Setup: All setups Conversion index: -1
Data type: Uint16 Change during operation: True
This parameter enables high starting torque. This function ignores current limit and torque limit during start of the motor. The time from
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 motoric torque limit are set to the maximum possible value for the drive/motor combination. The time without protection from the
current limit and torque limit must not exceed the value set in parameter 1-79 Compressor Start Max Time to Trip. Otherwise, the drive
trips with alarm 18, Start Failed.
1-79 Compressor Start Max Time to Trip
Default value: 5.0 s Parameter type: Range (0.0–10.0 s)
Setup: All setups Conversion index: -1
Data type: Uint8 Change during operation: True
The time from the start signal is given until the speed exceeds the speed set in parameter 1-78 Compressor Start Max Speed [Hz] must
not exceed the time set in this parameter. Otherwise, the drive trips with alarm 18, Start Failed. Any time set in parameter 1-71 Start
Delay for use of a start function must be executed within the time limit.
4.2.9 1-8* Stop Adjustments
Parameters for adjusting motor stop settings.
1-80 Function at Stop
Default value: [0] Coast Parameter type: Option
Setup: All setups Conversion index: –
Data type: Uint8 Change during operation: True
Select the drive function after a stop command or after the speed is ramped down to the settings in parameter 1-82 Min Speed for
Function at Stop [Hz]. Available selections depend on the setting in parameter 1-10 Motor Construction.
