Description
Determines whether the V/f overcurrent stall function is enabled.
F3-20
V/f overcurrent stall suppression gain
Address:
0xF314
Min.:
0
Unit:
‑
Max.: 100 Data type: UInt16
Default:
20
Change: In real time
Value Range:
0–100
Description
When the current exceeds the overcurrent stall action current, the overcurrent
stall suppression function is triggered, and the output frequency decreases. When
the current falls below the overcurrent stall threshold, the output frequency
increases to the target frequency, and the actual acceleration time prolongs
automatically. A larger parameter value indicates better suppression effect.
F3-21
Action current compensation coefficient for V/f speed multiplying
overcurrent stall
Address:
0xF315
Min.:
50
Unit:
‑
Max.: 200 Data type: UInt16
Default:
50
Change:
At stop
Value Range:
50 to 200
Description
This parameter reduces the overcurrent stall action current at high speed. It is
invalid when set to 50%. The recommended value for F3‑18 in the flux weakening
area is 100%.
F3-22
Overvoltage stall action voltage in V/f mode
Address:
0xF316
Min.:
200
Unit:
V
Max.: 2000 Data type: UInt16
Default:
770
Change:
At stop
Value Range:
200.0 V to 2000.0 V
Description
When the bus voltage reaches the value of this parameter, the AC drive starts
overvoltage stall protection.
