Product Description

The ACR222/2 (Part Number: 00012285-10) is a dual-axis stepper motor control module for the Bachmann M1 automation system, providing high-speed pulse outputs and 24-bit encoder feedback. It supports independent or synchronized axis control for precision positioning in lab automation, packaging, and solar tracking applications.

The module features selectable encoder supply (+5 V / +15 V) and high-frequency stepper outputs up to 150 kHz, with programmable acceleration and braking ramps from 8 ms to 131 s.

FAQ

How do I switch encoder power between 5V and 15V?
Via internal hardware jumpers. Set before installation to match your encoder.

Can this module control servo drives?
Optimized for stepper Step/Direction interfaces. For analog or bus-controlled servos, use an M1 AMC series axis module instead.
