4.13 Square Wave Period
The drive can control a motor by using a
speed digital reference in square wave
.
The procedure is the following:
1
- Perform the
basic installation procedure (
see cap. 2.5 Basic installation on page 28 )
;
2
- Enable digital speed control via software interface
:
a- Set the operative mode
10:Square Wave Period
;
b- Insert the desired speed reference
in Digital Speed
;
c - Insert the desired reversal motor period in Time Delay;
d - Is possible to set the ramp of acceleration and deceleration in the Velocity Loop window;
e- It is possible to limit the torque by setting the % of Imax by the value Torque Sat.(the value
0,0% disable this function)(*).
f-
Save data to Eeprom
;
g- Enable/disable the drive by using the
Enable
/
Disable
buttons or 24V to the
D.IN1
(
ENABLE
) input.

-
If the rotation is irregular or noisy, it should be necessary to
adjust the gains of the
Velocity loop
or
position loop
by using an adequate procedure.
(*) Insert the calculate torque reference using this formula
:
I
desired
x 100
I
peak
Example: Suppose we want to set a digital torque reference equal to 5A, having a drive size of 10/20
(10A=rated current, 20A=peak current)
insert in the window Torque Sat. the value 25, in fact
(5x100)/20=25.
The value 0,0% disable the function.
