Function

Dual-axis servo control: Supports 2-axis open-loop or closed-loop motion control, suitable for drivers/actuators that require ±10V speed or torque reference.

SSI feedback support: It provides synchronous serial interface (SSI) feedback with a resolution of 8 to 31 bits, supports binary or Gray code sensors, and ensures high-precision position feedback.

Advanced control algorithm

Position loop: PID with speed feedforward.

Velocity loop: PI with acceleration feedforward, supporting directional scaling and friction compensation.

Position and speed/hydraulic combined control, suitable for hydraulic drive or speed control applications.

Flexible input/output:

Analog output (±10V) is used for speed or torque control.

Registration input, origin limit switch and driver fault input support rapid event detection.

The driver enables output for direct control of the servo driver.

Modular integration: It can be installed on a ControlLogix rack and work in conjunction with processor modules (such as 1756-L55), supporting multi-module configuration (up to 16 modules per controller).

Diagnosis and Monitoring: It provides LED indicator lights (OK, servo status, input/output status), supporting real-time fault diagnosis and status monitoring.

Programming support: Configured through Studio 5000 Logix Designer or RSLogix 5000, motion instructions (such as MAJ, MAM) are supported.
