4.10 Homing - Example
Example:
Homing sequence
Suppose to do the homing method: "
3 : Clockwise home switch (NO) and index pules
". The pro-
cedure is the following:
1- Select the desired operative mode.
2- In the "Homing" window of the interface set the desired homing method and its parameters.
Save all to the Eeprom.
3- Open the “
Digital Input/Outputs
” window and set:
- A digital programmable input with the
"Start Homing"
function (for example:
DGT-IN2
);
- A digital programmable input with the
"Homing Sensor"
function (for example:
DGT-IN3
);
- A digital output with the
"Homing OK"
function (for example:
DGT-OUT1
);
Save all to the Eeprom.
4- Execute the homing procedure:
a- Enable the
DGT-IN1
(
Enable
) digital input
the motor will be on torque.
b- Enable the
DGT-IN2
(
Start Homing
) digital input
the motor moves to search the home po
-
sition using the homing parameters saved on the interface. Every time this input is disabled the
homing position is resetted.
c- When the home sensor output, connected to the
DGT-IN3
(
Homing Sensor
) digital input, is
sensed active (in this example we considered a normally opened sensor), the motor decelerates
and inverts its motion.
d- The home position is set when the falling edge of home sensor is received. When this happens
the drive enables the
DGT-OUT1
(
Homing OK
) digital output. This value is kept high as soon as
the
DGT-IN2
(
Start Homing
) digital input is kept high, independently of the
DGT-IN1
digital in
-
put (see (B) in the figure).
