7.5.1 24V Control Circuit Supply
The maximum current that can be drawn from this supply is 500 mA total. Note that if a motor with a brake is
required this may be insufficient current to release the brake, so an external power supply will be required. Any
external power supply must be of the Separated Extra Low Voltage (SELV) type, and approved to IEC 60950.
This 24V control supply is primarily electronically protected with the addition of a self-resetting semi-conductor
fuse. The effects of exceeding the 500 mA limit depend on the magnitude of the overload.
The reference for this 24V control supply is 0VDC (X4 pins 46 & 47). This reference ground must be connected
to the chassis ground (gear tray), to establish a “control ground” for the installation.
7.5.2 Digital Inputs
Digital Input Overview

DI-01
– DI08 are electrically isolated through opto-couplers.

DI-09
– DI10 are not isolated.

Reference 0V is 0VDC (X4 pins 46 & 47)
Refer to the applicable AMD2000 Series Servo Drive - Configuration Guide for detailed information on how to use
ANCA MotionBench to read digital input values.
Application examples for the digital inputs include:

Positive Limit switch

Motor over-temperature

Negative Limit switch

Home switch
