Description

The DQ2722MA is a full digital 2 phase stepper driver based on DSP control and can supply 7A RMS ( 9.8A Peak)

The DQ2522MA is a full digital 2 phase stepper driver based on DSP control and can supply 5A RMS ( 7.0A Peak)

The drive voltage is from 110V to 220VAC - no external PSU required. It is designed for use with the 2 phase hybrid stepper motor with 86mm to 130mm outside diameter.

Features

  • 16 channels constant angle, constant torque micro steps, highest micro step: 40000ppr
  • Highest response frequency: 200Kpps
  • Current of winding will be reduced by approximately 50% when no step pulse command is received for 0.1 second
  • Opto-isolated signal I/O
  • Drive current is adjustable in 16 channels from 1.2A/phase to 7.0A/phase ( DQ2722MA )
  • Drive current is adjustable in 16 channels from 0.5A/phase to 5.0A/phase ( DQ2522MA )
  • Single power supply from 110V to 220VAC
  • Phase terminal memory function (motor phase terminal is memorized after input pulse train stopping 5s and it is recovered when stepper driver power on or signal MF changes from low level to high level)
