6-6 To Save the Change to the Holding
Register (Enter Command)
If a holding register write command (06h) or consecutive holding register write command (10h)
is used, the new register value will become effective but it will not be stored in the Inverter's
EEPROM memory. Accordingly, once the Inverter power is cut off the status will return to the
one effective before the holding register was changed.
To store the change to the holding register in the Inverter's EEPROM memory, issue an Enter
command according to the method specified below. When the control parameters are
changed, the motor parameters must be re-calculated.In this case, also perform recalculation
with the Enter command.

Issuing Method for the Enter Command

Use a Holding Register Write command (06h) to write into the holding register for Enter
command (0900h). At this time, the value to be written into the holding register (0900h) is as
follows.
0000
0001
0002 to FFFF
