Description
FRS4-1/2
FRS4-1/2 is a DC powered stepper motor driver designed for 2-phase bipolar stepper motors with encoder feedback.
This device operates on an input supply voltage range of DC 24V to 72V and delivers a maximum output current of 6.0A peak. It uses PWM constant current drive technology and supports communication via RS485 with MODBUS RTU protocol, allowing up to 30 nodes on the bus. The driver features configurable digital inputs and outputs, including pulse, direction, encoder signals, and status LEDs for fault and operation indication. It is suitable for precise location and speed control modes with a compact form factor measuring 156mm by 97mm by 33.5mm.
