Product Detail

SH2034D
Stepping Motor Driver
I?Summarize
Based  on the original stepping motor driver, we developed the 2034D type stepping  motor driver. This driver owns many advantages such as lower noise, higher  efficiency, lower temperature rise, convenient settings, nicer running  characteristic and so on.
II?The using and instruction of the motor  driver







Power supply: 


Single  external power supply:AC 20-40V 3A or DC 20-50V 3A?
Warning: The value of the power  supply shouldn’t be  over this range.
Wiring  diagrams of motors:
For two-phase four-wire motor:

Phase	A+	A-	NC	B+	B-
Wire	Red	Green	White Black	Yellow	Blue

For four-phase six-wire motor:

Phase	A+	A-	B+	B-
Wire	Red	Green	Yellow	Blue

For four-phase eight-wire motor, there are two  modes:
 i. Parallel-wound

Phase	A+	A-	B+	B-
Wire	Red Blue	Yellow Black	White Brown	Green Orange

ii.  Series-wound

Phase	A+	A-	Nc1	B+	B-	Nc2
Wire	Red	Black	Yellow Blue	White	Green	Brown Orange

Warning:Motor’s  wires mustn’t be connected wrongly, Otherwise, the driver will be mangled.
Input  signals
The inner interface circuits of the SH2034D are segregated by optically coupled  isolators.
There are three connecting mode between the controller and the driver.
i. Differential                                       ii. Common-anode





iii. Common-cathode






Signal    Amplitude	R
5V	---
12V	680O
24V	1.8KO







DIR:Input  port of the direction signal. High/low level controls the CW/CCW of motor. The  changing edge of the signal must be at least 2.5us later or earlier than the  falling edge of CP;
FREE: Free signal (active low). when this input end is low level,there will be no holding torque of the motor.
CP: Pulse signal input. active by the falling edge,the  highest response frequency can be 200kHz,low level pulse width should be not less than 2.5us?
Warning:Input signal must have enough current, (Currently, TTL, COMS signal are  not drive firsthand). Otherwise, System can not run normally.
* phase current and subdivision number setting:
Shift switch is adopted to set phase  current and subdivision number in SH2034D driver. There-into, Switch 5 is half  phase-current (ON means full current, OFF means half), switch 6 is the setting  of single or double pulse (ON show single pulse CP,DIR; OFF show double pulse  CW,CCW). See Table2,Table3.After the subdivision of driver is set, the  step angle in motor is equal to whole step angle divided by subdivision number.  For example:if subdivision number is set to 18 and the motor is 2-phase,its subdivision step angle is 1.8°/18=0.1°?
Warning:shift switch ON=0,OFF=1.

III?Installation Dimension:
 Disperse heat by compelling structure is adopted, so when installing, please  keep enough space to elimination of heat when the driver installed (unit: mm)



IV. Signal indication

Phenomenon	Case	Solutions
The signal    light twinkles red (over current)	i. The motor wires are shortcut.      ii. The motor is broken.	i. Examine the motor wires.      ii. Change the motor.
The signal    light twinkles red and orange. (overvoltage)	The power    supply is over the range.	Turn down the    power supply.
The signal    light be red. (under the lowest voltage)	The supply is    too low.	Turn up the    power supply.
The signal    light twinkles red and orange.      (over temperature)	i. The temperature of the driver is too high.      ii. The temperature of surroundings is too high.	i. Enlarge the    proportion of radiator.      ii. Lower the temperature of surroundings.
The power    light is red	The fuse is    broken.	Change the    fuse in the same type.
