ENTER Command (Write-only Register)
When writing a constant from the master through communications,
always execute the ENTER command after changing the constant.
When a constant is changed, the new value is written to the constant
data area in the Inverter’s RAM. The ENTER command writes the con-
stant data from RAM to the non-volatile memory in the Inverter. The
ENTER command can be executed by writing data to register number
0900H while the Inverter is stopped.
Since the Inverter’s EEPROM can be overwritten a limited number of
times (100,000 times), do not execute the ENTER command too fre-
quently. When two or more constants are being changed, execute the
ENTER command once after changing all of the constants.
While the constant is being stored after an ENTER
command was issued, response to the commands or
data input with the keys on the Digital Operator
(JVOP-140) becomes poor. Be sure to take some mea-
sures for an emergency stop by using the external ter-
minals (setting the external terminal to run command
priority, or setting the multi-function input terminal to
external fault, external baseblock or emergency stop).
