●
With a heavy load, in the case when a motor starts or the target frequency is adjusted (increasing),
the motor speed often can not tightly follow the output frequency. If the motor speed is lower than
the output frequency, the output current will increase to improve the output torque. However, if the
difference between the output frequency and the motor speed is too great, the motor torque will
decrease, which is called
‘
stall
’
