Emotron VS10 - 7 Speed Controller

170 01-6203-01R3, CG Drives & Automation
7.4.5. 7Speed controller
The speed controller is automatically set if one of the following optimisations is carried
out:
 Automatic motor identification (energized)  139
 Automatic motor calibration (non-energized)  140
For typical applications, a manual adaptation of the parameters of the speed
controller is not recommended. A wrong setting may have a negative effect
on the control. For special applications, contact the manufacturer before
adapting the parameters.
Details
The speed controller has an influence in the following motor control types:
• Sensorless control (SL PSM)
• Sensorless vector control (SLVC)
The automatically calculated settings for the speed controller enable an optimal control
behaviour for typical load requirements:
• Minimum speed loss
①
• Minimum settling time
②
• Minimum overshoot
③
Setting notes
If oscillations occur during operation after high load requirements:
• Reduce gain of the speed controller in 0x2900:001 (P332.01).
• Increase reset time of the speed controller in 0x2900:002 (P332.02).
If the speed loss is too high or the settling time too long during operation with high load
requirements:
• Increase gain of the speed controller in 0x2900:001 (P332.01).
If the gain is set too high or the reset time too low, the speed control loop
can become unstable!
