9.1 Brake control
VORSICHT
Wrong dimensioning of the brake
Brake does not release or only with delay
a) Choose the input voltage tolerance of the brake corresponding to the tolerance
of the output voltage.
b) Use auxiliary relays if necessary.
Specification brake /relay output
Name
BR+ (X1C.1); BR- (X1C.2)
Function
Output to control one/two brake(s) or relay(s).
Output voltage (DC)
minimum P24Vin – 1.2V
maximum P24Vin
Maximum output current
One brake: 2 A
two brakes: 2 x 1 A
Others
Internal free-wheeling path; internal filter circuit; not
short-circuit proof
Features
• Safely control one brake/relay
• Control two single brakes/relays together (it must be the same brake/relay
twice).
• Internal brake feedback without additional wiring or external via two digital brake
inputs.
• ECO Mode by pulse width modulated control.
• Rapid demagnetization with a counter voltage of 27.5 V (maximum every 5 s).
• Current monitoring
The control, parameterization and reading of the feedback inputs of the brake is
carried out via the integrated safety module. Corresponding wiring and parameter-
ization suggestions are described in the safety manual type 5.
When using the internal supply
• ECO operation of the brake is not recommended.
• the total current consumption of the control card must be observed.
