Chap. 2
FUNCTION C
O
DES
y97 Bus function (Mode selection) (Refer to H30)
The inverter memory (non-volatile memory) has a limited rewrite times (100 thousand to 1 million
times). If the count immoderately increases, the data cannot be modified or saved, causing a memory
error.
If the data should frequently be overwritten via communication, it can be written in the temporary
memory instead of the non-volatile memory. This allows to reduce the rewrite times to the
non-volatile memory, which can avoid a memory error.
If y97 is set to “2”, the data written in the temporary memory is stored (All Saved) in the
non-volatile memory.
To change the y97 data, it is necessary to press the
+
/
keys (simultaneous keying).
y97 data Function
0
Store into nonvolatile memory (Rewritable times are limited)
1
Write into temporary memory (Rewritable times are unlimited)
2
Store all data from temporary memory to nonvolatile memory
(After storing all data, the y97 data returns to 1)
y99 Loader Link Function (Mode)
This is a link switching function for FRENIC Loader. Setting the function code data y99 with the
loader enable the loader to issue control commands and/or run commands to the inverter. Since the
data setting can be done with the loader, no keypad operation is required.
While the loader is selected as the source for the run command, if the PC runs out of control and
cannot be stopped by a stop command sent from the loader, disconnect the RS485 communications
cable from the loader's port, connect a keypad instead, and reset the y99 to "0." This makes that the
control and run commands are generated according to function code H30 setting, as shown in the
table below.
Note that the inverter cannot save the setting of y99. When the inverter is turned off, the data in y99
will revert to "0."
