1)
If there is a "suspended load" and at least a speed-controlled operating mode, the torque required to hold the
load is built up AFTER the brake is enabled by the control deviation
2)
The torque required to hold a load is built up BEFORE the brake is enabled. If the parameters for the holding
torque are correctly set, the load therefore sags significantly less after the brake is enabled than in

134.4
Command
Command to the motor holding brake
In the triggering mode (
"Automatic"), 134.4 Bit 0 of the device control state ma-
chine is activated. However, if the brake is to be triggered in the "Automatic" mode for ser-
vice purposes by writing directly to 134.4 Bit 0, 134.4 Bit 1 must be set. After the service
mode is switched off, the brake remains in its current state, i.e., the original state before
the service mode was activated is not re-established.
If the motor holding brake is to be actuated manually (
"Manual"), the command
must be transmitted to the brake directly via 134.4.
134.5
Torque limit
Torque limit for torque-controlled enabling of the motor holding brake in the Automatic
mode (
Bit 0 = 1). This torque is built up before the brake is enabled if the appro-
priate mode is selected (
Bit 0 = 1).
2
Applying the brake while pulses are inhibited (i.e. pulses are already inhib-
ited when the brake is to be applied):
0: Brake is applied immediately while pulses are inhibited
1: Brake is applied while pulses are inhibited as soon as the magnitude of
the actual speed has fallen below the speed limit (
).
