Brake by hand

Keep press the button for 5s to unload completely, and then recover by hand.

Switch “ON” the brake switch

Brake by over current

25A (factory default,0~25A settable)Unload completely when reached the set current, and recover automatically after working 10mins.

Brake by overvoltage

320Vdc (factory default,220Vdc~320Vdc settable)PWM unload step by step once reached the set unload voltage, and it will unload completely if the voltage rise 20Vdc more.

Refer to “output overvoltage” control
