2 Parameters
2.2 List of parameters
Description:
Sets the ramp-down time for the ramp-function generator.
The ramp-function generator ramps-down the speed setpoint from the maximum speed (p1082) down to standstill
(setpoint = 0) in this time.
Further, the ramp-down time is always effective for OFF1.
Dependency:
Refer to: p1082, p1123
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.
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
