COMPUTER LINK FUNCTION
(4) Permissible communication time interval
Set the permissible communication time interval between the computer and inverter.
(If no-communication with the computer persists for more than the permissible time, the inverter will
come to an alarm stop due to time-out error.)

* The data to be entered from the parameter unit is 9999 and that from the computer is 65535 (HFFFF).
REMARKS
1. At power-on (or reset), communication time interval check begins when the first communication is made in the
computer link operation mode.
2. If the parameter setting is changed, checking begins after parameter values are written.
If communication is broken due to signal cable breakage, computer fault etc., the inverter
does not detect such a fault. This should be fully noted.
(5) Waiting time setting
Determines the waiting time till the reply data is transmitted.
