Appendix 3: Safety diagnosis function (Test pulse diagnosis)

This function enables diagnosis of external wiring by pulse signals output from the emergency stop ports
(EXTEMG11, EXTEMG21). Changing parameter TPOEMG allows EXTEMG11 and EXTEMG21 to output
off-pulses regularly. The width of output pulses is always approximately 20 ms. Checking regularly the test
pulses inside the robot controller enables confirming the correct operation of the emergency stop lines.
When using this function, connect emergency stop switches by seeing
Make sure to prevent test pulses of this function from causing faulty operation of peripheral devices.
