HOW TO DO SIMCNC PID TUNNING ?

#1 · 11 March 2025, 06:03

Hello, I am currently working on a CNC electrical device with the following.
Software: SIMCNC
Controller: CSMIO/IP-A - ANALOG +-10V

Servo system: PANASONIC A4-SERIES SPEED MODE

I managed to somehow control the servo for the X-axis and Y-axis, but the Z-axis is not tuned as shown in the attached picture.

Please tell me more specifically the order of manual tuning during PID tuning(?) or the method. For example, fixing some values such as KP KI and changing some values, etc.
Thank you.

I am currently trying to input random numbers for KP KI, etc., but I can't see any sign of it being resolved.
Ah~ I have already checked the physical part (wiring, encoder signal reception, +-10V output, etc.) and there is no problem.

The message you sent a photo of says that the drive does not reach the speed set by the CSMIO/IP-A controller
The reason for this may be the untuned speed loop of your drive.

As for pid tuning, you can use autotuning or refer to the instructions for Mach4

This instruction is also suitable for simCNC.
