Communication with the controller

Note!
If no data for the initialisation of the controller are transmitted, the i700 servo inverter
uses the "Lenze setting" for the parameters.
Power up/Power down
In the case of "Power up" and "Power down", no undefined states can occur that cause
damage to the device or motor movements which are not requested or not braked.
In the case of a voltage failure/dip, there is no immediate response by the i700 servo
inverter. The functionality is to be maintained for as long as possible.
24-V supply voltage monitoring
Persistent data storage
A complete, persistent storage of the drive configuration which remains the same even
though the controller is switched off from time to time is carried out in the higher-level
controller instead of in the i700 servo inverter. Hence, the controller needs to transmit
the configuration data again to the i700 servo inverter after a power up.
However, in the case of a power down, the following device data are stored persistently
in the i700 servo inverter:
• Power-on and elapsed-hour meter (
or
for axis B)
•
