îš„ Using Constant Copy Function
 Constant Copy Function
The V7AZ standard JVOP-140 Digital Operator can store constants for
one Inverter. A backup power supply is not necessary because
EEPROM is used.
The constant copy function is possible only for the Inverters with the
same product series, power supply specifications, and control mode (V/
f control or vector control). However, some constants may not be cop-
ied. It is also impossible to copy constants between V7AZ and VS mini
J7 Inverters.
Prohibiting reading constants from the Inverter can be set in n177. The
constant data cannot be changed when this constant is set.
If an alarm occurs when copying constants, will flash and copy-
ing will continue.
To remove the Digital Operator from the Inverter, turn OFF
the input power supply of the Inverter and confirm that the
display on the Digital Operator has turned OFF. If the Digital
Operator is removed while the power is ON, the Inverter may
be damaged.
Constant Copy Function Selection (n176)
Depending on the setting of n176 (Constant Copy Function Selection),
the following functions can be used.
1. Reading all the constants from the Inverter (READ) and storing
them in EEPROM in the Digital Operator
2. Copying the constants stored in the Digital Operator to the Inverter
(COPY)
3. Verifying that the constants in the Digital Operator and the constants
in the Inverter are the same (VERIFY)
4. Displaying the maximum applicable motor capacity and the voltage
class of the Inverter for which constants are stored in the Digital
Operator
5. Displaying the software number of the Inverter for which constants
are stored in the Digital Operator
