Appendix K PowerFlex 525 Synchronous Reluctance Motor Configuration
Startup with Load adjustment procedure
Frequency command setting
higher than A590 [SYNRM SW Freq]
High-frequency loading
performance test
Is the
speed stable and
does not oscillate before
A590 [SYNRM SW Freq]?
Load operation test
Motor starts running
Finish
Yes
No
1. Adjust the ASR Bandwidth
2. Adjust the A593 [SYNRM Freq1 Kp]
Transient load
: If the speed drops
drastically, increase the setting to
improve the response.
Steady-state load
: If there is extreme
frequency vibration, decrease the setting.
Did the high-frequency
loading performance
meet the request?
No
Insufficient high-frequency
loading performance
1. When the motor increases the load at low
frequency, the speed drop is too large
2. Output frequency low frequency flutters
1. Adjust A595 [SYNRM Freq2 BW]
2. Adjust A596 [SYNRM Freq2 Kp]
3. Adjust ASR Bandwidth
Yes
