Q2HB110M is a constant angle and constant torque stepper drive. The driven voltage range from AC60V to AC110V. it can match 2-phase hybrid stepper motors whose rated current is under 8A and shaft diameter range from 86mm to 130mm. It is widely used in numerical device such as curving machine, middle-sized numerical machine and packing machine.
Features
* High performance, low price
* Two group 32 channels constant angel and constant torque subdivision. Highest subdivision: 200
* The motor phase current is reduced to set current value 100 ms after receiving the last pulse edge
* Bipolar constant current chopping circuit
* Optp-isolated input/output
* Driven current is adjustable continuously from 0.5A/phase to 8A/phase
* Single power supply, voltage arrange from AC60V to AC110V
* Highest response frequency: 200Kpps
* Overvoltage, overheat and overcurrent protection
Current setting
1. STOP/Im is the rotary switch that can set output current of holding motor status as 20%-80% of normal output current (increase in CW, decrease in CCW).
1. RUN/Im is the rotary switch for adjustment of the motor current.

Wiring example
Input signal oscillogram
Caution
1. Supply voltage shouldn’t exceed 110V.
2. Input control signal is 5V, current-limit resistance should be connected when over 5V.
3. O.H is overheat indicator. It lights and the drive shuts off if the drive temperature is over 70℃. It doesn’t work until the temperature falls to 50℃. The heat sink is needed when overheat occurs.
4. POWER is indicator of power supply. It lights when the driver is power on.

Specification
|
|
MF+
|
Positive of opto-isolated
|
Connected to +5V power supply. Driven voltage range from +5V to +24V. Current-limiting resistance is needed when over 5V.
|
|
MF-
|
Motor free signal
|
The motor current will be cut off and the drive stops working when it effects (low voltage).
|
|
SM+
|
Positive of opto-isolated
|
Connected to +5V power supply. Driven voltage range from +5V to +24V. Current-limiting resistance is needed when over 5V.

|
|
FL+
|
Positive of opto-isolated overheat / low voltage protection
|
The motor current is cut off automatically and signal FL- is active (low voltage ) when the temperature of the drive is over 70℃. The drive starts to work and the FL- is cleared when the temperature falls to 50℃.
|
|
FL-
|
Negative of opto-isolated overheat/ low voltage protection
|
Connect FL+ to current-limit resistance of output signal and FL- to ground. The maximum driven current is 50mA, the highest voltage is 50V.
|
|
TM+
