Using Constant Copy Function
Constant Copy Function
The Varispeed V7 standard JVOP-140 Digital Operator can store con-
stants 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 Varispeed V7 and
VSmini 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, PRGM will flash and copy-
ing will continue.
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
