* Communications error contents are saved until Fault Reset is input.
(Reset is enabled during run.)
Storing Constants [Enter Command]
(can be written only.)
When a constant is written from the PLC by communications, the con-
stant is written to the constant data area on the RAM in the V7 IP65.
The Enter Command is a command to write the constant data on the
RAM to the non-volatile memory in the V7 IP65. This Enter Command
is executed when data, regardlesss of the value, is written to register
number 0900H. With the factory setting, an Enter Command is
accepted only while the Inverter is stopped. By changing constant
n170, an Enter Command can be accepted even while the Inverter is
running.
While the constant is being stored after an Enter Com-
mand was issued, response to the commands or data
input with the keys on the Digital Operator (JVOP-147)
becomes poor. Be sure to take some measures for an
emergency stop by using the external terminals (setting
the external terminal to Run Command priority, or set-
ting the multi-function input terminal to external fault,
External Baseblock or emergency stop).
Maximum number of writing times of the non-volatile mem-
ory used for V7 IP65 is 100,000; do not execute the Enter
Command excessively.
When a constant is changed from the Digital Operator, the constant data
on the RAM is written to the non-volatile memory without the Enter
Command.
