Parameter functions: Set the minimum output torque for motor locked rotor judgment. When rotor locking occurs during running of the motor due to mechanical reasons, the motor will continue output according to settings of P0-06 and P0-07 as the motor speed fails to reach the command value. As the motor does not rotate, this will cause heating of the driver and the motor, and further result in damage. The driver is provided with a motor locked rotor protection function to solve this problem. Logic for locked-rotor judgment: Parameter functions: Set the maximum motor speed for judging whether the motor has a locked motor when locked-rotor protection of the motor is activated.
When P8-15 = 0, the locked-rotor judgment function is off. Parameter functions: Set the lasting period for judging whether the motor has a locked motor when locked-rotor protection of the motor is activated. Parameter functions: Set the maximum torque of the motor in the locked rotor state when locked-rotor protection of the motor is activated. Parameter functions: P8-18 bit0: Torque limit function upon voltage drop of the main circuit bit0 = 0: Turn off the torque limit function upon voltage drop of the main circuit, when P8-22 and P8-23 are invalid bit0 = 1:
Turn on the torque limit function upon voltage drop of the main circuit; when the bus voltage is detected to be lower than 80% of the rated value, the output torque of the motor will be limited to the value set by P8-22.
