Product Introduction

● High performance, low price
● Compatible with 2-phase and 3-phase drivers (internal driver parameters need to be set)
● Features 16-step equal-angle constant torque microstepping, with a higher resolution of 60000 pulses/revolution; other microstepping options are available upon request.
● Maximum response frequency up to 200Kpps
● When the stepping pulse stops for more than 100ms, the coil current automatically reduces to half of the set current.
● Drive current adjustable in 16 steps from 1.2A/phase to 6.0A/phase
● Single power supply input, voltage range: DC24-80V
● Power-off phase memory function (the system automatically memorizes the phase when the device is powered off due to accidental or human reasons)
● I/O signals: all input signals are optically isolated, signal level compatible with 5-24V levels
● Pulse smoothing function for smoother motor operation at low speeds; smoothing level is adjustable
● Adjustable motor inductance to maximize the performance of the stepper motor

Precautions

1. The input voltage must not exceed DC 80V;

2. The input control signal level is 5-24V. When the host device uses 24V level, connecting a 1K resistor in series helps improve anti-interference capability;

3. The input pulse signal is active on the falling edge. For rising edge control, internal driver parameters need to be configured;

4. When the driver temperature exceeds 75°C, the driver stops working and the fault indicator ALM lights up. The driver must be powered on again to resume operation after the temperature drops to 50°C. If overheating protection is triggered, please install a heat sink;

5. If the overcurrent (load short-circuit) fault indicator ALM lights up, please check motor wiring and other short-circuit issues. After resolving the problem, power cycle the driver to restore operation;

6. If the no-motor fault indicator ALM lights up, please check motor wiring. After resolving the issue, power cycle the driver to restore operation.

Self-test

Note: 1. When D6 is ON, the self-test switch is OFF.
2. When D6 is OFF, the self-test switch is ON.
