Electrical Protection:
| 3-1 | Locked-rotor Protection | Over-current limiting circuit protects motor from damage at least for 72 hours of locked rotor condition at rated voltage. |
| 3-2 | 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. |
| 3-3 | Reverse Polarity Protection | No damage if the positive and negative leads are reversed under maximum operation voltage conditions. |
| 3-4 | Over Voltage Protection | The circuit will be shut down automatically when input voltage over 30VDC. And re-started when Voltage down to 30VDC below. |
| 3-5 | Soft Start | In 5 seconds after power on and speed control voltage gets to 1.5V. |
