Inovance MD800 Series - Page 240

Parameter Group
-239-
0 to 200
Description
A larger overexcitation gain indicates better suppression effect.
When a braking resistor, braking unit, or energy feedback unit is used, set this parameter to 0.
Otherwise, overcurrent may occur during operation.
F3-11
V/f oscillation suppression gain
Address:
62219
Min.:
0
Unit:
-
Max.: 100 Data type: UInt16
Default: Model dependent Change:
At once
Value Range:
0 to 100
Description
A larger oscillation gain indicates better suppression effect.
F3-12
Oscillation suppression gain mode
Address:
62220
Min.:
0
Unit:
-
Max.: 3 Data type: UInt16
Default:
3
Change:
At stop
Value Range:
0: Disabled
3: Enabled
Description
In V/f mode, speed and current oscillation typically occurs when the motor runs at low frequency,
which may lead to overcurrent of the AC drive. In this case, you can enable this function to eliminate
oscillation.
F3-13
Voltage source for V/f separation
Address:
62221
Min.:
0
Unit:
-
Max.: 8 Data type: UInt16
Default:
0
Change:
At once
Value Range:
0: Digital setting (F3-14)
1: AI1
2: AI2
3: AI3
4: Reserved
5: Multi-reference
6: Simple PLC
7: PID
8: Communication
Description
This parameter sets the target voltage in V/f separation mode.
0: Digital setting (F3-14)
The V/f separation voltage is set by F3-14 (voltage digital setting of V/f separation).
1: AI1
The V/f separation voltage is input with current or voltage signals through the AI1 terminal. The
frequency is calculated according to the preset AI curve.
