Description
This parameter applies boost relative to P0305 (rated motor current) following a posi-
tive setpoint change and drops back out once the setpoint is reached.
Range: 0.0 to 250.0 (factory default: 0.0)
The voltage boost is only effective when accelerating or braking.
This parameter applies a constant linear offset relative to P0305 (rated motor current)
to active V/f curve (either linear or quadratic) after an ON command and is active until:
ramp output reaches setpoint for the first time respectively
•
setpoint is reduced to less than present ramp output
•
Range: 0.0 to 250.0 (factory default: 0.0)
The voltage boost is only effective when accelerating for the first time (standstill).
