Note 1. The n68 to n74, n76, and n77 parameters cannot be written via RS422/485 communications.
They are read-only.
Note 2. Motor parameters depend on the Inverter capacity as shown in the following table.

Description
Select whether or not to enable the RTS
(request-to-send) communications control
function.
Used to select a function to reduce the carrier
frequency when Inverter is at low speed.
0: Function disabled

rED: Reads the Inverter parameters.
Cpy: Copies the parameter to the Inverter.
vFY: Verifies the Inverter parameters.
vA: Checks the Inverter capacity display.
Sno: Checks the software number.
Selects the copy-prohibit function.
Use this parameter to protect the data in the
EEPROM of the Digital Operator.
0: Read prohibited for Inverter parameters.
(Data cannot be written to EEPROM.)
1: Read possible for Inverter parameters.
