*1.
External Regenerative Resistors are not provided by Yaskawa.
*2.
The power supply for the holding brake is not provided by Yaskawa. Select a power supply based on the hold-
ing brake specifications.
If you use a 24-V brake, install a separate power supply for the 24-VDC power supply from other power sup-
plies, such as the one for the I/O signals of the CN1 or CN13 connector. If the power supply is shared, the I/O
signals may malfunction.
