During installation, select the corresponding model (with/without brake, with/without encoder) according to the equipment layout, control requirements and power matching needs. For industrial automation installation scenarios, ensure that the coaxiality error between the reduction motor and the driven equipment is ≤0.1mm, and use standard mounting brackets to fix firmly to avoid vibration during operation. Strictly follow the modular installation specifications to ensure the reliable connection of each module interface. Select the appropriate high-efficiency synthetic gear oil according to the working conditions: use 150# for normal temperature and general load, 220# for high temperature and medium load. Regularly check the oil level, oil quality, sealing performance, heat dissipation status, brake wear and encoder signal; replace the lubricating oil after the first 2000 hours of operation, and perform comprehensive maintenance every 6000 hours thereafter, including checking gear meshing status, bearing temperature, fastener tightness and module connection integrity. If abnormal phenomena such as excessive noise, vibration, oil leakage, overheating or encoder signal failure occur during operation, stop the machine immediately for inspection and troubleshooting.
