Note: (*) When inverter is powered up (initialization).
In the factory default setting, the inverter is started in local mode
and the key of the HMI-CFW08-P keypad will select the
local/remote mode.
The inverters with dummy panel (without HMI-CFW08-P keypad)
are factory supplied with P220=3.

The description AI1’ as apposed to AI1 refers to the analog signal
after scaling and/or gain calculations have been applied to it.
For factory default setting, the local reference is via the and
keys of the keypad and the remote reference is via analog
input AI1.
The reference value set by the and keys is contained
in parameter P121.
For details of the Electronic Potentiometer (EP) operation, refer to
Figure 6.19.
When option 4 (EP) is selected, set P265 and P266 to 5.
When option 6 (multispeed) is selected, set P264 and/or P265
and/or P266 to 7.
