{ 0 }
Only valid with option: " -EEP " (“plug-in EEPROM”):
Devices with option: " -EEP " (In preparation) are also equipped with an internal EEPROM and a
plug-in EEPROM ("Memory Module") which operates in parallel to this for the storage and
management of parameter data. The data from the inverter are managed in parallel on both
devices, so that a safe and rapid exchange of parameter settings in the device is possible for
commissioning or in case of service.
The data sets saved in the internal EEPROM and in the Memory Module can be copied between
the devices. This includes a PLC program that is present on the inverter.
0 = No change 2 = Internal
→
External , the data set is
copied from the internal EEPROM to
the memory module (external
EEPROM)
1 =
External → Internal
, the data set is
copied from the memory module
(external EEPROM) to the internal
EEPROM
3 = External < - > Internal , the data sets
are exchanged between the two
EEPROMs
Note: The device always used the data record which is saved in the internal EEPROM.

In this parameter, the cycle time for the system bus master mode and the CAN open encoder is
set (see P503/514/515):
[01] = CAN Master function , Cycle time for system bus master functions
[02] = CANopen Abs. encoder,
"CANopen absolute encoder"
, system bus cycle time of absolute

With the setting 0 = "Auto" the default value (see table) is used.
According to the Baud rate set, there are different minimum values for the actual cycle time:
