The driver adopts circuit similar to servo control, so the motor can run smoothly with little vibration and noise. And the maximum positioning accuracy could reach 40,000 steps/rev.The product is widely used in big and medium-sized CNC equipment with higher resolution, such as engraving machine, medium-sized CNC machine tool, computer-controlled embroidery machine, packing machine, etc. Connected to serial port RX of upper computer (function preservation). Connected to serial port TX of upper computer (function preservation). Connected to serial port ground of upper computer (function preservation). Connected to serial port power of upper computer (function preservation). Can be driven by +5 V-+24 V. DP5 = OFF, PU is step-by-step impulse signal. Falling edge is effective; whenever the impulse drops from high to low, the motor moves one step. Requirements: pulse width> 2.5Î¼S. DP5 = ON, PU is positive step-by-step impulse signal.
Positive terminal of input photoelectric isolation signal. DP5 = OFF, DR is direction control signal. Used to change turning direction of the motor. DP5 = ON, DR is negative step-by-step impulse signal. When it is active (at low level), the motor wiring current is turned off, and the driver stops working; the motor is in a free mode.The driver is ready to output positive photoelectric isolation signal. When the driver is in normal state, ready to receive controller signal, the signal is active (at low level). The driver is ready to output negative photoelectric isolation signal. The working current of the driver is set by DIP-1 terminal, the working current is normal working output current (note: the current is effective current). The micro-step is set by DIP-2 with 16 levels.
The first 4 dip of DIP-2 is for. And the last 2 dip is for function setting.
The attached table: steps (pulse/rev). PU is positive step pulse signal, DR is negative step pulse signal. PU is step pulse signal.
DR is direction control signal. Self-test switch (OFF: receive output pulse ;ON: run at 30rev/min). No light with POW or ALM indicator light.To check if the power supply is normal. To check overcurrent or overheating, motor missing. The motor shaft is locked, the motor cannot operate. To check external control signal. Indicator light shows normal, and the motor shaft is unlocked. To check if MF signal is active. The max speed is set too high. To lower the max speed. The time for speeding up is too short.
To lengthen the time or increase the pulse filtering constant of the driver. The micro-stepping number is not correct. To select the correct micro-stepping number. Excessive load for the motor.
To replace the motor or moderately increase running current of the driver. The driver and motor is not reliably grounded.
To reliably ground the driver and the motor. Severe warming of the driver and the motor. Large running current of the driver or bad external thermal conditions. To moderately reduce driver running current or improve ventilation of the driver and the motor. 1 The input voltage is lower than AC270V.Falling edge is effective of input pulse signal. If you need the rising edge to be effective, please set inner parameter of the driver. When the driver temperature goes beyond 75 degrees, it will halt working, and the fault indicator ALM will be on. Until the temperature drops to 50 degrees, the driver may resume work after a second-time power-on. In case of such overheat protection, please install heat sink. In case of overcurrent (short circuit of load), the fault indicator ALM will be on. Please check motor wiring and other fault of short circuit; after the fault is removed, it will resume upon a second-time power-on.
In case of no motor, the fault indicator ALM will be on. Please check motor wiring; after the fault is removed, it will resume upon a second-time power-on. P2 P3 is set to X-axis for the X-axis pulse. P4 P5 is set to Y-axis, Y axis pulse. P6 P7 is set to Z-axis Z-axis pulse.
The other can be set to A B C axis. A-axis pulse P8 P9 is set as the A axis.P14 is set to B-axis B-axis pulse P1. P16 P17 is set to C-axis, C axis pulse.
Can also be set to the spindle control signal \ electrical permit. Input interface for the P10 P11 P12 P13 P15.Built in DB25 male connector. DB25 Output Pin:P1, P2, P3, P4, P5, P6, P7, P8, P9, P14, P16, P17. DB25 Input Pin: P10, P11, P12, P13, P15. High quality with Surface-mount Tech.
