Stepper Motor Driver 3A 30VDC 128 Segments HYQD40-H5742 Motor Driver for 57 42 Stepping Motor

Stepper Motor Driver 3A 30VDC 128 Segments HYQD40-H5742 Motor Driver for 57 42 Stepping Motor

Introduction:
- HYQD40-5742 is a two Phase professional motor drive. Can achieve positive control, through the 3 dial switch to select 8 gear subdivision control (1,2,4,8, 16, 32, 64128), the 3 bit code switch to select 6 gear current control (0.5A, 1A, 1.5A, 1.8A, 2.5A, 3A). Suitable for driving 57, 42 phase, four phase hybrid stepping motor. Can achieve low vibration, low noise, high speed drive motor.



Product features:
- The power supply has the anti reverse function
- The current by a dial switch
- adopts high-speed Optocoupler
- The high integration and high reliability
- The anti high frequency interference
-  the maximum voltage DC 40V
- The eight segment adjustable
-  semi-automatic flow
- The input terminal
- The input signal has three paths, they are:  step pulse signal CP+, CP-;  direction level signal DIR+, DIR- and offline signal EN+, EN-. Input signal interface has two kinds of connection: the user can according to need to adopt common anode or common cathode connection. (hereinafter to common connection method as an example)
- Common anode connection: the CP+, DIR+, EN+ connected to the power supply control system, if the power supply is +5V can directly access, if this power is greater than +5V, it shall be external plus a current limiting resistor R, which provides drive current is 8 - 15mA to drive internal coupling. Pulse input signal through the CP- access, the direction of the signal through the DIR- access, enabling signal via the EN- access. As shown in figure 1:



Note: EN is not connected, EN efficient when the rotor is in free state (offline), then can be manually rotated motor shaft, do your adjustment. Manual adjustment is completed, then the EN is set to an invalid state, to continue to automatic control
On the electrical wiring:
Phase 4 wire, 6 wire, 8 wire electrical wiring, as shown in figure 3:



The four line direct access; six line is not connected with the intermediate tap, the two connected together (intermediate tap according to resistance determination); eight lines can be used in parallel or series connection, parallel connection for the high current.
System wiring diagram:
Wiring power driver and controller, motor, with common connection method, for example, as shown in figure 4:



Note: please disconnect the power supply wiring, electrical wiring should pay attention not to phase error, phase to phase short circuit, so as not to damage the drive.
The fine fraction set
Fine fraction is to drive plate on the dial switch settings, depending on the options table data set (the best setting in the absence of power). Subdivision back stepping motor step angle is calculated according to the following procedures: step motor step angle = inherent / fine fraction. Such as: a natural step angle is 1.8 ° of the stepper motor in the 4 subdivision step angle is 1.8 ° /4=0.45 °
The driving plate dial switch 1, 2, 3 respectively corresponding to S1, S2, S3.



The current size of the set
The drive plate adjustable current range of 0.5A~2.8A, the specific data refer to the current selection table. The drive plate dial switch 4, 5, 6 respectively corresponding to S4, S5, S6.



On off-line function (enable):
Open the off-line function, motor rotor is not locked state, can easily rotate, when the input pulse signal does not respond, close this signal after receiving the pulse signal normal operation of motor.
