Characteristic:

Featuring 16-speed equal angle constant moment subdivision, with a maximum resolution of 40000 steps per revolution;

The maximum response frequency can reach 200Kpps;

Automatic half current can be set by users. When the step pulse stops for more than 1.5 seconds, the coil current will automatically decrease to half of the set current;

Optoelectronic isolation signal input/output;

The driving current is adjustable from 1.0A/phase to 4.0A/phase, divided into 8 levels;

Single power input, voltage range: DC20~50V;

Current setting

The operating current of the driver is set by the SW1-SW3 dial, and the operating current is the effective output current for normal operation. The setting switch is detailed in the table below:

Subdivision settings

The subdivision of the driver is set by the SW5-SW8 terminals, with a total of 16 levels. Attached Table: Subtraction (Pulse/Revolution)

Note: Customization of fine scores can be made according to customer requirements

Wiring precautions:

1. The input voltage cannot exceed DC50V;

2. The input control signal level is within the range of+5V~+28V, and there is no need to connect an external current limiting resistor when it is higher than+5V;

3. The falling edge of the input pulse signal is effective;

4. When the temperature of the drive exceeds 80 degrees, the drive stops working and the fault indicator light ALM lights up. Until the temperature of the drive drops to 50 degrees, the drive needs to be powered on again to resume operation. If overheating protection occurs, please install a radiator;

5. The overcurrent (load short circuit) fault indicator light ALM is on. Please check the motor wiring and other short circuit faults. After troubleshooting, it is necessary to power on again to restore;

6. No motor fault indicator light ALM is on. Please check the motor wiring. After troubleshooting, power on again to restore.

Pin Function Description:

Marking symbols	Function Description	Notes
PU+	Input signal photoelectric isolation positive terminal	Connected to the positive end of the signal power supply, the amplitude range is+5V~+28V, which can be driven. When it is higher than+5V, there is no need to connect an external current limiting resistor
PU-	Stepping pulse signal	The falling edge is effective, and every time the pulse changes from low to high, the motor takes one step with an input resistance of 220 Ω                  Requirements: Low level 0-0.5V, high level greater than 4V, pulse width>2.5 μ S
DR+	Input signal photoelectric isolation positive terminal	Connected to the positive end of the signal power supply, the amplitude range is+5V~+28V, which can be driven. When it is higher than+5V, there is no need to connect an external current limiting resistor
DR-	Direction control signal	The falling edge is effective, and every time the pulse changes from low to high, the motor takes one step with an input resistance of 220 Ω                  Requirements: Low level 0-0.5V, high level greater than 4V, pulse width>2.5 μ S
MF+	Input signal photoelectric isolation positive terminal	Connected to the positive end of the signal power supply, the amplitude range is+5V~+28V, which can be driven. When it is higher than+5V, there is no need to connect an external current limiting resistor
