4.5.2 MCO Digital Inputs Terminal (X57)
Terminal Designation Description
1 Touch probe switch input Input triggered on the rising edge. If this signal goes high when no touch probe target
position is locked, a new touch probe target position is calculated and locked in
memory.
2 Positive hardware limit switch
input Input triggered on the falling edge. Triggers a hardware limit error and the motor is
stopped according to parameter
19-06 Error Behaviour .
3 Negative hardware limit switch
input Input triggered on the falling edge. Triggers a hardware limit error and the motor is
stopped according to parameter
19-06 Error Behaviour .
4 Home reference switch input Active high. Marks the home position in the application.
5 Go to the target position Active high. Upon activation the motor goes to the specified target position. A low
signal interrupts any positioning sequence. Not used in fieldbus mode.
6 Reset home flag Active high. This input clears the home flag. This allows the performance of a 2nd
homing sequence.
7 Reset touch probe position Active high. This input clears the touch probe position flag. The reset is necessary to
carry out a touch probe positioning command to a new target position. Not used in
fieldbus mode.
8 Quick stop Active low. This input activates the Quick Stop function. The motor is stopped according
to the setting of parameter 19-06 Error Behaviour . After that, the electromechanical brake
is always activated when the Quick stop input is activated, regardless of the parameter
19-06 Error Behaviour setting.
9 Go to home position While this input is high the motor executes the homing sequence and no position or
jog operations are carried out. Any homing sequence is interrupted by a low state on
this input. Not used in fieldbus mode.
10 Latch new reference position
index number Active on the rising edge (must be 0 V for at least 1 ms to guarantee edge detection):
Latches reference position 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.

4.5.3 MCO Digital Outputs Terminal (X59)
Terminal Designation Description
1 Homing completed Active high. This output is always high if an absolute encoder is used.
2 Referenced position
reached Active high. This output is set when the target position is reached according to the setting of
parameter
33-47 Size of Target Window .
3 Error occurred Active high. This output is set every time an error occurs. It is cleared every time a successful error
clear is carried out. This output remains high as long as the power recovery function is selected
(parameter
19-08 Power-Recovery ) and active.
4 Reference index bit 0 Mirror of the currently locked-in reference index bit 0. Not used in fieldbus mode.
5 Reference index bit 1 Mirror of the currently locked-in reference index bit 1. Not used in fieldbus mode.
6 Reference index bit 2 Mirror of the currently locked-in reference index bit 2. Not used in fieldbus mode.
7 Reference index bit 3 Mirror of the currently locked-in reference index bit 3. Not used in fieldbus mode.
8 Reference index bit 4 Mirror of the currently locked-in reference index bit 4. Not used in fieldbus mode.
