Appendix K PowerFlex 525 Synchronous Reluctance Motor Configuration
SynRM Control
Configuration
To run the motor test, make sure you have installed the PowerFlex 525 drive
firmware revision 7.001 or later. For instructions, see Download Files
on
page 10.
Select the Control Mode:
Set P039 [Torque Perf Mode] = 5 “SynRm”
Increase the bandwidth to obtain
faster speed response. If oscillation
occurs, decrease the bandwidth.
No SynRM parameters
Is the motor
auto-tuning
successful?
Check the following motor parameters:
A501 [PM IR Voltage]
A502 [PM IXd Voltage]
A503 [PM IXq Voltage]
A504 [PM BEMF Voltage]
Start
Set the motor parameters setting:
Rated Voltage: P031 [Motor NP Volts]
Rated Frequency: P032 [Motor NP Hertz]
OL Current: P033 [Motor OL Current]
Rated Current: P034 [Motor NP FLA]
Pole Numbers: P034 [Motor NP Poles]
Rated RPM: P036 [Motor NP RMP]
Rated Power: P037 [Motor NP Power]
Minimum Frequency: P043 [Minimum Freq]
Maximum Frequency: P044 [Maximum Freq]
Set A484 [Current Limit 1]
recommended value: > 1.65 x Rated Motor Current
Motor Parameter Auto-Tuning:
Set P040 [Autotune] = 1 “Auto Tune”
Press Run
No-Load Run
