Description
This function automatically reduces
the carrier frequency to 2.5 kHz if the
output frequency is 5 kHz or less, and
the output current is 110% or greater
than the rated Inverter current. Nor-
mally this setting is not necessary.
This function improves the overload
capacity at low frequencies.
0: Low carrier frequency at low speed
disabled.
1: Low carrier frequency at low speed
enabled.
Note Normally, it is not necessary to
change the default setting.
Note This function is enabled if n080
(carrier frequency) is set to 2, 3,
or 4.
Select the function to read, copy, and
verify the parameter between the
memory of the Inverter and that of the
Digital Operator.
rdy: Ready to accept the next
command.
rEd: Reads the Inverter parameter.
Cpy: Copies the parameter to the
Inverter.
vFy: Verifies the Inverter parameter.
vA: Checks the Inverter capacity
display.
Sno: Checks the software number.
Note No parameters can be copied to
the Inverter in RUN operation.
Select the copy-prohibit function.
Set this parameter to store the data in
the EEPROM of the Digital Operator.
0: Read prohibited for Inverter
parameters (data cannot be stored
in EEPROM).
1: Read possible for Inverter
parameters (data can be stored in
EEPROM).
