Description

ECM MOTOR SPEED CONTROLLER

The 792-ECM (Vma) motor speed controller is designed to provide both continuously variable and/or manually adjustable proportional speed control for all sizes and voltages of ECM DC Brushless motors. The 792-ECM (Vma) controller also includes an output to "enable" operation of ECM motors that require such a signal for operation.

Continuously variable speed control is accomplished via 2-10VDC or 4-20mA input signal to the control. This controller provides a linear increase of the output as the input signal increases over the 2-10VDC or 4-20mA span.

Manual Speed Control is accomplished by adjusting the control pot in the clock-wise direction to increase motor speed. Adjusting the pot in the counter clock-wise direction will slow down and eventually stop the motor as the PWM signal is removed.

The two control methods may be used together by manually setting a minimum speed for the motor to always maintain, regardless of input signal. When the input signal exceeds the level set manually, full variable speed control is resumed as long as the input is above the manually set level.

The 792-ECM is line voltage independent and requires only a 24VAC supply. This unit is circuit board on standoffs for mounting directly to control panel surfaces.

Variable speed control is accomplished via a Pulse Width Modulated (PWM) output signal. The PWM signal operates at a nominal 13.5VDC at 80 Hz and is capable of sourcing up to 5mA drive current to drive a single motor.
