Motion Wiring Input/Output Description
Motion Signals Input/Output Description Uniqueness
PTO pulse OUTPUT
PTO pulse from the embedded fast output, to be
connected to Drive PTO input.
Not Shared
PTO direction OUTPUT
PTO pulse direction indication, to be connected to
Drive Direction input.
Not Shared
Servo/Drive On OUTPUT
The control signal used to activate/deactivate
Servo/Drive.
This signal becomes Active when MC_Power (on) is
commanded.
Can be shared
with more than
one drive
Lower (Negative) Limit
switch
INPUT
The input for hardware negative limit switch, to be
connected to mechanical/electrical negative limit
sensor.
Not Shared
Upper (Positive) Limit
switch
INPUT
The input for hardware positive limit switch, to be
connected to mechanical/electrical positive limit
sensor.
Not Shared
Absolute Home switch INPUT
The input for hardware home switch (sensor), to be
connected to mechanical/electrical home sensor.
Not Shared
Touch Probe Input
switch
INPUT
The input for hardware touch probe signal, to be
used with Motion MC_TouchProbe and
MC_AbortTrigger function blocks to capture axis
commanded position during the motion path.
Not Shared
Servo/Drive Ready INPUT
The input signal that indicates Servo/Drive is ready
to receive PTO pulse and direction signal from
controller.
No moving function blocks can be issued to an axis
before the axis has this signal ready if this signal is
Enabled in the motion axis configuration or axis
properties page.
Can be shared
with more than
one drive
In-Position signal
(from servo/motor)
INPUT
The input signal that indicates the moving part is in
the commanded position. This signal has to be
Active after the moving part reaches the
commanded position for MoveAbsolute and
MoveRelative function blocks.
For MoveAbsolute and MoveRelative function blocks,
when In_Position is enabled, the controller will
report an error (EP_MC_MECHAN_ERR) if the signal is
not active within 5 seconds when the last PTO pulse
sent out.
Not Shared
Home Marker INPUT
This signal is the zero pulse signal from the motor
encoder. This signal can be used for fine homing
sequence to improve the homing accuracy.
