• 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 signals of CN1 connectors. Always install the
24-VDC power supply separately. If the power supply is shared, the I/O signals might
malfunction.
