Electrical Protection
| 1 | Locked-rotor Protection | Over-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. |
| 3 | Reverse Polarity Protection | No damage if the positive and negative leads are reversed under maximum operation voltage conditions. |
| 4 | Over Voltage Protection | The circuit will be shut down automatically when input voltage over 284VAC. And re-started when Voltage down to 284VAC below. |
| 5 | Soft Start | In 5 seconds after power on and speed control voltage gets to 1.5V or PWM duty cycle at 10% above. |
