Fault definition
875
Fault definition
10
0
At occurrence of any fault, output is shut off
immediately. At this time, the fault output also turns
on.
1
At occurrence of external thermal operation (OHT),
electronic thermal relay function (THM) or PTC
thermistor function (PTC) fault, the motor is
decelerated to a stop.
At occurrence of fault other than OHT, THM and
PTC, trips immediately. Same operation as when "0"
is set is performed under position control.

*
300 to 800V
Set the bus voltage level at which regeneration
avoidance operates. When the bus voltage level is
set to low, overvoltage error will be less apt to occur.
However, the actual deceleration time increases.
The set value must be higher than the power supply
voltage
×
* The initial value differs according to the voltage level.

Set the limit value of frequency which rises at
activation of regeneration avoidance function.

Regeneration avoidance
voltage gain
0.1% 100% 0 to 200%
Adjust responsiveness at activation of regeneration
avoidance. Setting a larger value in Pr.886 will
improve responsiveness to the bus voltage change.
However, the output frequency could become
unstable. When vibration is not suppressed by
decreasing the Pr.886 setting, set a smaller value in
Pr.665.
