Info
Selecting how the "Release holding brake" command is to be triggered.
Automatic operation: depending on the device state, the "Release hold-
ing brake" command is given automatically if the controller is to be ena-
bled.
Depending on the TA, the "Release holding brake" command can also be
initiated by the following external triggers:
TA Cia: bit 14
40x6040
TA Speed Control: bit 10
The holding brake is deactivated.
Application time (engagement time) of the holding brake.
• Only effective in automatic operation.
Release time (disengagement time) of the holding brake.
• Only effective in automatic operation.
When 0x2825 = 4 (Manual control mode) and the device state changes
from "switched-on" to "operation enabled", it is detected automatically
whether a holding brake is connected. The brake identification is repea-
ted after every controller enable.
The control logic of the holding brake can be inverted.
Selection of the response for holding brake monitoring.
In the triggered state, the holding brake is monitored cyclically for the
presence of brake current.
After the brake is connected, the establishment of the brake current is
subject to a time delay in accordance with the inductance. Consequently,
there is a slight delay in detecting wire breakage, a terminal short-circuit
or a missing brake supply.
The response set here occurs when monitoring is triggered.
Note:
The brake is not monitored unless it is triggered.
Display of the holding brake status.
• The status is also displayed via bit 14 in the CiA: Statusword 0x6041.
Holding brake is applied.
Holding brake is released.
Setting of the brake opening time when the test signal is transmitted
(Brake control word bit 0 = 1).
Info
By setting a ramp time, a vibration stimulation can be reduced that
might be caused by the brake holding load .
