Product Description

Q2HB44MB is a Constant angle, constant torque micro step driver, the drive voltage of which is from 12V to 40VDC. It is designed for use with the 2-phase hybrid stepper motor of all kinds with 42mm to 86mm outside diameter, 6, 8 leads, regulated phase current from 0.5A to 4A . The unique control circuit that it adopts can reduce motor’s noise, make motor run more smoothly, improve motor’s performance by 30% at high speed, reduce driver’s heating by 50%. It is widely used in the small numerical control devices with high resolution such as curving machine, laser labeling machine and etc.

 

Features

  • High performance, low price
  • 12/8 channels constant angle and constant torque micro step, highest micro step: 200
  • A unique control circuit is adopted
  • Highest response frequency: 200Kpps
  • Current of winding will be reduced by approximately 50% when no step pulse command is received for 0.1 second
  • Bipolar constant current chopping mode
  • Opto-isolated signal I/O
  • Drive current is continuously adjustable from 0.5A/phase to 4A/phase
  • Single power supply voltage from 12V to 40VDC

    Caution

    1. Please don’t reverse the power supply, supply voltage shouldn’t exceed 40VDC.
    2. Input control signal is 5V, current-limiting resistance should be connected when it is over 5V.
    3. Alarm indicator lights and the driver stops working when the driver temperature is over 70℃. It restarts working until the temperature falls to 50℃. The heat sink is needed when overheat occurs.
    4. 4.6 or 8 leads motors have to be used because of the special control circuit in the driver.

    TM

    Working indicator

    The green indicator lights when signal TM is effective.

    O.H

    Alarm indicator

    The red indicator lights when overheat occurs.

    Im

    Rotary switch for adjustment of the motor current

    Adjust motor’s phase current. Turning it in CCW will decrease the current and in CW will increase.

    +

    Positive of opto-isolated

    Connected to +5V power supply. Drive voltage ranges from +5V to +24V. Current-limiting resistance is needed when it is over 5V.,

    PU

    D4OFF, PU: step 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.

    D4ON, PU: positive step pulse signal

    DR

    D4OFF, DR is direction control signal

    Change motor’s direction of rotation. Input resistance is 220Ω. Low voltage 0-0.5V, high voltage 4-5V, pulse width>2.5μS

    D4ON, DR is negative step pulse signal

    SM

    Subdivision (micro step) setting signal

    Works as the subdivision set by D0-D3 at high voltage and as 4-phase 8-step (half step) at low voltage.

    MF

    Motor free signal

    The motor current will be cut off and the driver stops working when it is effective.

    TM

    Origin output signal

    When the motor current is on, the motor is at the origin position. (B, -A is on current); opto-isolated outputs (high voltage).

    FL

    Overheat signal

    The motor current is cut off automatically and signal FL is effective (low voltage) when the temperature of the driver is over 70℃. The driver restarts working and the FL is cleared when the temperature falls to 50℃
