Description
Used to the set the unit of frequency reference and
frequency-related values to be set or monitored
through communications.
0: 0.1 Hz
1: 0.01 Hz
2: Converted value based on 30,000 as max. fre-
quency
3: 0.1% (Max. frequency: 100%)
Used to set the Slave address (Slave unit number)
for communications.
0: Only receives broadcast messages from
the Master.
01 to 32: Slave address
Used to set the baud rate for communications.
0: 2,400 bps
1: 4,800 bps
2: 9,600 bps
3: 19,200 bps
Used to set the parity for communications.
0: Even parity
1: Odd parity
2: No parity
Used to set the waiting period for returning a
response after the DSR (data-send-request) mes-
sage is received from the Master.
Select whether or not to enable the RTS (request-to-
send) communications control function.
Used to select a function to reduce the carrier fre-
quency when Inverter is at low speed.
0: Function disabled
1: Function enabled
Note Normally set n75 to 0.
Selects the function to read, copy, and verify the
parameter between the memory of the Inverter and
that of the Digital Operator.
rdy: Ready to accept the next command.
rED: Reads the Inverter parameter.
Cpy: Copies the parameter to the Inverter.
vFY: Verifies the Inverter parameter.
vA: Checks the Inverter capacity display.
Sno: Checks the software number.
Select 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. (Data can
be written to EEPROM.)
