Inovance MD800 Series - Page 243

Parameter Group
-242-
Description
When the current exceeds the overcurrent stall action current, the overcurrent stall suppression
function is triggered. The output frequency decreases until the current falls below the overcurrent
stall threshold, and then the output frequency increases to the target frequency, which prolongs the
actual acceleration time automatically. A larger parameter value indicates better suppression effect.
F3-21
Compensation coefficient of V/f speed multiplying overcurrent stall action current
Address:
62229
Min.:
50
Unit:
-
Max.: 180 Data type: UInt16
Default:
50
Change:
At stop
Value Range:
50 to 180
Description
This parameter defines the compensation coefficient of V/f speed multiplying overcurrent stall action
current, which can be used to adjust the overcurrent suppression current threshold in the field-
weakening range.
F3-22
V/f overvoltage stall action voltage
Address:
62230
Min.:
330.0
Unit:
V
Max.: 800.0 Data type: UInt16
Default: Single-phase 200 V: 370.0 V;
Three-phase 400 V: 770.0 V
Change:
At stop
Value Range:
330.0 V to 800.0 V
Description
When the bus voltage reaches the value of this parameter, the AC drive starts overvoltage stall
protection.
F3-23
V/f overvoltage stall suppression
Address:
62231
Min.:
0
Unit:
-
Max.: 1 Data type: UInt16
Default:
1
Change:
At stop
Value Range:
0: Disabled
1: Enabled
Description
This parameter defines whether to enable V/f overvoltage stall suppression.
F3-24
Frequency gain for V/f overvoltage stall suppression
Address:
62232
Min.:
0
Unit:
-
Max.: 100 Data type: UInt16
Default:
30
Change:
At once
Value Range:
0 to 100
Description
Increasing F3-24 will improve the bus voltage control effect, but the output frequency will fluctuate. If
the output frequency fluctuates greatly, reduce F3-24 appropriately.
