D30/5/4Q-E1

Product catalog summary

Overview: The D30/5(7.5)/4(1)Q-E1 is a compact digital controller designed for controlling brushless motors up to 150 W (or 225 W) with digital Hall sensors. It supports both 4-quadrant and 1-quadrant operations.

Features:

Digital speed control operating as a closed-loop speed controller.
Maximum speed of 60,000 rpm for two-pole motors.
Set values via external analog voltage input or external PWM 200 Hz input.
Available SCI protocol for communication.
Preset rotation direction via digital signal.
Enable or disable output stage.
Monitor motor speed through 'FG' output.
Status indication via 'Ready' output.
Protection features include overvoltage, undervoltage, stall, and short circuit protection.
Built-in shunt regulator to limit controller power voltage.
Compact aluminum housing (110 x 80 x 34 mm).

Input Specifications:

Power input: Rated 12 - 30 VDC with ripple < 5%.
Control inputs: Analog speed command (0 - 3.3 VDC or 0 - 5 VDC), PWM speed command (200 Hz), current command (0 - 2 VDC), enable signal (+3.3 VDC), direction signal (+3.3 VDC), digital inputs 1 - 4 (+3.3 VDC).
Sensor position feedback via integrated 3 Hall effect position sensors.
Serial communication interface.

Operating Modes:

Speed controller supports open-loop and closed-loop, default is closed-loop.
Current limiter allows safe operation when preset current limit is exceeded.
