Product information
Overview
Applications
- Servo-motor positioning: 3-channel positioning with servo motors.
- Stepper-motor positioning: 3-channel positioning with stepper motors.
Key Features
- 3-channel positioning: Function module for positioning with servo and stepper motors.
- Digital I/O capacity: 6 configurable digital inputs and 4 configurable digital outputs for each channel/axis.
- Encoder interfaces: Supports incremental Encoder (symmetrical) and absolute Encoder (SSI) signals with 5 V difference signals (phys. RS 422).
- Supply voltage: Rated auxiliary and load voltage is 24 V DC; the permissible range is 20.4 V to 28.8 V, with dynamic limits of 18.5 V and 30.2 V.
- Stepper drive performance: Pulse frequency is 200 kHz; 500 kHz available soon. The shielded cable length is maximum 35 m with symmetrical transmission and 10 m with asymmetrical transmission.
- Front connection and protection: Requires 1x 48-pin front connector. Digital inputs and outputs have potential separation by Optocoupler, and the digital outputs have short-circuit protection.
