4.8 Pulse/Dir Mode
The
Pulse/Dir Mode
allows you to connect the drive to a
stepper-motor controller
.
The procedure is the following:
1
- Perform the
basic installation procedure (
see cap. 2.5 Basic installation on page 28 )
;
2
- Enable pulse/dir control via software interface:
a- Set the operative mode
6: Pulse/Dir Mode
;
b- Insert the desired torque reference(*) in the window Torque Sat.;
c- Open the "
Position Loop
" window insert into the numerator and denominator of the
Gear
Ratio
, the ratio that allows you to obtain the desired speed in regards to the encoder.
Example: For 4096 pulses/revolution set as in figure(1/4096)
d-
Save data to Eeprom, turn off and on the drive
;
3
- Execute hardware connections between drive and CN
(
see cap. 2.16 Clock/Dir inputs connections
.
(*) 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.
