3. 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 60VDC. And re-started when Voltage down to 60VDC below. |
3–5 |
Soft Start |
In 5 seconds after power on and speed control voltage gets to 1.5V or PWM duty cycle at 10% above. |
