*1.
This example is for a SERVOPACK with a three-phase, 200-VAC power supply input. The pin layout of the main
circuit connector depends on the voltage.
*2.
External Regenerative Resistors are not provided by Yaskawa.
*3.
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 connector.
If the power supply is shared, the I/O signals may malfunction.
