Daily Operation Maintenance

Keep motor outer surface clean, avoid cutting fluid & dust accumulation blocking natural heat dissipation

Regular inspect power and encoder plug locking status every half year, prevent loose wiring causing communication failure or motor overcurrent alarm

Before spare motor replacement, confirm winding code 144 and PG1 encoder-brake specification consistent with original unit

Long-term spare storage needs dry constant-temperature warehouse, regularly energize brake coil to prevent brake rust adhesion
