Rising edge of encoder DI1 (proximity switch signal) is detected at the first mark
of the belt. Position 0 mm is stored to signal 4.03 PROBE1 POS MEAS.
Falling edge of encoder DI2 (proximity switch signal) is detected at the second
mark of the belt. Position 40 mm is stored to signal 4.04 PROBE2 POS MEAS.
The reference distance between the marks is 60 mm and the measured distance
between the marks is 40 mm, thus the error is 20 mm:
(62.18 PROBE2 POS - 62.16 PROBE1 POS) - (4.04 PROBE2 POS MEAS - 4.03
PROBE1 POS MEAS)] = (60 - 0) - (40 - 0) = 20 mm
Note: Only after the active correction is finished is the next position latching enabled.
Emergency stop
Note: The user is responsible for installing the emergency stop devices and all the
additional devices needed for the emergency stop to fulfil the required emergency
stop category classes.
The emergency stop signal is connected to the digital input which is selected as the
source for the emergency stop activation (parameter 10.10 EM STOP OFF3 or 10.11
EM STOP OFF1). Emergency stop can also be activated through fieldbus (2.12 FBA
MAIN CW).
Note: When an emergency stop signal is detected, the emergency stop function
cannot be cancelled even though the signal is cancelled.
