1 Introduction
Thank you for selecting the MOONS’ STF series stepper drive. The SSDC-EC series are high
performance fieldbus control stepper drive which also integrates with built-in motion controller. The
SSDC-EC drive can operate as a standard EtherCAT slave using CANopen over EtherCAT (CoE).
EtherCAT® is registered trademark and patented technology, licensed by Beckhoff Automation
GmbH, Germany.
1.1 Features
• Programmable, digital step-servo drive and motor package
• CANopen over EtherCAT (CoE) with full support of CiA402. Based on the widely used
100BASE-TX cabling system and with a baud rate of 100Mbps full-duplex, EtherCAT enables
high speed and highly reliable communication
• Supported modes: Profile Position, Profile Velocity, Profile Torque, Cyclic Synchronous
Position, Cyclic Synchronous Velocity and Homing mode as well as MOONS’ own Q mode
• Control modes:
Velocity Control: Digital signal control, Analog control, SCL command, Q programming
Position Control: Digital signal control, Analog control, SCL command, Q programming
Torque Control: Analog control, SCL command, Q programming
• Multi-operation modes:
Closed-loop Servo control mode, Closed-loop Step control mode, Full closed-loop mode
• Current output
SSDC03 output current：continuous 3A/phase（peak of sin），boost 4A(1.5s)
SSDC06 output current：continuous 6A/phase（peak of sin），boost 7.5A(1.5s)
SSDC10 output current：continuous 10A/phase（peak of sin），boost 15A(1.5s)
• Wide range input voltage:
SSDC03：12~48VDC
SSDC06：24~70VDC
SSDC10：24~70VDC
• Encoder resolution：
20000 counts/rev (AM17/23/24/34SS-N motor)
4096 counts/rev (AM11/17/23/24/34RS motor)
• Differential encoder outputs (ENC A+/-, ENC B+/-, ENC Z+/-), 26C31 line driver, 20 mA sink or
source max
• Support secondary encoder signal input(single-ended or differential) for full closed-loop control
• Abundant I/O interface
8 optically isolated digital inputs,5-24VDC
4 optically isolated digital outputs,max30V/100mA
2 analog inputs can be configured to 0-5V, 0-10V, ±5V or ±10V signal ranges
Communication
Dual-port RJ45 for EtherCAT communication
RS-232 serial port for configuration
