Inovance MD800 Series - Page 272

Parameter Group
-271-
Description
This parameter defines the gain coefficient of fast speed tracking. It is valid when F6-01 is set to 3. A
larger value indicates faster flying start.
F6-20
Cut-off frequency of fast speed tracking
Address:
62996
Min.:
0.5
Unit:
Hz
Max.: 3.0 Data type: UInt16
Default:
1.1
Change:
At stop
Value Range:
0.5 Hz to 3.0 Hz
Description
This parameter defines the cut-off frequency of fast speed tracking. It is valid when F6-01 is set to 3.
The default value is recommended.
F6-21
Demagnetization time
Address:
62997
Min.:
0.00
Unit:
s
Max.: 10.00 Data type: UInt16
Default:
1.00
Change:
At once
Value Range:
0.00s to 10.00s
Description
In vector control mode, when flying start is enabled (F6-00 = 1), the AC drive cannot be started when
residual magnetism is still present in the motor. The AC drive can be started only after the voltage of
the AC drive has been disconnected for at least the demagnetization time set by F6-21.
F6-22
Start pre-torque setting
Address:
62998
Min.:
0.0
Unit:
%
Max.: 200.0 Data type: UInt16
Default:
0.0
Change:
At once
Value Range:
0.0% to 200.0%
Description
This parameter defines the startup pre-torque setpoint, which can be used to speed up dynamic
response of the motor.
F6-23
Operation at command from power supply unit
Address:
62999
Min.:
0
Unit:
-
Max.: 1 Data type: UInt16
Default:
0
Change:
At stop
Value Range:
0: Stop according to F6-10
1: Ignore stop command
Description
This parameter defines whether the drive unit stops according to the specified mode when receiving a
stop command from the power supply unit.
0: Stop according to the mode set by F6-10 of the drive unit
1: Continue to run, ignoring the stop command sent by the power supply unit
