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.

BI: Bypass ramp-function generator / Bypass RFG
Access level: 4
Calculated: -
Data type: Unsigned32 / Binary
Can be changed: T, U
Scaling: -
Dynamic index: CDS, p0170
Unit group: -
Unit selection: -
Function diagram: 2505
Min:

Max:
-
Factory setting:
0
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), or the
"hibernation mode" function is activated, then it is not permissible to disable the interconnection to the relevant status
word (r2349, r2399).
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 or r2399.

Ramp-function generator minimum ramp-up time / RFG t_RU min
Access level: 4
Calculated: CALC_MOD_ALL Data type: FloatingPoint32

Min:
0.000 [s]
Max:
999999.000 [s]
Factory setting:
0.000 [s]
Description:
Sets the minimum ramp-up time.
The ramp-up time (p1120) is limited internally to this minimum value.
Dependency:
See also: 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).
