2.4 IO interface
Connect "brake output (TB2)" and "emergency stop input (TB3)" in the following way.
2.4.1 Wiring of brake output (TB2)
The BK+ and BK- terminals indicate brake output terminals (rated current: Max. 150mA).
To use the electromagnetic brake, a 24VDC external power supply is necessary.
To connect above-mentioned induction loads such as the relay to the external contact, use
ones with a rated coil voltage of 24VDC and a rated current within 100mA, and take a surge
suppression measure.
Perform wiring of the electromagnetic brake so that the brake is released when the current
flows across BK+ and BK-, and it is applied when the current is stopped, without relations to
the negative or positive activation.
The cable sheath peeling length should be 9 or 10mm.
The applicable cable is AWG22 to 24 (single cable) or AWG22 to 24 (stranded cable).
