5.6 Function commissioning
Parameter Boost type
P1311 Acceleration boost [%]
P1312 Starting boost [%]
88
Description
This parameter applies boost relative to P0305 (rated motor current) following
a positive 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 (stand-
still).
