8.1.4
Setting the date and time
An accurate device time setting makes it easier to troubleshoot later.
Faults which occur during operation are stored in an event log with date and time of day.
Set the current date and time under "P-EXTRAS/Date" and "Time" respectively.
●
The current time of the testing date is set as CET at the factory.
●
Winter and Summer time are not taken into account.

Setting the level of detail of the inverter menu
Set the level of detail of the inverter menu in the menu "P-EXTRAS" to change the number of
visible menus and parameters and to increase the display clarity.

Inverter operating commands
The converter is operated by using various inputs, such as control cable terminal block
inputs, control words via fieldbus, signal generators etc. Further information can be found
under "Configuring operating sources" (Page 128).
The commands have the following functions:
●
"Controller enable"
The power unit in the converter, consisting of IGBTs, is only active when controller is
enabled. As well as the options for releasing the controller by software, control cable
terminal -A1-X2:8 must also be activated. If you deactivate this function, the output
semiconductor is blocked immediately and the motor coasts to a stop.
●
"Speed in"
Use this command for controlled shutdown of a motor. The motor passes through a brake
ramp during shutdown. The converter is immediately ready for a restart after the braking.
●
"Reset"
Acknowledge a queued error using the command "Reset". The converter also takes into
account a shutdown using functions "Fast stop" or "Off1" and "Off2".
●
"Off1 (NC)" and "Off2 (NC)"
–
Perform a controlled braking with the command "Off1". This command is initiated by
software. Perform an immediate block with the command "Off2". An optional main
contactor drops out. Acknowledge the converter before restarting using the "Reset"
command. When restarting, the converter must first be pre-charged.
–
The control via the control cable terminal block of "Off1" and "Off2" is realized using an
NC (normally closed) contact.
