1 Introduction
Thank you for selecting the MOONS
’
SSDC series Step-Servo drive and motor. SSDC series
combines servo technology with a stepper motor to create a product with exceptional feature and
broad capability.
The SSDC series is a high performance, intelligent Step-Servo system with multi-axes field bus
control.
SSDC-A supports the RS-232 serial communication. The SCL commands and the Modbus
commands can be used to control the drive and motor in real time. The motion control program
can be stored in the drive (Q program) and then the SCL commands and Modbus commands can
be used to call programs flexibly.
