9 Motion Control Functions
9-66
NJ-series CPU Unit Motion Control User’s Manual (W507)
The output torque is limited by enabling and disabling the torque limit function of the Servo Drive and by
setting the torque limit value.
Different limits can be specified for the positive torque limit and negative torque limit.
For details, refer to the MC_SetTorqueLimit instruction in the
NJ-series Motion Control Instructions Ref-
erence Manual
(Cat. No. W508).
Latching is used to control positioning based on the position where a trigger signal occurs, such as a
signal from a sensor input. The position of the axis is recorded (i.e., latched) when the trigger signal
occurs. You can set up to two trigger signals for each axis. Use the MC_TouchProbe (Enable External
Latch) instruction to specify the trigger input condition, a window, and the stop method for the axis you
want to latch. In addition to signals that connect to the Servo Drive, you can also specify variables in the
user program to use as a trigger. Use the MC_AbortTrigger (Disable External Latch) instruction to abort
latching. You can use latching only with a Servo Drive that support latching (touch probe), such as the
G5-series Servo Drives, or a GX-EC0211/EC0241 Encoder Input Terminal.
Use
WindowOnly
to detect only trigger signals within a specific start point and end point. The following
chart shows the ranges for different Count Modes.

•
The
FirstPosition
must be less than or equal to the

•
An instruction error will occur if the
FirstPosition
is greater than the
LastPosition
.
•
An instruction error will occur if a position beyond the position range of Linear Mode is specified.
