For axes, which must be secured against undesirable motion when po-
wered down, the brake sequence control of "SIMODRIVE 611 univer-
sal" can be used to control the motor holding brake.
The relay for the motor holding brake is controlled via a freely–parame-
terizable output terminal.
SIEMENS motors are optionally available with a motor holding brake.
Warning
It is not permissible to use the motor holding brake as working brake,
as it is generally only designed for a limited number of emergency
braking operations.
The brake sequence control is activated by setting P0850 to 1.
This function is possible either the n–set mode or pos mode.
The brake sequence control operates with the "open holding brake"
output signal. The signal can be output as follows:
S
Using a freely–parameterizable output terminal
The required output signal for the control board or the optional TER-
MINAL module must therefore be assigned function No. 35 for the
motor holding brake by appropriately parameterizing it.
Output terminals on the control board
0.x, O1.x, O2.x and O3.x
Output terminals for the optional TERMINAL module
O2, O3 to O11
P0699 can be used, for each output terminal, to set whether the sig-
nal is output inverted.
The relay for the motor holding brake is connected at the parame-
terized output terminal.
S
Via status signal for PROFIBUS–DP
The DP master must process the "open holding brake" status signal.
The signal must be connected to the digital output of the master, to
which the relay for the motor holding brake is connected.
