2.2.9 Turn on/off response of the servo amplifier
The turn on/off response of the servo amplifier is shown below.
5 seconds after being turning on the 24 V auxiliary supply (start time of the micro control-
ler), the "Drive ready" signal is set to high.
The above image shows when the 24 V auxiliary supply activates the system by turning
on the main switch and the main supply is later engaged. 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 volatile memory, parameters received must be stored in the
host controller. The advantage here is in the automatic download of program data when
an amplifier is exchanged.
If the main supply is turned on, the capacitors in the intermediate circuit are loaded. Ap-
proximately 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 interme-
diate circuit is discharged.
