2.3.824V control supply

Depending on model, a 24VDC control supply may be required to provide power to the control electronics when power is removed from the amplifier (see page 2). This is useful for safety where power needs to be removed from the amplifier stage but the control electronics must be powered to retain position and I/O information. The 24VDC supply is connected via X1.

Note: A 24VDC supply is always required for the drive enable input on connector X13.
