Operation
(1) Wiring Example
Use the brake signal (/BK) and the brake power supply to form a brake ON/OFF circuit. The following dia-
gram shows a standard wiring example.
The timing can be easily set using the brake signal (/BK).
Note: A brake and its power supply are not included.
• Configure the relay circuit to apply th
e holding brake by the emergency stop.
• The brake signal (/BK) cannot be used with
factory settings. The output signal must
be allocated. Refer to (3) Brake Signal (/BK) Allocation to set the parameter Pn50F.
• When using a 24-V brake, separate the 24-VDC power supply from other power sup-
plies, such as the one used for the I/O sign
als of CN1 connectors. Always install the
24-VDC power supply separately. If the power supply is shared, the I/O signals might
malfunction.
