CS-Lab / Re: Motor tunning with CSMIO/IP-A (PID) Trouble with encoders
« on: April 25, 2016, 12:20:47 PM »
Hello all together. I need some help (again). This week i decided to take some brake of work and work a little on my retrofit. I mounted the new glass scale and started to tune the axis. The first thing that bothered me was
that the axis was moving when the csmio-ipa was in emergency stop. Then i figured out that if i set the DAC offset to 0,18 V the motor/axis stays stil. Is this wright ? Or am doing something wrong ?
The next step was i had to figure out the steps per revolution so i gave in the pid tuning some small values and with help of the function axis calibration i got 1234.567901 per unit.
And the max speed was 3000 rpm. The biggest problem is the function auto-tuning in the PID section. I can not get it to work. How long does it take to finis this ? i waited like 10 min and nothing happens ( see my screens on the link at the end of this thread)
Im out of ideas what can i do ? Also how do i know how many Pulses/Rev does my encoder have ? i looked at the manual of my linear scales and i can find the information.
The motors are DC.
