Note: For U/f control and sensorless vector control (see p1300), ramp-down times of 0 s are not recommended. The set-
ting should be based on the startup times (r0345) of the motor.
If the maximum speed p1082 changes, p1127 is re-calculated.
Description: Sets the minimum ramp-down time.
The ramp-down time (p1121) is limited internally to this minimum value.
Dependency: Refer to: p1082
Note: For U/f control and sensorless vector control (see p1300), ramp-down times of 0 s are not recommended. The set-
ting 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.
