Example: Writing Constants from EEPROM in Operator to Inverter
• Enable the settings for
constants n001 to
n179.
• Execute write-in
(COPY) using the
Constant Copy Func-
tion Selection (n176).
A setting range check and matching check for the written constants are
executed after the constants are written from the Digital Operator to the
Inverter. If a constant error is found, the written constants are discarded
and the constants stored before writing are restored.
When a setting range error is found, the constant No. where an error
occurs is indicated by flashing.
When an inconsistency in the settings is found,
is indicated by flashing.
VERIFY Function
This function compares the constants stored in the Digital Operator with
the constant in the Inverter. Verification is possible only for the Invert-
ers with same product series, power supply specifications, and control
mode (V/f control or vector control).
When the constants stored in the Digital Operator are the same as those
in the Inverter, vFy will flash, and then End will be displayed.
