Timing chart when power supply switch on
Control power supply L1C, L2C and the main power supply L1, L2, L3 at the same time
or before the main circuit power supply. If only the power supply of the control circuit is
connected, the servo is ready to signal (RDY) OFF.
After the main power is switched ON, the delay is about 1.5 seconds, and the servo signal
is ready (RDY) ON. At this time, the servo enabling command can be accepted, and it is
detected that the servo enabling is effective, the power circuit is turned ON, the motor is
excited, and it is in the running state. Servo enabled or alarm is detected. Power circuit is
closed and motor is in free state.
