1. Phases shall be correctly connected while connecting
motor and the Driver.
2. Obvious heat generation of motor may occur under different driving conditions. Surface temperature of
motor is allowed to exceed 85°C during operation.
3. Motor must be positioned by installation rabbet on front cover of motor, attention shall be paid on error
matching, and the concentricity between motor shaft and load shall be controlled strictly.
