Q2HB110 2-phase stepper motor driver
Product Description
Q2HB110 full / half stepper drive, driven voltage range from AC60V-AC110V. it can match2-phase hybrid step motors whose rated current under 8A and shaft diameter range from 86mmto 130mm. It is widely used in numerical device such as curving machine, embroidery machine and packing machine.
Features
* High performance, low price
* Highest response frequency: 200Kpps
* The motor phase current is reduced to set current value 100 ms after receiving the last pulse edge
* Bipolar constant current chopping circuit
* Opto-isolated input/output
* Driven current is adjustable continuously from 0.5A/phase to 8A/phase
* Single power supply, voltage arrange from AC60V to AC110V
* It can work as 2 phase 4 step or 4 phase 8 step
* 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).
2. RUN/Im is the rotary switch for adjustment of the motor current.

Wiring example
Caution
1. Supply voltage shouldn’t exceed 110V.
2. Input control signal is 5V, current-limiting 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).
|
|
DR+
|
Positive of opto-isolated
|
Connected to +5V power supply. Driven voltage range from +5V to +24V. Current-limiting resistance is needed when over 5V.
|
|
DR-
|
DP2=ON, DR is direction signal
|
Change the motor’s direction of rotation. Input resistance: 220Ω. Low voltage: 0-0.5V, high voltage: 4-5V, pulse width>2.5μS
|
|
DP2=OFF, DR is negative pulse signal
|

|
PU+
|
Positive of opto-isolated
|
Connected to +5V power supply. Driven voltage range from +5V to +24V. Current-limiting resistance is needed when over 5V.
|
|
PU-
|
DP2=ON, PU is pulse signal
|
With the falling edge of the signal PU, the motor executes an angular step. The Input resistance is 220Ω. Low voltage: 0-0.5V, high voltage: 4-5V, pulse width>2.5μS.
|
|
DP2=OFF, PU is positive pulse signal
|

|
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.
