2.2 List of parameters
Note: For U/f control and sensorless vector control (see p1300), a ramp-down time of 0 s does not make sense. The setting
should be based on the startup times (r0345) of the motor.
If the maximum speed p1082 changes, p1127 is re-calculated.
If a braking resistor is connected to the DC link (p0219 > 0), then the minimum ramp-down time is automatically
adapted using p1127.
Description: Sets the initial rounding-off time for the extended ramp generator. The value applies to ramp-up and ramp-down.
Note: Rounding-off times avoid an abrupt response and prevent damage to the mechanical system.
Description: Sets the initial rounding-off time for the extended ramp generator. The value applies to ramp-up and ramp-down.
Note: Rounding-off times avoid an abrupt response and prevent damage to the mechanical system.
Description: Sets the final rounding-off time for the extended ramp generator.
The value applies to ramp-up and ramp-down.
Note: Rounding-off times avoid an abrupt response and prevent damage to the mechanical system.
Description: Sets the final rounding-off time for the extended ramp generator.
The value applies to ramp-up and ramp-down.
Note: Rounding-off times avoid an abrupt response and prevent damage to the mechanical system.
Description: Sets the smoothed response to the OFF1 command or the reduced setpoint for the extended ramp-function
generator.
Value: 0: Cont smoothing
1: Discont smoothing
