Hi Everyone!
This machine is capable of using M440-M449 as external outputs. The electrical diagram shows four outputs for each open M code. Ports one and two work as a switch. Port three appears to be a signal wire. Port four is 24V DC out. When testing these ports the machine will always have the 24V out. However, when activating the M code in MDI mode the signal will not reach the corresponding relay. If you can give any information about these M code options and how they work or correct the description given please do.
