 Electrical Protection

1Locked-rotor ProtectionOver-current limiting circuit protects motor from damage at least for 72 hours of locked rotor condition at rated voltage.
2

Maximum Current

under Locked Rotor

A, Typical inrush current when the motor is trying to re-start under locked rotor conditions is 2~4 times the normal running current reoccurring and for 16~20% of restarting cycle period.

B, If he CL function is used this restarting inrush current is about the same as the normal running current.
3Reverse Polarity ProtectionNo damage if the positive and negative leads are reversed under maximum operation voltage conditions.
4Over Voltage ProtectionThe circuit will be shut down automatically when input voltage over 284VAC. And re-started when Voltage down to 284VAC below.
5Soft StartIn 5 seconds after power on and speed control voltage gets to 1.5V or PWM duty cycle at 10% above.
