Two-phase hybrid stepping motor dynamic voltage 12 to 48V, the current is less than 5A outer diameter of 35 to 86 mm. This drive using the drive's current loop subdivision control, the motor torque ripple is very small, low-speed running is very smooth, almost no vibration and noise. High-speed torque is much higher than other two-phase drive, high positioning accuracy. Widely used in the engraving machine, CNC machine tools, packaging machinery and other high resolution requirements on the device.

Control signal interface
- Figure 1 is a wiring schematic of the drive
- 1, the definition of control signals
PUL +: step pulse signal is input side or the positive pulse signal input positive terminal
PUL-: the negative input of the negative input pulse signal or a positive pulse signal
DIR +: stepping direction signal input to the positive terminal or negative pulse signal input to the positive terminal
DIR -: stepping direction signal input of the negative side or reverse step pulse signal input negative terminal
EN +: offline can reset signal input side is
EN-: offline can reset signal input negative terminal
Offline enable signal is active, reset drive failure to prohibit any pulse, the output of the drive
Power component is turned off, the motor holding torque.
- Control signal connections
- PC control signal can be high, also can be low effective. When active high, the control signal
- The negative side together as a signal to active low, positive side of all control signals together as a signal common.
- For example, open-collector and PNP output interface circuit diagram is as follows:
- Note: the VCC is 5V, R short
- VCC value of 12V, R 1K, more than 1/8W resistor;
- VCC value of 24V, R 2K, more than 1/8W resistor;
- Set the motor per revolution steps

The drive to set the number of steps per motor revolution is 200 (whole step), 400 (2 segments), 1600 (8 segments), 3200 steps (16 segments).
The user can drive the front panel DIP switch SW3 is SW4 bit of the drive to set the number of steps (such as Table 1)

Table 1
- Set the output phase current
- To drive torque stepper motor, the user can drive panel DIP switch
- SW1, SW2 is to set the drive output phase current (RMS) unit amperes, the switch position
- Corresponding to the output current, output current value corresponding different types of drive. Concrete are shown in Table 2.
- Output Current (A

Current setting
- The semi-flow function is a step pulse 200ms, the driver output current is automatically reduced to the rated output current50%, used to prevent motor heating.
Fourth, the power interface
- 1, DC +, DC-: to connect the drive power
- DC +: DC power level, power supply voltage DC 12 to 48V. The maximum current is 5A. The
DC-: DC power supply negative level.
2, A + A-B + B-: to connect the two-phase hybrid stepping motor
Drive and two-phase hybrid stepper motor's connection with the four-wire system, the motor windings in parallel and series connection, and connection method, high-speed performance, but the drive current is large (for motor winding current of 1.73 times), Connected in series when the drive current is equal to the motor winding current.
Five, the installation
- Around to have 20mm of space, can not be placed next to the other heating equipment, to avoid dust, oil mist,
Corrosive gases, high humidity is too big and strong vibration. +
