Preparing for Operation and Monitoring

2-2-2 Outline of Copying Parameters

(1) Check setting of n01
0: Writing from Digital Operator prohibited.
1: Parameters can be changed (default setting).
(2) Clear prohibition of reading the copy function: n77
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: n76
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
different Inverter. Always turn OFF the power supply
before connecting or disconnecting the Digital Operator
to protect against electric shock and product failure.
(5) Perform the write operation for the copy function: n76
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: n76
Verify (vFy) the current parameter settings between the
EEPROM in the Digital Operator and the Inverter.
H Parameters That Cannot Be Copied
1. Copying is not possible between Inverters with different power supply specifications (e.g., from a
100-V Inverter to a 400-V Inverter).
2. The recorded hold output frequency and the following parameters cannot be copied:
n76: Parameter copy and verify function
n77: Parameter read prohibit selection
n78: Error log
n79: Software number
3. The following parameters cannot be copied if the Inverters have different capacities.
n09 to n15: V/f settings
n32: Rated motor current
n46: Carrier frequency selection
