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.
