Installation and Mounting:
1. Mounting Options: Screw mounting with M4 screws or DIN rail mounting.
2. Wiring: Detailed wiring examples provided for power supply and pulse signal connections.

Accessories and Options:
1. Noise Filter Set: For EMC compliance, a noise filter set (LEC-NFA) is recommended.
2. Controller Setting Kit: Includes software, communication cable, and USB cable for easy operation and setting.

Operational Guidelines:
1. Signal Timing: Detailed signal timing for return to origin, positioning, and pushing operations.
2. Teaching Box: Compatible with LECP6 series, offering easy and normal mode operations with detailed step data settings.

Important Notes:
1. Check Compatibility: Ensure actuator label matches the driver model number and I/O configuration (NPN or PNP).
2. Environmental Conditions: Operating temperature range is 0 to 40°C, with no freezing or condensation allowed.

Overview: The document also covers the Series LECPMJ step motor controller with CC-Link Direct Input Type, detailing functions, safety instructions, warranty, and compliance requirements.

Specifications: The controller supports CC-Link Ver. 1.10 communication, operates at various speeds, and can connect up to 42 controllers. Power supply requirements, communication specifications, and environmental conditions are outlined.
