Product catalog summary

General Description:
The D30/7.5/4QF-E3xay is a compact 4-quadrant digital controller designed for brushless motors up to 180 W. It features various housing and terminal configurations, including metal and bare options with horizontal and vertical terminals.

Features:

Digital speed control with closed-loop operation.
Maximum speed of 60,000 rpm for motors with 2 poles.
Set value input via external analogue voltage (0-5 V) or PWM at 200 Hz.
Supports SCI protocol and offers sensor-based trapezoidal or Field-Oriented Control (FOC).
Includes built-in motor choke and direction control via digital signal.
Protection against over-voltage, under-voltage, motor block, and short-circuit.
Shunt regulator to limit supply voltage.

Technical Specifications:

Input Specifications: Nominal power supply range of 12-30 VDC with less than 5% ripple. Control inputs include analogue and PWM speed commands, enable and direction signals, and digital inputs.
Output Specifications: Drive output to one brushless motor with a shunt regulator output max of 3 A. Operation current is 7.5 A with a peak phase current limit of 16 A.
PWM Frequency: 20 kHz for certain models and 50 kHz for others.
