5.1 Simple mode parameter list
For simple variable-speed operation of the inverter, the initial setting of the parameters may be
used as they are. Set the necessary parameters to meet the load and operational specifications.
Parameter setting, change and check can be made from the operation panel. For details of pa-
rameters, refer to chapter 6.
NOTE Only simple mode parameter can be displayed using Pr. 160 "User group read selection". All
parameters are displayed with the initial setting. Set Pr. 160 "User group read selection" as
required. (Refer to section 6.17.4)

Tab. 6-45: Faults selected for retry
NOTES When terminal assignment is changed using Pr. 190 to Pr. 192, the other functions may be
affected. Make setting after confirming the function of each terminal.
For a retry error, only the description of the first alarm is stored.
When an inverter alarm is reset by the retry function at the retry time, the accumulated data
of the electronic thermal relay function, regeneration converter duty etc. are not cleared.
(Different from the power-on reset.)
Retry is not performed if E.PE (Parameter storage device fault) occurred at power on.
CAUTION:
E When you have selected the retry function, stay away from the motor and machine
unless required. They will start suddenly (after the reset time has elapsed) after
occurrence of an alarm.
When you have selected the retry function, apply CAUTION seals in easily visible
places.
