Parameter
List of parameters
p1233[0...n] DC braking time / DCBRK time
SERVO_S110-CAN, Can be changed: U, T
SERVO_S110-DP,
Data type: FloatingPoint32
SERVO_S110-PN
P-Group: Functions
Not for motor type: PEM, REL, FEM
Min
0.0 [s]
Description: Sets the DC braking time (as fault response).
Dependency: Refer to: p1230, p1231, p1232, p1234, r1239
Note: The time set is also effective when parameterizing DC braking as fault response.
If a speed encoder is being used, DC braking is ended as soon as the drive falls below the standstill threshold
(p1226).
p1234[0...n] Speed at the start of DC braking / DCBRK n_start
SERVO_S110-CAN, Can be changed: U, T
SERVO_S110-DP,
Data type: FloatingPoint32
SERVO_S110-PN
P-Group: Functions
Not for motor type: PEM, REL, FEM
Min
0.00 [rpm]
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
Caution: If an encoder fault occurs during closed-loop operation with an encoder, controlled deceleration of the drive down to
the start speed p1234 can no longer take place. In this case, DC braking is activated immediately and injects the
braking current p1232 for the braking time p1233 after de-magnetizing. The braking current and braking duration
must, therefore, be dimensioned accordingly for this situation so that the drive can be decelerated to standstill.
In the case of operation with an encoder, this speed may not be set too low so as ensure that the oscillation move-
ment induced by the residual flux/remanence of the motor does not cause DC braking to be de-activated again.
p1235[0...n] BI: External armature short-circuit, contactor feedback signal / ASC ext feedback
SERVO_S110-CAN, Can be changed: T
SERVO_S110-DP,
Data type: Unsigned32 / Binary
SERVO_S110-PN
P-Group: Functions
Not for motor type: -
Min
-
Description: Sets the signal source for the contactor feedback signal for external armature short-circuit.
Dependency: Refer to: p1230, p1231, p1236, p1237, r1239
Notice: In order that the pulses are not enabled when the contactor is closed, the contactor feedback signal must lag by a
sufficiently long time when opening the contactor.
Note: 1 signal: The contactor is closed.
0 signal: The contactor is open.
p1236[0...n] Ext. armature short-cct., contactor feedback signal monit. time / ASC ext t_monit
SERVO_S110-CAN, Can be changed: U, T
SERVO_S110-DP,
Data type: FloatingPoint32
SERVO_S110-PN
P-Group: Functions
Not for motor type: -
Min
0 [ms]
Description: Sets the monitoring time of the contactor feedback signal for the external armature short-circuit configuration.
