 The hot line forced stop function is enabled at the MR-JE-B factory-set. (Only MR-JE-B)
 This function is used to execute deceleration stop for all axes by outputting the hot line forced
stop signal to all axes and generating "E7.1" (Controller forced stop input warning) at the
alarm occurrence.
 This function can be disabled by the servo parameter (PA27).

For using the MR-JE-B, configure up the power supply circuit which switches off the all axes
electromagnetic contactor (MC) from the CPU module after detecting the alarm occurrence
on the CPU module.
