Terminal
AO1-GND
AO2-GND
F5-07 and F5-08 define how AO terminals indicate the drive internal running parameters in
analog mode.
It is possible to change sense, offset and scaling of parameters on analog outputs. This is by
correcting outputs according to the following formula:
Y = kX + b,
Where:
● Y = output parameter after correction.
● X = output parameter before correction.
● k = scaling factor set by F5-11.
● b = offset set by F5-10.
Note that scaling and offset values can be positive or negative.
Use of PG Terminal
The FVC mode with sensor, set by function code F0-01 = 1, helps to improve stability and
accuracy of motor speed control. In this case it is necessary to install an encoder on motor to
provide sensor input to PG card that the drive requires.
There are four versions of PG card to support different encoder types:
● Differential encoder
7
● UVW encoder and wire-saving UVW encoder
● Resolver
● Open-collector encoder
Settings of encoder parameters F1-27 and F1-28 depend on type of encoder used with the drive.
The following table describes function code settings for each of encoder types.

Input Signal Characteristic
If J5 jumps to the "V" position, AO outputs voltage signal of 0 to 10 VDC.
If J5 jumps to the "I" position, AO outputs current signal of 0 to 20 mA.
It outputs voltage signal of 0 to 10 VDC or current signal of 0 to 20 mA.
