Constant-Torque Industrial Closed-Loop Stepper Driver [M4]

Built-in voltage-boost compensation circuit and algorithm maintains constant torque during operation. Driver supply voltage DC 6–40 VDC; 12/24/36 V recommended. At 12 VDC input the internal voltage boosts to 32 V; at 24 VDC, to 36 V; at 36 VDC, to 44 V. Additionally, when the output current is set below 2 A (peak), the driver can start from 6 VDC, boosting internally to 28 V.

Built-in back-EMF absorption circuit and algorithm dissipates the back-EMF generated during motor operation

Built-in brake control, alarm signal output, etc.

DIP switches select pulse control,internal IO pulse control

Brand-new 32-bit DSP technology, ultra-low vibration and noise

Reverse-polarity protection: reversed voltage will not damage the driver

Compatible closed-loop motor frames: frames 20/28/35/39/42/57/60 full range of closed-loop motors

Current output adapts to load changes Maximum continuous output current 6.0A

Accepts differential and single-ended pulse/direction/free commands

Maximum pulse frequency up to 500 kHz (factory default 200 kHz)

Pulses per revolution (microstep) set via debug software or DIP switches

Pulse, direction and free input signal level: 5–24 V compatible,interfaces accepting only 5 V signals available on request

Over-voltage, under-voltage, over-current, encoder-deviation and torque protection

Adopts FOC field-oriented control and space vector PWM (SVPWM) closed-loop control

With Mini-USB8 serial TTL (RS232 Modbus) debugging with our dedicated cable and software; fully isolated RS485 control circuit reserved

Default encoder resolution: 1000 PPR; 400/2500/5000 PPR or other resolutions settable via serial port

The encoder input accepts differential signals; for single-ended encoder signals please inform us in advance
