D30/5/4Q-E2

Product catalog summary

Overview: The D30/5(7.5)/4(1)Q-E2 is a compact digital controller designed for managing brushless motors up to 150 W or 225 W, utilizing digital hall sensors. It supports both 4-quadrant and 1-quadrant operations.

Key Features:

Operates as a closed-loop speed controller with a maximum speed of 60,000 rpm for motors with 2 poles.
Accepts set value inputs via external analogue voltage (0 to +3.3 V) or PWM at 200 Hz.
Includes SCI protocol for communication and allows direction of rotation to be preset by a digital signal.
Features motor speed monitoring, status indication, and motor block protection.
Offers protection against over-voltage, under-voltage, motor block, and short-circuit.
Equipped with a standardized connector strip and a built-in shunt regulator to limit supply voltage.

Output Specifications:

Drive output to one brushless motor is 0.95 times the supply voltage VCC.
Speed output is 20 times the output frequency.
Shunt regulator output "PR" has a maximum of 10 A for models D30/5/4Q-E2 and D30/7.5/4Q-E2.
Operation current is 5 A with a peak phase current limit of 10 A for D30/5/4Q-E2 and D30/5/1Q-E2, and 7.5 A with a peak phase current limit of 20 A for D30/7.5/4Q-E2 and D30/7.5/1Q-E2.
PWM frequency is set at 50 kHz.

Input Specifications:

Nominal power supply input range is 12 - 30 VDC with ripple less than 5%.
Control inputs include analogue speed command (0 - 3.3 VDC), PWM speed command (200 Hz), and current command (0 - 2 VDC).
Enable and direction signals are at +3.3 VDC, with digital inputs 1 to 4 also at +3.3 VDC.
Position feedback is provided through interfaces to 3 hall effect position sensors integrated into the motor.

Operating Mode:

Default operation as a closed-loop speed controller.
Current limiting feature allows safe operation beyond preset current limits.

General Specifications:

Microprocessor: STM32F103C8T6.
Efficiency: 95%.
Mounting: Plug-in with female headers RM 2.54 mm and RM 2.0 mm.
Dimensions: 48 x 35 x 12.7 mm.
Weight: 12 g.
