NJ-series CPU Unit Motion Control User’s Manual (W507)
Single
axes
Auxiliary
functions
for single-
axis control
Resetting axis errors
Axis errors are cleared.
Homing
The motor is operated to determine the home using the limit
signals, home proximity signal, and home signal.
High-speed homing
The axis returns to home using an absolute position of 0 as
the target position.
Stopping
The axis is forced to stop.
Immediate stop
The axis is stopped immediately.
Setting override factors
The target velocity for an axis is changed.
Changing the current
position
The command current position or the actual current position
is changed as required for an axis.
Enabling external
latches
The position of an axis is recorded when a trigger occurs.
Disabling external
latches
The current latch is disabled.
Zone monitoring
The system determines if the command position or actual
current position of an axis is within a specified zone.
Axis following error
monitoring
The following error between the command positions or actual
positions of two specified axes is monitored to see if it
exceeds the allowed value.
Following error counter
reset
The error between the command current position and the
actual current position is set to zero.
Torque limit
The output torque is limited by enabling and disabling the
torque limit function of the Servo Drive and by setting the
torque limit value.
Axes
groups
Multi-axes
coordi-
nated con-
trol
Absolute linear interpo-
lation
An absolute position is specified and linear interpolation is
performed.
Relative linear interpola-
tion
A relative position is specified and linear interpolation is per-
formed.
Circular 2D interpolation
Circular interpolation is performed for two axes.
Auxiliary
functions
for multi-
axes coor-
dinated
control
Resetting axes group
errors
Axes group errors and axis errors are cleared.
Enabling an axes group
An axes group is enabled.
Disabling an axes group
An axes group is disabled.
Stopping an axes group
All axes in interpolated movement are decelerated to a stop.
Immediately stopping an
axes group
All axes in interpolated movement are stopped immediately.
Setting axes group over-
ride factors
The blended target velocity is changed during interpolated
movement.
Com-
mon
items
Cams
Setting cam table prop-
erties
The end point index of the cam table that is specified in the
input parameter is changed.
Saving cam tables
The cam table that is specified in the input parameter is
saved to non-volatile memory in the CPU Unit.
Parameters
Writing MC settings
Some of the axis parameters or axes group parameters are
overwritten temporarily.
