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 minimum ramp-down time.
The ramp-down time (p1121) is limited internally to this minimum value.
The parameter cannot be set shorter than the minimum ramp-up time (p1123).
Dependency:
Refer to: p1082
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.
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.
Rounding off is not active if the technology controller is used as main speed setpoint (p2251 = 0).
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.
Rounding off is not active if the technology controller is used as main speed setpoint (p2251 = 0).
Description:
Sets the smoothed response to the OFF1 command or the reduced setpoint for the extended ramp-function
generator.
Value:
0:
Continuous smoothing
1:
Discontinuous smoothing
Dependency:
No effect up to initial rounding-off time (p1130) > 0 s.
