14.3 Motion Control
14-65
The following figure explains how to read major machine data.
Fig. 14.3 Positioning timing
• MD30330 MODULO_RANGE (For each axis)
Meaning: Rotation axis motion range
Amount of motion until the position indicator has increased and be reset
to zero (0).
This command can be set to axis positioning control and also to rotation
axis control.
Setting value: [deg]
Standard setting value: 360 deg
14.3.4 Emergency stop
On YS 840DI the emergency stop is activated by the deceleration stop according to CNC
command, as described on the following page.
In this case, after emergency stop, CNC switches over to the speed reference mode for drive
and outputs the deceleration command. When the speed has been fallen to or below
MD36060, CNC outputs the emergency stop command to the drive to stop at the maximum
torque and then to turn off the servo drive. The machine data and parameters related to the
emergency stop are listed below.
