Designation Description
Touch probe switch Interrupt triggered on the rising edge. If this signal
input goes high when no touch probe target position is
currently locked a new touch probe target position
is calculated and locked in memory.
Positive HW limit Interrupt triggered on the falling edge. Triggers a
switch input HW limit error and the drive is stopped according to
P1906.
Negative HW limit Interrupt triggered on the falling edge. Triggers a
switch input HW limit error and the drive is stopped according to
P1906.
HOME reference Active high. Marks the HOME position in the appli-
switch input cation.
Go to the refer- Active high. Upon activation the drive goes to the
enced target posi- specified target position. A low signal interrupts any
tion positioning sequence. Not used in fieldbus mode.
Reset home flag Active high. This input clears the home flag. This al-
lows the user to perform a second homing se-
quence. Not used in fieldbus mode.
Reset touch probe Active high. This input clears the touch probe posi-
position tion flag. The reset is necessary to carry out a touch
probe positioning command to a new target posi-
tion. Not used in fieldbus mode.
Quick stop Active low. This input activates the Quick Stop func-
tion. The drive is stopped according to the setting of
P1906. After that the electromechanical brake is al-
ways activated when the "Quick stop" input is acti-

Go to HOME posi- While this input is high the drive executes the hom-
tion ing sequence. While this input is high no position or
jog operations are carried out. Any homing se-
quence is interrupted by a low state on this input.
Not used in fieldbus mode.
LATCH new refer- Active on the rising edge (must be "0" min. 1 ms. to
ence position index guarantee edge detection): Latches reference posi-
number tion index number specified on terminal 18, 19, 29,
32, 33 into memory. Digital output 4 – 8 is changed
to mirror the new reference index specified when
using digital input control. Not used in fieldbus
mode.
