Product catalog summary
Overview: The document outlines the technical specifications and system construction details for the Series LECS AC Servo Motor Drivers, including models LECSB, LECSC, and LECSS. These drivers are designed to work with various motor capacities and encoder types, and they support multiple communication protocols.
Specifications:
  • Power Supply Voltage: Options include 100 to 120 VAC and 200 to 230 VAC.
  • Motor Capacity: Available in 100W, 200W, and 400W.
  • Encoder Types: Incremental 17-bit encoder with 131072 pulse/rev resolution and Absolute 18-bit encoder with 262144 pulse/rev resolution.
System Construction:
  • Drivers are compatible with both incremental and absolute encoders.
  • Power supply options include single-phase and three-phase configurations.
  • Setup software and various cables are necessary for system integration.
Communication Protocols:
  • CC-Link and SSCNET III are supported for high-speed communication.
  • CC-Link supports up to 32 drivers with a maximum speed of 10 Mbps.
  • SSCNET III supports up to 16 drivers with a maximum bidirectional speed of 100 Mbps.
Functional Features:
  • Positioning by up to 255 point tables.
  • Parallel input and output options vary by model.
  • USB and RS-422 communication options are available but cannot be used simultaneously.
Environmental Conditions:
  • Operating temperature range is 0 to 55°C, with storage temperatures from -20 to 65°C.
  • Humidity should be 90% or less, with no condensation.
Ordering Information:
  • Models are specified by compatible motor type, power supply voltage, and encoder type.
  • Various connectors and cables are required for full system setup.
Wiring Instructions:
  • Main Circuit Power Supply Connector (CNP1): Connects to L1, L2, and optionally L3 for three-phase power.
  • Control Circuit Power Supply Connector (CNP2): Connects to L11 and L21 for control power.
  • Motor Connector (CNP3): Connects to U, V, W terminals for servo motor power.
Control Signal Wiring Examples:
  • LECSA: Requires connection to a PLC, with specific notes on preventing electric shock and supplying 24 VDC for interface use.
  • LECSB: Similar to LECSA, with additional notes on command pulse input methods.
  • LECSC: Includes instructions for CC-Link connections and notes on optical cable use.
  • LECSS: Details on SSCNET III optical cable connections and axis settings.
Options and Accessories:
  • Motor, Lock, and Encoder Cables: Various types and lengths available, with specific models for standard and robotic applications.
  • Regeneration Options: Different models available based on regenerative power requirements.
  • Setup Software: MR ConfiguratorTM for PC setup, requiring specific hardware and software conditions.
Important Notes:
  • Ensure protective earth (PE) connections to prevent electric shock.
  • Failure (ALM) signals are ON during normal conditions; OFF indicates an alarm.
  • Specific cables and connectors are required for proper operation and compatibility.
