Drive installation Install with narrow edges and M4 screws through the holes on both sides. The power device of the driver will generate heat. If it operates continuously under high input voltage and high power conditions, the effective heat dissipation area should be expanded or forced cooling should be applied. Do not use in areas where the air is not circulating or where the ambient temperature exceeds 40 ℃ Do not install the drive in damp or metal shavings.

3.2 Current Setting DIP switch Phase current (peak) Filter setting 3.4 Phase Locked Current Setting SW4=off : (factory default) After the driver stops receiving pulses for about 0.4 seconds, the output current is 50% of the peak value (set to half current, which can reduce the heating of the driver and motor in some applications) SW4=on : The output current of the driver is 90% of the peak value when the motor is stationary. 3.5 Self Tuning Setting SW11=off : Motor power on self setting (factory default) SW11=on : The motor does not self adjust when powered on, and default parameters are...

SW12=on : Under normal working conditions, the alarm output is in a high resistance state (non conductive state). When the driver alarms, the alarm output is in a low resistance state (conductive state). 3.7 Pulse Trigger Edge Setting SW13=off : The rising edge of the pulse is valid (factory default) SW13=on : The pulse falling edge is effective. 3.8 Single and Double Pulse Selection Setting SW14=off : set to single pulse mode (factory default) SW14=on : Set to dual pulse mode. 3.9 Enable Selection Setting SW15=off : When the driver is not enabled, it does not respond to pulses, no current...

Power Supply 4. Power Supply 4.1 Voltage The chopper driver continuously changes the magnitude and direction of the motor winding terminal voltage during operation, while detecting the current to obtain accurate phase current. If both high efficiency and low noise are to be ensured, the driver supply voltage should be at least 5 times the rated phase voltage of the motor (the rated phase current of the motor × Phase resistance). If you need the motor to achieve better high-speed performance, you need to increase the driver supply voltage. If using a regulated power supply, it is required...

Motor Connection When connecting the motor to the drive, please confirm that the power supply to the drive is turned off first. Confirm that the unused motor Caution leads are not shorted to other objects. During the power on period of the driver, the motor cannot be disconnected. Do not connect the motor leads to the ground or power supply. 1) Four-wire motors can only be connected in one way. 2) Six-wire motors can be connected in two ways: full group and half group. In the full group mode, the motor has greater torque at low speeds, but it cannot run as fast as in the half group. When...
