13. FUSES
The servo drive (DRIVER) cards have three fuses on each of the X, Y, Z, and A PCBs (F1, F2, F3). If these fuses are ever
blown, the associated motor will stop. This will only happen if there is a failure of the drive card and the user should never
attempt to replace these fuses.
The POWER PCB contains three ½-amp fuses located at the top right (FU1, FU2, FU3). If the machine is subject to a severe
overvoltage or a lightning strike, these fuses will blow and turn off all of the power. Replace these fuses only with the same
type and ratings. The other two fuses protect the tool changer (FU5) and the operators lamp (FU6).
On the servo drive assembly, there is a printed circuit board (SDIST) containing three one-amp fuses (FU1, FU2, FU3). Two
of these fuses protect the contactor and small transformers. They are never expected to blow. The third fuse protects the
regen load circuit load from shorts.

14. SPARE USER M CODE INTERFACE
The M code interface uses outputs M21-24 and one discrete input circuit. M codes M21 through M24 will activate relays
labled M21-24. These relay contacts are isolated from all other circuits and may switch up to 120V AC at one amp. The
relays are SPDT.
WARNING! POWER CIRCUITS AND INDUCTIVE LOADS MUST HAVE SNUBBER PROTECTION.
The M-FIN circuit is a normally open circuit that is made active by bringing it to ground. The one M-FIN applies to all eight
of the user M codes.
The timing of a user M function must begin with all circuits inactive, that is, all circuits open. The timing is as follows:
The Diagnostic Data display page may be used to observe the state of these signals.
14.1 M FUNCTION RELAYS
The IOPCB contains position for four relays (M21-M24) and all are available to the user. In addition, M21 is already wired
out to P12 at the side of the control cabinet. This is a four-pin DIN connector and includes the M-FIN signal.
