Chapter 5 CONFIGURING INVERTER'S FUNCTION CODES FOR DeviceNet
COMMUNICATION
Before starting DeviceNet communication between the inverter equipped with the communications card and the
DeviceNet master device, configure the inverter's function codes listed in Table 5.1.
Table 5.2 lists other related function codes to be configured if necessary.

If there is no special
problem with your
system, setting y98 =
3 is recommended.
*1 After configuring the function code o31 or o32, restart the inverter to validate the new settings. For details about these
function codes, refer to Chapter 7 "I/O MESSAGE."
Input and output assembly instances should not be necessarily set to the same instance type. (Ex. Output assembly
instance = Extended speed control output, Input assembly instance = User defined assembly input.)
*2 If the extended speed control output is selected (o31 = 0 or 21), only bit operation in the instance can select the
run/frequency command sources, so no prior configuration of y98 is required. For details, refer to Section 7.2.2
"Extended Speed Control Instance."
