LS Electric L7CA servo systems combine a high-performance servo motor with a servo amplifier (drive) to achieve accurate position, velocity, or torque control. Automatic tuning, built-in indexer and other standard features make this series an extremely cost-effective offering. Select system size based on power/torque requirements. Add power and feedback cables plus an I/O breakout module for a complete system.

LS Electric® L7C Servo Systems - Servo Motors and Servo Drives
LS Electric® L7C Servo Systems - Servo Motors and Servo Drives
Basic features at a fantastic price!
LS Electric Servos provide the most requested features: setup wizards, auto tuning, built-in indexer and more - in an extremely cost-effective package:
- 5 standard servo systems from 100W to 1kW
- 200-230VAC single-phase input power on all systems
- Control via high-speed pulse train, analog speed or torque signal, or internal indexing
- Use with AutomationDirect CLICK, Do-more BRX, or Productivity series PLCs; or any other host controller or HMI
- Auto-Tuning and FREE setup software (with built-in o-scope function)
- Fully digital with up to 1kHz velocity loop response
- 30-day money-back guarantee
- Two-year warranty
Drive Features
- Easy setup and diagnostics with built-in keypad/display or the DriveCM PC-based software
- Field upgradeable firmware ensures the drive can always be upgraded to the latest operating system
-
Command options include:
- ±10V torque or velocity command
- Pulse train or master encoder position command
- Real-time selectable electronic gearing
-
Internal Indexer for position/speed-based moves:
- 64 individual move statements can be configured
- Each move includes distance, speed, accel, decel, registration, and dwell parameters
- Set up through free downloadable Drive CM software or via serial comms (PLC, HMI, w/ Modbus via RS485 or RS422)
- The move can be initiated via digital inputs or through serial comms
- Index profiles include relative or absolute moves, registration, blended moves, and positive/negative/shortest distance rotary table moves.
-
Two auto-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:
- 10 inputs
- 5 general purpose, configurable outputs
- 3 outputs permanently configured for alarm & status codes
- 1 line driver encoder output (with scalable resolution)
- Software-based oscilloscope feature that can monitor a variety of command and status signals, including output speed, torque, power, and more
- Standard 50-pin DIN-rail mounted break-out kit for the drive's CN1 connector (with screw terminal connections), or 50-pin cables with flying leads
Servo Motor Features:
-
Five low inertia models:
- 100W, 200W, 400W, 750W and 1kW
- Speeds up to 5,000 rpm
- Permanent magnet 3-phase synchronous motors
- Keyed drive shafts support clamp-on style couplings or key-style couplings
- Integrated encoder with 17-bit resolution (131,072 pulses per revolution)
- Optional 24 VDC spring-set holding brakes (AYK2 motors)
- Standard hook-up cables for motor power, encoder, and brake in standard or flex-rated lengths of 3, 5, 10, and 20m

LS Electric L7C Servo Systems Overview
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)
Need more features? If you need more advanced features or high torque output - please check out our SureServo2 servo systems with a much more extensive feature set AND motor output power up to 15kW.
LS Electric L7C Series Motors, Drives, and Motor Cables
All the popular AC servo system features at a fantastic price!
L7CA Servo Drives:
- Two servo drive sizes 400W and 1kW
- L7C drives accept 230 VAC single-phase input power
Matching Motors:
- 100W, 200W, 400W, 750W, & 1kW
- Speeds up to 5,000 rpm
CN1 I/O Components
These accessories are required for interface to the on-board drive I/O (via the CN1 connector):
- The 50-pin DIN-rail mount terminal block interfaces to all the drive I/O signals
- Choose from 3 cable lengths to locate the DIN-rail mount version
- A 50-pin to pigtail cable is also available to interface the I/O signals
Accessories
Optional accessories for LS Electric L7CA servo systems include braking resistors, EMI input filters, and a set of pre-matched gearboxes for easy mounting to the appropriate servo motor.
Use the gearboxes to increase the available torque or to solve inertia mismatch problems.
The free downloadable Drive CM software enables programming, backup, and troubleshooting options. Link to software can be found on any of the drive components item pages.
Servo Connector Components
Connector components for LS Electric L7CA servo systems can be used to create custom cables for encoder feedback, and the I/O connection. For the most reliable results, utilize the factory-made cables wherever possible. A replacement power connector for the drive is also available.
