îš‹ Inverter Error Codes
The content of a current fault and faults that have occurred earlier can be read out by Memobus using the Fault
Trace (U2-) and the Fault History (U3-) parameters. The fault codes are shown in the table below.
îš‹ ENTER Command
When parameters are written in the Inverter from a PC/PLC using MEMOBUS communications, the parame-
ters are temporarily stored in the parameter data area of the Inverter. To enable these parameters in the param-
eter data area, an ENTER command must be used.
There are two types of ENTER commands:
• ENTER commands that enable parameter data in RAM only (changes will be lost after power loss)
• ENTER commands that write data into the EEPROM (non-volatile memory) of the Inverter and enable the
data in RAM at the same time.
An ENTER command is performed by writing 0 to register number 0900H or 0910H.

0900H Write parameter data to EEPROM, RAM is refreshed
0910H Parameter data are not written to EEPROM, but refreshed in RAM only.
IMPORTANT
• The EEPROM can be written up to 100,000 times only. Do not frequently execute ENTER commands (0900H)
which write into the EEPROM.
• The ENTER command registers are write-only registers. Consequently, if these registers are read out, error code
02H is returned.
• An ENTER command is not required if reference or broadcast data are sent to the inverter.
