4.4 Analog Torque
The drive
can control a motor by using an
analog torque reference
.
The procedure is the following:
1
- Perform the
basic installation procedure (
see cap. 2.5 Basic installation on page 28 )
;
2
- Use pins
An.IN Ref. Torque
to
apply the desired
torque
reference
the axis card used in the
Numerical Control or PLC can have common mode types of analog reference outputs:
•
Common mode reference analog output:
The formula for determining the voltage value to be applied in
An.IN Ref. Torque
in order to obtain
the necessary current is as follows:
V
REF
= 10 * (+/-) I desired
I peak
3
- Execute the
settings of the offset of the velocity analog input reference
via software interface:
•
Open the "
Analog Inputs
" window run
AutoOffset
.
4
- Enable analog torque control via software interface:
a- Set the operative mode
2:Analog Torque
;
b- It is possible to limit the max torque by setting the % of Imax by the value Torque Sat.(the
value 0,0% disable this function)(*).
