[PID controller]

The new inverter FR-A840 has a built-in PLC so that training can start it. It is possible to use the built-in PID in the inverter and there is no need PLC  for example inverter FR-D700, FR-E700 and FR-F700 MITSUBISHI.

 

[Programming FX2n-EX]

Hi FranzPLC,

Module FX2N-EX of digital inputs and added to the main unit to the controller. No need to be defined in GX developer.Suffice program is compiled and loaded into the controller.

[Twido Programming cable]

Hi Nuwan,

This cable is not possible. In FX controllers MITSUBISHI using RS422. Upon Twido used RS485.

If you have USB-RS485 converter scheme of colleague ACPI easily you can make cable.

[ADVICE ME]

1. Learning about connecting the input terminals of the inverter - STF, STR, PC or SD
2. Use Does analog inputs - 4 and 5 OR 2 and 5
3. Then define the parameter settings related to input signals

Usually washing a movement forward, backward with low speed and centrifuge at high speed.

[GX Works 3 '..Memory is Insufficient...']

In GX Works3 v.1.020W these bugs are gone.

[Please Help.]

Typically uses port 5001. Check allows this port.

[Running a PID loop on an FR-D700 inverter]

Hello colleague,
 

SP for PID can be set from the control panel or external analog input. With a value of the control panel is used Pr.133. We tune Pr. 79 - 3.

Also be used and parameters Pr.128 - Pr.134 and Pr.575, Pr.576.

Start of PID can use terminal RH set to 14 (Pr.182) or automatic switchover frequency Pr.127.

Good luck.
