6.7.6.2 Protection Operation Function Codes
This section describes operation to be performed when communications link errors occur in a state, where
running command or speed command is given via CC-Link, while the inverter is running.
(1) Function code o30 = 0, o31 = 5.00 (Communication error continues for 5 or more seconds, and the
motor coasts to stop)
Figure 6.7.9
(2) Function code o30 = 0, o31 = 5.00 (Communication error continues for 5 or more seconds, and the
motor decelerates to stop)
Figure 6.7.10
*1) For the period until the recovery of communications, the command just before the occurrence of the communications error (run
command and/or speed command) is retained.
*2) During DC braking [DCBRK] or pre-exciting [EXITE] in deceleration to stop, alarm relay output is not performed until the
stop of these commands.
