Actual position reset
You can reset the actual position value (
POS ACT PPU) by using the Homing
sequence or manually through parameters.
Homing sequence
The Homing function is used to calibrate the actual position value
PPU to a reference value. You have to do the homing sequence from the EXT1
control location. You have to configure parameter
HOMING SEL PTR to the
homing activation input, homing acknowledgement signal in parameters
HOMING ACK SEL and
HOMING ACK PTR. When the homing signal is active
and the drive is in EXT1, the message “HOMING ACTIVE” is displayed.
The homing reference has to be configured in parameter
HOMING REF. The
sign of the homing reference is only considered when the Start command does not
define the direction.
The Start command can be issued with the EXT1 start/stop control; you have to
decide the direction according to the present position and the homing
acknowledgement signal position
. The homing sequence will be completed
when the homing acknowledge signal gets activated and the drive stops
automatically. The message “HOMING DONE” will be displayed when the homing is
completed.
The actual position will be initialized to the position set in parameter
HOME
POSITION. For initializing the position value via the fieldbus, see application control
word
bit 1 on page
.
Manual reset of actual position
Manual reset of actual position
POS ACT PPU (mm) without running the
homing sequence:
Actual position value 02.21 is defined with par
HOME POSITION (0 mm by
default).
