S-DIAS Stepper Motor Output Stage Brake Chopper Specifications Maximum current with 1 stepper motor output stage 50 V/5 A 1 brake chopper 1 incremental encoder input RS485/TTL 2 enable inputs with STO function 2 latch/digital inputs The S-DIAS stepper motor output stage allows the connection of 2-phase stepper motors with a phase current up to 5 A. The incremental encoder input, which supports RS422 as well as TTL encoders, is pro-vided for position feedback. With both enable inputs, the safety function STO is implemented. The 2 latch/digital inputs are provided for the reference motion and monitoring the end positions.
