another forum ( ) that there is no reason not to supply power to the drive right away because the STO function is inhibiting power to the motor anyway. 
  5. What Is Meaning Of Universal Analog Input Card?
  6. Hello, I have a cp1h-y20dt-d (sinking output) plc supposedly to be wired to a servo controller. The pulse control method is Pulse/Direction. I've did some manual research on the PLC and found the following diagram attached Untitled. Since the diagram above doesnt show which terminals does it connect to in the CP1H side circled red, I want to ask if those connections belong to the following diagram attached Untitled1? If so, assuming im planning to use only Pulse Output1 (Pulse/Direction method) from the PLC side, is the connection from the first diagram no.1=CCW0- , no.2=CCW1- , no.3=COM (connected to -ve) *Note: these diagrams are from omron's manual SYSMAC CP Series CP1H-X40D_-_ CP1H-XA40D_-_ CP1H-Y20DT-D CP1H CPU Unit Your replies would greatly help. Thanks and best regards, Summer
  7. I got denied on a job interview, there might have been a few things but I think not knowing NEC and lack of experience with three phase hurt me. The NEC stuff is for another thread but how do you get experience with three phase? Unless you're in a shop already 3ph can be tricky to find. We talked about it at school in multiple classes but never anything hands on. Yet the descriptions for these entry level jobs all expect you to have a few years in of working with 3ph. It looks like I can make my own three phase from 120VAC with a small VFD. Maybe find some small 3ph motor at the scrap yard, get a new contactor and practice taking measurements/hooking stuff up. I've no problem building a trainer if I get to study up on 3ph and NEC at the same time. Crazy? Any advice?
