Parameters
Parameter Function
Switch-on delay Required time to complete opening of the brake with:
– Setting of the controller enable (DIN5 0 } 1)
– START signal (if the automatic brake is activated) and the start
of a positioning motion.
The configured brake output is set immediately; the brake opens.
Correct setting ensures that the drive does not run against the
closed brake. With a START signal before the switch-on delay
expires, the motor controller starts the positioning motion only
after the switch-on delay has expired completely.
Switch-off delay Required time until complete closing of the brake with:
– Removal of controller enable (DIN5 1
}
0)
– Expiration of the activation time of the automatic brake.
Correct setting ensures that the drive is maintained in the current
position until the holding brake has achieved its full holding
torque. The controller is only switched off after the switch-off delay
has expired.
Activation time of the automatic
brake
Time in [ms] between the completion of a positioning motion
(“Motion complete”) and the resetting of the brake output
(providing in this period of time there is no new START signal). The
switch-off delay follows after the activation time.
Value = 0 deactivates the automatic brake.

6.7.3 Position trigger
The position triggers can be used to pass on information about the logical statuses of position
switches, rotor position switches and cam controller units (only when the cam disc function is activ-
ated) to digital outputs. Four position triggers can be configured to this end.
With specified trigger levels, the position triggers can:
– implement the actual position of the commutation encoder corresponding to the value pair (switch)
in binary signals (1/0)
– output the binary signals logically linked with OR to the assigned digital outputs.
A maximum of four value pairs for positions or four value pairs for rotor locations must be assigned to
each position trigger. To depict the information on a digital output, the function of a digital output must
be set to “position trigger 1” … “4”.
