Compact Equipment Design Made Possible Through Efforts to Downsize

This speed controller is designed to save installation space.
Volume is 45 % less than that of a conventional speed controller, and 70 % less than that of a commonly used inverter.
The MSC-1 can be mounted directly to a 35 mm wide DIN rail.

Speed Controller Performance

Allows for Stable Speed Control

The MSC-1 uses closed loop control, which results in a smaller drops in speed due to load fluctuations compared to inverters with open loop control.
Use of CPU control for the control circuit has improved speed regulation (versus load) compared to conventional speed controllers. This allows for more stable speed control.

Difference in Speed Change Between MSC-1 and a Commonly Used Inverter

Less Noise is Generated by the Controller

Inverters control the rotation speed of the motor by controlling the magnitude and frequency of the voltage supplied to the motor using the PWM control method.
The speed controller controls motor rotation speed by controlling the magnitude of the voltage supplied to the motor using the phase control method. The phase control method generates less noise because the supply voltage is not turned ON and OFF as frequently as in an inverter.

For an Inverter + Three-Phase AC Motor

For MSC-1 + Speed Control Motor

Compatible With a Wide Range of Voltage Specifications and Motor Output Power

Compatible With Single-Phase 100~230 VAC Voltage Specifications

Compatible with multiple voltages from single-phase 100 to 230 VAC, the MSC-1 can be used worldwide.*

• *While the MSC-1 speed controller is designed for single-phase 100~230 VAC, make sure to use a motor that matches the voltage specifications of your equipment.

Capable of Controlling Motors With Output Power From 6 to 60 W

Compatible with speed control motors with output power from 6 W to 60 W.

Full Range of Operating Patterns

Equipped With Alarm Output Function

MSC-1 monitors the operating status of the motor.
An alarm signal is output when a heat generation abnormality occurs, such as a motor lock due to overload, and the power supply to the motor is stopped (coasting stop).
The motor can be restarted by turning on the alarm reset input. The alarm content can be identified by the LED blink count.

Speed Output Function

Outputs a signal of 12 pulses per motor revolution, synchronous with motor operation.
Rotation speed can be calculated from the frequency of this signal.
