Installation Guidelines

Mounting Alignment: Ensure precise alignment between the motor shaft and the driven load. Misalignment exceeding specifications can damage the coupling, motor bearings, or shaft.
Environmental Protection: While rated IP67, protect the motor from continuous exposure to liquids and avoid submerging. Ensure the cable connectors are correctly sealed and locked.
Thermal Management: Provide adequate ventilation space around the motor frame to facilitate natural convection cooling. Do not block the heat-dissipating surfaces.
Wiring: Ground the motor frame to the protective earth terminal of the servo amplifier to suppress electromagnetic interference (EMI) and prevent electrical hazards.
