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. frequency
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 frequency 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.)
