5-7 Programmable analog input function (PAI)
5-7-1 Types of analog inputs
The VAT2000 includes as standard three analog inputs to terminals FSV, FSI and AUX. Each analog
input can be connected to the internal setting signals shown in Table 5-5 by using the programmable
input function.
By connecting an analog interface option (type: U2KV23AD0), the programmable input terminals can be
expanded to up to six channels.

Speed setting 1
Speed setting 2
Speed setting 3
0~100%
This is the speed setting.
The (+) polarity is forward run, and the (-) polarity is the
reverse run settings.
When the speed setting by analog signal is enabled,
then setting 1,2,3 may be selected with the sequence
input functions (VFS, IFS,AUX).

This allows bias setting (C) to ratio interlock function
using an analog input.

0~100%
0~100%
This allows center frequency setting for traverse
operation, using an analog input. The positive polarity is
the forward run, and the negative polarity the reverse
run.

PID feedback
0~100%
0~100%
This is used for feedback signal to the PID function,
using external sensor.
Do not use the PID for speed control
Do not use the programmable analog output (FM, AM)
as PID’s feedback signal.
−
300~300%
Torque setting
0~300%
0~100%
This is the analog setting for torque control.
The (+) polarity is the forward direction torque, and the
(–) polarity is the reverse direction torque. The torque
setting can be limited by using the torque limiter
function (A11-2, 3).

Drive torque
limit reduction
setting
0~100%
0~100%
The drive torque limit (A10-3 or A11-2) may be reduced
in percentage using an analog input. For example using
a signal of 0V to +10V the limit torque is reduced from 0
to 100%
This function is enabled when LIM1, is ON.

0~100%
0~100%
The regenerative torque limit (A10-4 or A11-3) may be
reduced in percentage using an analog input.
This function is enabled when LIM2 is ON.

setting
0~300%
0~300%
A torque bias signal during either speed or torque
control is allowed using an analog input.
This is enabled when the torque bias function TRQB1,
is ON..
(Note 1) FSV, FSI, AUX inputs and modes are selected with C12-0 to 2.
(Note 2) AUX: The setting is limited to 0% during the
−
10 to 0V and
−
5 to 0V input.
