2. Stepper motor driver DM2722A
Detailed information:
FEATURES
DM2722A is a new-generation digital 2-phase stepper motor driver based on DSP control. The driver combines advanced DSP control technique and unique control circuit. The driver voltage is AC110-230V and driver current is below 7.0A. The driver can be used for types of 2-phase stepper motor with external diameter 86-130mm. The driver adopts circuit similar to servo control, so the motor can run smoothly with little vibration and noise. And the maximum positioning accuracy could reach 40,000 steps/rev. The product is widely used in big and medium-sized CNC equipment with higher resolution, such as engraving machine, medium-sized CNC machine tool, computer-controlled embroidery machine, packing machine, etc.
●
High performance, low price
●
The driver features 16-grade micro-stepping with equal angular degree and constant torque; the highest resolution may reach 40,000 steps/rev
.
●
The highest response frequency can reach
5
00Kpps
●
When the step-by-step impulse has halted for over 100ms, the coil current will automatically reduce to half of the set value, to effectively reduce motor warming

Signal port
1
PU+
Positive terminal of input
photoelectric isolation signal
Can be driven by +5 V-+24 V
2
PU-
DP5 = OFF, PU is step-by-step impulse signal
Falling edge is effective; whenever the impulse drops from high to low, the motor moves one step.
Requirements: pulse width> 2.5μS
DP5 = ON, PU is positive step-by-step impulse signal
3
DR+
Positive terminal of input photoelectric isolation signal
Can be driven by +5 V-+24 V
4
DR-
DP5 = OFF, DR is direction control signal
Used to change turning direction of the motor.
Requirements: pulse width> 2.5μS
DP5 = ON, DR is negative step-by-step impulse signal
5
MF+
Positive terminal of input photoelectric isolation signal
Can be driven by +5 V-+24 V
6
MF-
The motor release signal
When it is active (at low level), the motor wiring current is turned off, and the driver stops working; the motor is in a free mode.
7
RDY+
The driver is ready to output positive photoelectric isolation signal.
When the driver is in normal state, ready to receive controller signal, the signal is active (at low level).
8
RDY-
The driver is ready to output negative photoelectric isolation signal.

Possible problems & Solutions
Problem
Possible reason
Measure
Motor not run
No light with “POW” or ”ALM” indicator light

“
ALM
”
indicator light is on
To check overcurrent or overheating, motor missing
The motor shaft is locked, the motor cannot operate.
To check external control signal
Indicator light shows normal, and the motor shaft is unlocked
To check if MF signal is active
Motor blocked
The max speed is set too high
To lower the max speed
The time for speeding up is too short
To lengthen the time or increase the pulse filtering constant of the driver
Inaccurate position
The micro-stepping number is not correct
To select the correct micro-stepping number
Excessive load for the motor
To replace the motor or moderately increase running current of the driver
"Leakage" phenomenon
The driver and motor is not reliably grounded
To reliably ground the driver and the motor
Severe warming of the driver and the motor
Large running current of the driver or bad external thermal conditions
To moderately reduce driver running current or improve ventilation of the driver and the motor
Caution
1 The input voltage is lower than AC270V.
2. Falling edge is effective of input pulse signal. If you need the rising edge to be effective, please set inner parameter of the driver.
3. When the driver temperature goes beyond 75 degrees, it will halt working, and the fault indicator ALM will be on. Until the temperature drops to 50 degrees, the driver may resume work after a second-time power-on. In case of such overheat protection, please install heat sink.
4. In case of overcurrent (short circuit of load), the fault indicator ALM will be on. Please check motor wiring and other fault of short circuit; after the fault is removed, it will resume upon a second-time power-on.
5. In case of no motor, the fault indicator ALM will be on. Please check motor wiring; after the fault is removed, it will resume upon a second-time power-on.
