Product Description:
The EL7332 EtherCAT Terminal is a 2 channel motion control module designed for direct operation of two DC motors. It uses compact drive technology and integrates seamlessly into EtherCAT based automation systems. The unit supports 24 V DC operation and delivers up to 1 A output current per channel. It enables fast efficient motor control in space constrained environments through direct motor connection and diagnostic feedback.
The EL7332 EtherCAT terminal provides a direct motor connection method with one DC output per channel. It supports two independent channels each with one end position input and one motor output. This design allows precise position based feedback and control. The terminal is galvanically isolated from the E bus that ensures signal integrity and safety. The supported load types include inductive DC brush motors. The output stage is safeguarded against overload and short circuit. A shared thermal overload warning system protects both output stages simultaneously. Diagnostic feedback is provided via light emitting diodes. The EL series EtherCAT module weighs approximately 50 g and can operate reliably in temperatures ranging from 0°C to 55°C.
The supply voltage of the Beckhoff EL7332 EtherCAT terminal for both electronics and power is 24 V DC. The maximum output current is 1 A per channel. The model features a 32 kHz PWM clock frequency with 180° phase shift to enable smooth motor control. The EtherCAT terminal modulates its output using pulse width modulation (PWM) where the duty cycle is voltage controlled and varies continuously between 0% and 100%. This allows precise analog equivalent control over the output signal. The resolution is up to 10 bit for current control and 16 bit for speed. Power contact current consumption is approximately 40 mA plus the motor current.
Frequently Asked Questions about EL7332:
Q: Does the EL7332 support accurate speed control with high resolution input values?
