Chapter 5 CONFIGURING INVERTER'S FUNCTION CODES FOR CC-Link
COMMUNICATION
Before starting CC-Link communication between the inverter equipped with this option and the CC-Link 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.

Select a response mode to apply when a
communications link error or an option failure is
detected.
o28

Operation timer to apply when
a CC-Link communications
error occurs
0.0 to 60.0 sec.
Specify the timer period during which the
inverter keeps running even if a communications
link error is detected.

*1 For details about the function codes o27 and o28, refer to Chapter 8 "INVERTER REACTION TO CC-Link
COMMUNICATIONS ERRORS."
*2 After changing the o30 data, resetting the option (by turning the terminal RST ON or by turning the option's power
OFF and then ON) validates the new setting. However, resetting the option causes an inverter trip with an alarm
GT
if Version 1.xx is specified on the master station and Version 2.xx on the option.
*3 Changing the o31 or o32 data causes the L.ERR LED to start blinking. Resetting the option validates the new setting
and turns the L.ERR LED OFF.

setting y98 = 3 is
recommended.
*1 In addition to y98, there are some function codes that specify run/frequency command sources. Using those function
codes enables more flexible settings of run/frequency command sources. For details, refer to the description for the
function codes H30 and y98 in the FRENIC-Multi Instruction Manual (INR-SI47-1094-E), Chapter 5 "FUNCTION
CODES."
