168 List Manual (LH11), 01/2016, A5E33839529
Description: Sets the signal source for bypassing the ramp generator (ramp-up and ramp-down times = 0).
Caution: If the technology controller is operated in mode p2251 = 0 (technology controller as main speed setpoint), then it is
not permissible to disable the interconnection to its status word (r2349).
Notice: The parameter may be protected as a result of p0922 or p2079 and cannot be changed.
Note: In the case of sensorless vector control, the ramp-function generator must not be bypassed, other than indirectly by
means of interconnection with r2349.
Description: Sets the minimum ramp-up time.
The ramp-up time (p1120) is limited internally to this minimum value.
Dependency: Refer to: p1082
Note: The setting should be based on the startup times (r0345) of the motor.
If the maximum speed p1082 changes, p1123 is re-calculated.
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 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
