Cnc 4A 2 phase hybrid stepper motor driver controller
High performance 4A 40V Stepping motor driver
The motor phase current is reduced to approximately 50% of the set current value
100 ms after receiving the last pulse edge
Single power supply, voltage range from DC12V to 40V
1. Please don t reverse the power input, supply voltage shouldn t exceed DC40V.
3. Alarm indicator lights and the drive shuts off if the drive temperature is over 70 . It dose not work until the temperature falls to 50 . The heat sink is needed when overheat occurs.
ON, double pulse PU is positive pulse signal, DR is negative pulse signal
OFF, single pulse PU is pulse signal, DR is direction signal
The red LED lights when overheat occurs.
With the falling edge of the signal PU, the motor executes an angular step. The Input resistance is 220 . Low voltage: 0-0.5V, high voltage: 4-5V, pulse width>2.5 S.
D4=ON, PU: positive pulse signal
Connected to +5V power supply. Driven voltage range from +5V to +24V. Current limiting resistance is needed when over 5V.
Change the motor s direction of rotation. Input resistance: 430 . Low voltage: 0-0.5V, high voltage: 4-5V, pulse width>200 S
D4=ON, DR: negative pulse signal
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 .
Negative of opto-isolated overheat output signal
Connect + to current limiting resistance of output signal and connect FL to ground. The maximum driven current is 50mA, the highest driven voltage is 50V.
The first is US$19.9 the another is US$8 per each
