ACR1200 MOTHERBOARD HARDWARE WIRING
Encoder Inputs (P1), continued.
The ACR1200 can accept any feedback device that supplies either a +5V or +12V
differential signal to the ACR1200. The most common type of device is a differential
encoder. Refer to the table below for common encoder setups.
Encoder Type ACR1200 Pull-
up/Jumper Setting
Length of Cable/Type
Differential Line Driver
(+5 Volt Outputs) Remove Pull-ups 100 ft. (Beldon 9330 Shielded Twisted Pair)
Open Collector Driver
(No Pull-ups on Encoder) Install Pull-ups and
Jumper to +12V 75 ft. (Beldon 9330 Shielded Twisted Pair)
Open Collector Driver
(With Pull-ups to +5 V on Encoder) Install Pull-ups and
Jumper to +5V 50 ft. (Beldon 9330 Shielded Twisted Pair)
TTL Driver
(+5 Volt Outputs) Remove Pull-ups 50 ft. (Beldon 9330 Shielded Twisted Pair)
When using a single-ended encoder (an encoder without the A-, B-, or Z- outputs),
additional pull-ups and pull-down resistors must be added externally to the ACR1200
board in order for the ACR1200 to read the encoder signals. Warning: This is not a
recommended mode of operation. Noise immunity is significantly reduced.
Refer to the ACR1200 Typical Connection Diagram section of this manual for details on
wiring a single-sided encoder to the ACR1200.
