Change Axis Use MC_ChangeAxisUse The MC_ChangeAxisUse instruction
temporarily changes the Axis Use axis
parameter.
--- Yes
Enable Digital Cam
Switch
MC_DigitalCamSwitch The MC_DigitalCamSwitch instruction
turns a digital output ON or OFF accord-
ing to the axis position.
AYes
Time Stamp to Axis Posi-
tion Calculation
MC_TimeStampToPos The MC_TimeStampToPos instruction
calculates the position of the axis for the
specified time stamp.
AYes
Periodic Axis Variable

Tasks
MC_PeriodicSyncVariables The MC_PeriodicSyncVariables instruc-
tion periodically synchronizes Axes Vari-
ables between tasks.
--- Yes
*1. This instruction functions to enable and disable axis control (i.e., pulse output) for a Pulse Output Unit. It does not turn
the power ON and OFF to the motor that is connected to the motor drive that in turn is connected to the Pulse Output Unit.
*2. When you combine a Pulse Output Unit and the MC Function Module to perform homing, set the Home Input Signal pa-
rameter in the Homing Settings in the MC Function Module to 1 (Use external home input). Also, connect the home input
signal to external input 0 on the Pulse Output Unit and set the External Input 0 Function Selection parameter to latch input
1. Use an external home sensor or the encoder phase-Z signal for the external input signal. Refer to External Input Func-
tion Selection on page 8-65 for details.
*3. This instruction adjusts the command position according to the actual position. It does not manipulate the error counter
reset output from the Pulse Output Unit. This instruction does not reset the accumulated following error in the motor drive
that is connected to a Pulse Output Unit.
*4. This instruction cannot be used together with a Pulse Output Unit. If you execute it, a Process Data Object Setting Missing
error occurs.
*5. This instruction resets an error condition between the MC Function Module and the Pulse Output Unit. It does not reset
the error in the motor drive that is connected to a Pulse Output Unit.
