Chapter 11 Description of Parameter Settings
|
C200 Series
11-102
In PG control mode, the AC motor drive will execute the speed search function automatically by
the PG speed when this setting isn’t set to 0.
Maximum Power Loss Duration
Factory Setting: 2.0
Settings 0.1~20.0 sec
If the duration of a power loss is less than this parameter setting, the AC motor drive will resume
operation. If it exceeds the Maximum Allowable Power Loss Time, the AC motor drive output is
then turned off (coast stop).
The selected operation after power loss in Pr.07-06 is only executed when the maximum
allowable power loss time is
≤
5 seconds and the AC motor drive displays “LU”.
But if the AC motor drive is powered off due to overload, even if the maximum allowable power
loss time is
≤
5 seconds, the operation mode as set in Pr.07-06 is not executed. In that case it
starts up normally.
Base block Time
Factory Setting: 0.5
Settings 0.1~5.0 sec
When momentary power loss is detected, the AC drive will block its output and then wait for a
specified period of time (determined by Pr.07-08, called Base-Block Time) before resuming
operation. This parameter should be set at a value to ensure that any residual regeneration
voltage from the motor on the output has disappeared before the drive is activated again.
