Parameter Boost type Description
P1312 Starting boost [%] 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 ... 250.0 (factory default: 0.0)
The voltage boost is only effective when accelerating for the first time
(standstill).
