Set the bus voltage level at which
regeneration avoidance operates. When
the bus voltage level is set to low,
DC380V overvoltage error will be less apt to
0.1V 300 to 800V
occur. However, the actual deceleration
/760V*
time increases.
* The initial value differs according to the
voltage level. (200V class / 400V class)
Set sensitivity to detect the bus voltage
1 0 0 to 5 change.
1 (Low) → 5 (High)
Set the limit value of frequency which rises
0 to 10Hz at activation of regeneration avoidance
function.
0.01Hz 6Hz
9999 Frequency limit invalid
Adjust responsiveness at activation of
regeneration avoidance.
A larger setting will improve
0.1% 100% 0 to 200%
responsiveness to the bus voltage change.
However, the output frequency could
become unstable.
Parameters you can use for your own
1 9999 0 to 9999
purposes.
Used for maintenance, management, etc.
by setting a unique number to each inverter
1 9999 0 to 9999
when multiple inverters are used.
