2-2-2 Outline of Copying Parameters
(1) Check setting of n001
0: Writing from Digital Operator prohibited.
1: Parameters n001 through n049 can be changed
(default setting).
4: All parameters can be changed.
(2) Clear prohibition of reading the copy function: n177
This function protects parameters stored in the Digital
Operator.
0: Reading copy function (rEd) prohibited (default setting).
1: Reading copy function (rEd) enabled.
(3) Perform the read operation for the copy function: n176
Read (rEd) the current parameter settings from the Inverter
to the EEPROM in the Digital Operator.
(4) Disconnect the Digital Operator and connect it to a differ-
ent Inverter. Always turn OFF the power supply before con-
necting or disconnecting the Digital Operator to protect
against electric shock and product failure.
(5) Perform the write operation for the copy function: n176
Write (CPy) the current parameter settings from the EE-
PROM in the Digital Operator to the Inverter.
(6) Perform the verify operation for the copy function: n176
Verify (vFy) the current parameter settings between the EE-
PROM in the Digital Operator to the Inverter.
See operation on next page.
Same basic operation as for n001.
Set n001 to 4.
Set n177 to 1.
Set n176 to rEd.
Set n176 to CPy.
Set n176 to vFy.
Change Inverter connection.
Turn ON power after checking
wiring.
H Parameters That Cannot Be Copied
1. Copying is not possible between Inverters with different power supply specifications (e.g., from a
200-V Inverter to a 400-V Inverter).
2. The recorded hold output frequency and the following parameters cannot be copied:
n176: Parameter copy and verify function selection
n177: Parameter read prohibit selection
n178: Fault log
n179: Software number
3. The following parameters cannot be copied if the Inverters have different capacities.
n011 to n017: V/f settings
n036: Rated motor current
n080: Carrier frequency selection
