Safety-related I/O signals are input/output signals monitored by two systems. These signals are valid for each feed axis and spindle with a built-in safety function, and are used with each monitoring system. Data output from the detector built into each motor is transferred to the CNC through the amplifier. The safety of this path is ensured by using motors and amplifiers specified by FANUC.

A signal is output (via two paths) to the relay used to shut off the power to the motor drive circuit. An error is detected by a MCC off Test. For detection of built-up failures, a MCC off Test needs to be conducted at certain intervals. This MCC off Test is not mandatory when machining is performed with the protection door closed. (The MCC off Test should be performed, before the protection door is open after the certain intervals.)

The following safe-related I/O signals are monitored or output in redundant mode:
- Emergency stop input signal
- Protective door state input signal (Request to monitor for each axis)
- Input signal for selecting safety speed monitoring and safety position monitoring
- Input signal for monitoring the MCC contact state
- Output signal for turning off the MCC (power-down)
- Output signal for position switch
- Output signal for brake control
- User defined safe-related I/O signals
