Range Description
Traverse function invalid
0
Traverse function is valid only in the
1
external operation mode
Traverse function is valid independently
2
of operation mode
Amplitude amount during traverse
0 to 25%
operation
Compensation amount at the time of
0 to 50% amplitude inversion
(acceleration → deceleration)
Compensation amount during
amplitude inversion operation
0 to 50%
(deceleration → acceleration)
Acceleration time during traverse
0.1 to 3600s
operation
Deceleration time during traverse
0.1 to 3600s
operation
0 Regeneration avoidance function invalid
Regeneration avoidance function is
1
always valid
Regeneration avoidance function is valid
2
only during a constant speed operation
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.
Set sensitivity to detect the bus voltage
0 to 5 change.
1 (Low) → 5 (High)
Set the limit value of frequency which
0 to 10Hz rises at activation of regeneration
avoidance function.
9999 Frequency limit invalid
Adjust responsiveness at activation of
regeneration avoidance.
0 to 200% A larger setting will improve responsiveness
to the bus voltage change. However, the
output frequency could become unstable.
Parameters you can use for your own
0 to 9999
purposes.
Used for maintenance, management, etc.
0 to 9999
by setting a unique number to each
inverter when multiple inverters are used.
