Product Introduction

● High performance, low price
● Features 16-step equal-angle constant torque microstepping, with a higher resolution of 20000 pulses/revolution
● Higher response frequency up to 150 Kpps
● When the stepping pulse stops for more than 100ms, the coil current is automatically reduced to half of the set current.
● Optically isolated signal input/output
● Drive current adjustable in 16 steps from 1.2A/phase to 6.0A/phase
● Single power supply input, voltage range: AC 24-80V
● 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
● Pulse smoothing function for smoother motor operation at low speeds, smoothing level is adjustable
● Motor inductance is adjustable to maximize the performance of the stepper motor

Precautions

1. The input voltage must not exceed AC 90V;

2. The input pulse signal is active on the falling edge; for rising edge control, internal driver parameters need to be set;

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

4. If the overcurrent (load short circuit) fault indicator (ALM) lights up, check the motor wiring and other short-circuit faults. After troubleshooting, repower the driver to restore operation;

5. If the no-motor fault indicator (ALM) lights up, check the motor wiring. After troubleshooting, repower 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.
