LS Electric iX7 (iX7NH Series) EtherCAT and ModTCP Servo Systems

LS Electric iX7 servo systems offer advanced multi-axis motion control functions over EtherCAT and ModbusTCP networks.

• 9 standard servo systems from 100W to 3.5kW
• Multiple input power options:
• 110VAC single-phase up to 400W
• 230VAC single-phase up to 2.2kW
• 230VAC three-phase in all sizes
• Use with any CANopen over EtherCAT (CoE) compatible PLC/host controller or one with ModbusTCP capability
• Fully digital with 1kHz velocity loop response
• 45-day money-back guarantee
• Two-year warranty

Servo Drive Features:

• Easy setup and diagnostics via EtherCAT or free Drive CM PC-based software
• Field upgradeable firmware ensures the drive can always be upgraded to the latest operating system
• Safe Torque Off (STO) eliminates the need for large external contactors for e-stop handling
• Network control options include:
  • Cyclic Mode - all drives are updated every EtherCAT cycle (~1 millisecond) with position, velocity, or torque setpoints
  • Profile Mode - drives receive target setpoints for each move over EtherCAT or ModbusTCP
• Motion capabilities include:
  • All motion parameters are stored, loaded and triggered in the PLC (simplifying your control scheme)
  • Define up to 400 position setpoints (per axis) in the PLC, then trigger those moves over the network
  • Electronic camming (E-Cam) in the PLC, - create multiple gear ratios between axes and switch ratios on-the-fly
  • Registration - set up precise registration corrections with sensor input, and automatically correct for inconsistencies or variations in products or processes
  • Flying Shear - a traversing axis tracks the motion of material feed to make cuts on-the-fly, without having to stop or pause production (material flow)
  • Advanced Torque Control - for precise tensioning and winding applications
• Multiple tuning modes:
  • Off-Line auto tuning (the drive initiates moves while auto-tuning)
  • On-Line auto tuning (an external controller sends move commands during auto-tuning)
  • Manual tuning allows the user to adjust all tuning values
• Optically isolated digital I/O:
  • 6 configurable digital inputs
  • 3 configurable digital outputs
  • 1 analog input (±10VDC for torque limit only)
  • 2 analog outputs (±10VDC) for monitoring 20+ drive values
• Software-based oscilloscope feature that can monitor a variety of command and status signals, including output speed, torque, power, and more
• Standard 20-pin DIN-rail mounted break-out kit for the drive's CN1 connector (with screw terminal connections), or 20-pin cables with flying leads

Servo Motor Features:

• Six low inertia models:
  • 100W, 200W, 400W, 750W, 1kW, and 1.5kW
  • Speeds up to 5,000 rpm
• Three medium inertia models:
  • 1.6kW, 2.2kW, 3.5kW
  • Speeds up to 3,000 rpm
• Permanent magnet 3-phase synchronous motors
• Keyed drive shafts support clamp-on style couplings or key-style couplings
• Integrated absolute encoder with 19-bit resolution (524,288 pulses per revolution)
• Optional 24 VDC spring-set holding brakes (MK2 motors)
• Standard hook-up cables for motor power, encoder, and brake in standard or flex-rated lengths of 3, 5, 10, and 20m

Why Use a Servo?

Servo systems provide the highest possible level of performance for precise control of position, velocity, and torque. Compared to lower cost stepping systems, servo systems provide:

• More torque at higher speeds (up to 5,000 rpm)
• Higher response with closed-loop control (high hit rate without stalling or lost position)
