$S: Parameter writing command (with EEPROM writing function)
Received data (Host
→
Amplifier)
Amplifier ID Host ID Command Parameter address Parameter value
・
When the device number set on the amplifier (value of Pr60) matches with the amplifier ID of received
data,
parameter change is executed.
・
When parameter address and parameter value are abnormal, NAK is answered.
・
Set the parameter address at ‘80
□□
’. (‘805C’ for Pr62)
・
Set the parameter value in 4 digits of ASCII code (P1, P2, P3, and P4) which is obtained by conversion
from the data to hexadecimal.
(e.g. 100 = ‘0064’, -100 = ‘FF9C’)
・
NAK is answered while the amplifier detects undervoltage error, and the parameter is not changed.
・
Changed parameter is written to EEPROM by this command. Response may take some time since
EEPROM writing process is required.
・
When run command is executed by I/O while parameter is being written by communication at the same
time, enter the run command after receiving ACK response from the amplifier. The motor runs per the
written parameter.
・
Writing to EEPROM should be requisite minimum.
(EEPROM endurance: approx. 100,000 write cycle.)

$R: Parameter reading request command
Received data (Host
→
Amplifier)
Amplifier ID Host ID Command Parameter address Parameter value
・
Set the parameter address at ‘80
□□
’. (‘805C’ for Pr62). Set the parameter value at ‘0000’.
・
Enter request for sending after execution of this command, parameter value is responded.

#R: Parameter response command
Transmission data (Amplifier
→
Host)
Host ID Amplifier ID Command Parameter address Parameter value
・
When requested parameter address is abnormal, ‘0000’ as parameter value is answered. You should
check parameter address as you requested.
・
When the parameter reading request command is normally completed, the amplifier answers a parame-
ter
value when it receives request for sending.
・
Parameter address which is read out is sent by ‘80
□□
’.
・
Parameter value is sent in 4 digits of ASCII code (P1, P2, P3, and P4) which is obtained by conversion
from the data to hexadecimal.
(e.g. 100 = ‘0064’, -100 = ‘FF9C’)
