Note – Incremental encoder interface details
Each differential-pair includes a built-in 120
Ω
terminator and the required hardware
circuits to detect a disconnected encoder cable. When a disconnected encoder cable is
detected, the controller will disable the motor. The detection is done on the A and B
channels only (not on the index or Z-channel).
By default, the product does not support single-ended encoder. For use of single-ended
encoder, contact Technical Support.
Note – 5V supply limitation
The 5V supply provided at pin 1 of each ENC connector is internally limited to 0.5A per
connector. The maximum total current provided by all the 5V pins in the product is
limited to 1.5A.
3.4.8 Interfaces A2, B2, C2: Hall Sensors and Static Brake
Connectors A2, B2, and C2 (HALLS), one for each axis, have identical pinouts. Each port provides
3 Hall sensor inputs. In addition, each connector includes 1 RTD input for resistance temperature
detection (typically for motor temperature), and 1 digital output for static braking.
Additional I/Os are available on interfaces A3, B3, C3 (Digital and Analog I/Os), and on interface X4
(General I/Os)
For schematics and more information about these interfaces, refer to the section I/O Interfaces –
