7.6.2
Using the Host Controller to Perform Emergency Stop Processing and Turn
OFF the Main Circuit
Perform the following wiring to use the host controller to perform emergency stop processing and to turn OFF
the main circuit.
Connect the emergency stop switch to the host controller’s I/O.
(1) Emergency Stop Signal Confirmation
The emergency stop signal must constantly be monitored by the host controller.
(2) Emergency Stop Processing
When the emergency stop signal turns OFF (emergency stop state), perform the following processing.
• Use the INTERPOLATE (34 hex) command to change the target position for feed axes in motion so that
they decelerate to a stop quickly. Set the target positions so that the axes decelerate to a stop at the desired
rate.
• Set both the spindle and feed axes to decelerate to a stop in this way.
• If the servo driver is currently in Speed Control Mode, set the VELCTRL (3C hex) command to 0 and
change the target position for the INTERPOLATE (34 hex) command so that the axes decelerate to a stop at
the desired rate.
• Check to confirm that all axes (spindle and feed) have stopped.
• Use the SV_OFF (32 hex) command to base-block all axes.
• Use the SMON (30 hex) command for all axes.
