P 5.6.7 Start Max Speed [Hz]
Use this parameter to enable high starting torque. The time from the moment the start signal is given, until the speed exceeds the speed
set in this parameter, becomes a start zone. In the start zone, the current limit and motor torque limit are set to the maximum possible
value for the frequency converter-motor combination. Setting the parameter value to zero disables the function.
Default value: 0.0 Parameter type: Range (0.0–500.00)
Parameter
number:
178 Unit: Hz
Data type: uint16 Access type: Read/Write
P 5.6.8 Start Max Time to Trip
Use this parameter to define the maximum start time. The time from the moment the start signal is given until the speed exceeds the
speed set in 5.6.7 Start Max Speed [Hz] must not exceed the time set in this parameter. Otherwise, the frequency converter stops with
fault 18, Start Failed.
Default value: 5.0 Parameter type: Range (0.0–10.0)
Parameter
number:
179 Unit: s
Data type: uint8 Access type: Read/Write
P 5.6.11 Sync. Motor Start Mode
Use this parameter to select the motor start-up mode. This is done to initialize the VVC+ control core for a previously free-running motor.
This parameter is active for motors in VVC+ only if the motor is stopped (or running at low speed).
Default value: 0 [Rotor Detection] Parameter type: Selection
