Description: Sets the DC braking time (as fault response).
Dependency: Refer to: p1230, p1231, p1232, p1234, r1239
Note: If a speed encoder is being used, DC braking is ended as soon as the drive falls below the standstill threshold
(p1226).
Description: Sets the starting speed for DC braking.
If the actual speed falls below this threshold, then DC braking is activated.
Dependency: Refer to: p1230, p1231, p1232, p1233, r1239
Description: Status word of the DC braking.
Dependency: Refer to: p1231, p1232, p1233, p1234
Note: Re bit 12, 13:
Only effective for p1231 = 14.
Description: Sets the open and closed-loop control mode of a drive.
Value: 0: U/f control with linear characteristic
1: U/f control with linear characteristic and FCC
2: U/f control with parabolic characteristic
3: U/f control with parameterizable characteristic
4: U/f control with linear characteristic and ECO
5: U/f control for drives requiring a precise freq. (e.g. textiles)
