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.

Current setting Subdivision setting Operating Mode Self test 3.1 Subdivision Setting DIP switch Pulse count / Revolution Operation mode Double pulse Pulse+Direction Mode : Pulse is added to the pulse input end. When the optocoupler at the direction input end is not connected, the motor rotates in one direction, and when the optocoupler at the direction input end is connected, the motor rotates in the other direction Dual Pulse Mode : When the pulse input terminal is pulsed, the motor rotates in one direction, and when the direction input terminal is pulsed, the motor rotates in the other...

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...

Motor Connection / Signal Input 1) The corresponding colors of different motors are different. When using the motors, the specifications of the motors shall prevail. 2) The phases are relative, but the windings of different phases cannot be connected to the terminals of the same phase of the driver (A +, A- is one phase, B +, B- is the other phase). If the motor direction is different from the expected direction, only A + , A-. 3) This driver can only drive two-phase hybrid stepping motors, not three-phase and five-phase stepping motors. 6. Signal Input 6.1 Pulse Signal : PUL Can accept...

Signal Input 6.3 Pulse / Direction Input Timing Diagram Input signal waveform and timing (single pulse method) Input signal waveform and timing (double pulse method) PUL Input port (Forword rotation) DIR Input port (Reverse) Can accept 5VDC single ended or differential signals. When the built-in optocoupler is turned on, the motor phase current is cut off and the rotor is in a free state (offline state). When this function is not needed, the offline signal end can be suspended.

Typical Signal Connection Method Typical Connection Method for Signal Output Relay Connection When the relay is connected, it is required to connect diodes at both ends of the relay (such as IN4000 series) Optocoupler Connection The alarm output is photoelectric isolation, with a maximum withstand voltage of 30VDC and a maximum saturation current of 50mA. When the driver is working properly, the output is closed. When the driver makes an error, the output is suspended.

Wiring Requirements In order to prevent the driver from being disturbed, it is recommended to use shielded cable for the control signal, and the shield layer should be shorted to the ground. Except for special requirements, the shielded wire of the control signal cable is grounded at one end: the upper end of the shielded cable is grounded The driver end of the wire is left floating. Grounding can only be performed at the same point in the same machine. If it is not a real ground wire, the interference may be serious, and the shielding layer is not connected at this time. Pulse and...
