2.1 Product Introduction

Chapter Ⅱ Featured Functions

This chapter includes a brief introduction and main features of the controller.

SDMC20-S controller is used to control single-phase AC asynchronous motor, it has

abundant ports and logic functions, and its features include:

Soft startup: When starting, the motor speed will gradually increase from zero to

the set speed to eliminate the impact on the motor. Users can set the soft startup

time according to their needs.

Soft shutdown: Added a soft shutdown function, which can be set to 0.0~10.0

seconds to slowly stop the motor rotation.

Automatic speed stabilization: built-in digital PID control regulator to eliminate

the influence of voltage fluctuation or load change on motor speed.

Control output: The port supports NPN, PNP or push-pull output mode, with over-

current and short-circuit protection functions.

Switch sensor ports: 2 groups of overflow control ports, support NPN, PNP or

automatic adaptation type.

Intelligent photoelectric port: The on/off delay and sensitivity of intelligent

photoelectric sensor can be adjusted.

Motor stall protection: When the motor stalls, the controller stops output to

protect the motor.

There are up to three groups of logic signal sources for main output and control

output, users can freely combine them according to their needs.

Password lock and parameter lock function: After the controller is debugged, the

parameters can be locked to prevent misoperation by personnel.

Various control objects: The parameters of the control objects can be adjusted to

realize open-loop or closed-loop control of the motor, and can also control the

vibratory feeder.

Complete protection functions include: main output overcurrent protection,

overheating or overcooling protection, power supply undervoltage/overvoltage

protection, control output short circuit protection, 24V output short circuit

protection, speed regulation 5V output short circuit protection, and motor stall

protection.
