These parameters are communication parameters that are not cleared when parameter clear (All
parameter clear) is executed from Ethernet network (MODBUS®/TCP or CC-Link IE Field Network
Basic).
(Refer to page 6-333 for the details of the MODBUS®/TCP, and page 6-349 for the details of the CC-
Link IE Field Network Basic.)

Ethernet TCP disconnection
time coefficient
1 3600 1–7200
When the inverter does not receive a packet
within the time calculated by multiplying
the Pr. 850 setting by 8 in seconds from the
devices with the TCP connection established,
the connection will be forcibly closed.

Set the interval of the communication check
(signal loss detection) time for all devices
with IP addresses in the range specified for
Ethernet command source selection (Pr. 844
to Pr. 849). If a no-communication state
persists for the permissible time or longer,
the inverter output is shut off.

bus voltage level is set to low, overvoltage
error will be less apt to occur. However, the
actual deceleration time increases.
The set value must be higher
than the "power supply
