Turn on/off Response of the Servo Amplifier
The turn on/off response of the servo amplifier is shown below.
Five seconds after turning on the 24 V auxiliary supply (start time of the micro controller),
the "Drive ready" signal is set to high.
The above image shows when the 24 V auxiliary supply activates the system through
turning on the main switch and the main supply is engaged later. This, however, is not
absolutely necessary. The main supply can also be activated with the 24 V auxiliary supply
at the same time.
Since the servo amplifier has a volatile memory, received parameters must be stored in the
host controller. The advantage here is in the automatic download of program data when an
amplifier is changed.
If the main supply is turned on, the capacitors in the intermediate circuit are loaded.
Approximately 0.7 seconds are needed.
If the main supply is turned off, the current of intermediate circuit is maintained and can be
used for controlled braking of the motor. If the motor is slowed, the energy is returned to the
intermediate circuit.
If the motor is stopped, the "enable" signal can be removed. After 5 minutes, the
intermediate circuit is discharged.
