8.7 Applicable Motor
1. A four-pole squirrel-cage asynchronous induction motor is the standard applicable motor. For non-standard
applicable motors, select an AC drive of required rated current.
2. In non-AC drive motors, the cooling fan and rotor shaft are coaxially connected. Cooling effect is reduced
at low speed. A cooling fan with better cooling effect or an AC drive motor must be used to avoid motor
overheating.
3. AC drive provides standard parameters for applicable motors. You can set a value or modify the default
value of the motor according to actual needs; otherwise, the motor running performance or protection may
be affected.
4. Alarm or even motor explosion may occur due to short circuit of cables or the motor. Perform insulation
short circuit test on the motor and cables installed for the rst time and routinely do this test. During the
test, the AC drive must be disconnected from the tested parts.
