EEPROM copy order

{ 0 }
The frequency inverter is 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
device 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 device.
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:
Since software version 1.4 R2, the frequency converter always uses the data record
that is stored on the internal EEPROM.
With older versions the data record for the external EEPROM (memory module) is
used. The parametrisation of the internal EEPROM was only used if no Memory
Module was plugged in.

CAN Master cycle
(CAN Master cycle time)

0.0 / 0.1 … 100.0 ms
{ all 0.0 }
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
encoder
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:
