MOONS’ Step Servo EtherCAT Drive

Manufactured by: MOONS'
Sold and Serviced by Motion Technologies Pty Ltd. Ph +61 2 9524 4782.

The SS-EC is a member of the Step-Servo family equipped with a built-in EtherCAT communication interface. This drive can operate as a standard EtherCAT slave using CANopen over EtherCAT (CoE). It is designed to work with various MOONS’ Step servo motors.

  • Programmable, digital step-servo drive and motor package
  • Operates from a 24 to 70 volt DC power supply
  • 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
  • Support modes: Profile Position, Profile Velocity, Profile Torque, Cyclic Synchronous Position, Cyclic
    Synchronous Velocity and Homing; as well as MOONS’ own Q mode
  • Dual port EtherCAT communication
  • USB port for configuration
  • Encoder resolution: 20000 counts/rev for AM17/23/24/34SS motor, 4096 counts/rev for AM11SS motor

MOONS’ Integrated Stepper Motor STM

Step motor systems have a natural tendency to resonate at certain speeds. The STM drive+motor automatically calculates the system’s natural frequency and applies damping to the control algorithm. This greatly improves midrange stability, allows for higher speeds, greater torque utilization and also improves settling times.

Microstep Emulation
With Microstep Emulation, low resolution systems can still provide smooth motion. The drive can take low-resolution step pulses and create fine resolution micro-step motion.

Torque Ripple Smoothing
All step motors have an inherent low speed torque ripple that can affect the motion of the motor. By analyzing this torque ripple the system can apply a negative harmonic to negate this effect, which gives the motor much smoother motion at low speed.

Command Signal Smoothing
Command Signal smoothing can soften the effect of immediate changes in velocity and direction, making the motion of the motor less jerky. An added advantage is that it can reduce the wear on mechanical components. Allows for three current settings to help the motor run cooler and reduce power consumption.

  • Running Current – the current the drive will deliver for continuous motion.
  • Accel Current – the current the drive will deliver when accelerating or decelerating.
  • Idle Current – reduces current draw when motor is stationary.

Self Test & Auto Setup
At start-up the drive measures motor parameters, including the resistance and inductance, then uses this information to optimize the system performance.
