Not my machine, belongs to a customer.
Hyundai hit 30s, Siemens 840c, 1ph6167-4nf40 spindle motor, external fan.
External fan appears to be 380v 3ph motor, .8amps. They replaced the old fan, which was running, thinking it might be bad.
KMSSFM is starter for motor.
KARSE is cube relay for solenoid on KMSSM
XCM 11 connector on board where KARSE is mounted
RFT is "spark killer"/surge protector/ line filter attached to output terminals of KMSSFM. Part number: 3CRH-30330/3CRH-50270
. ................................KARSF ........ XCN 11
Control circuit AC--------5-| |---3-----<<--------------KMSSFM
(3316) (12)

RFT 6
1. Spindle fan does not run until spindle is turning. Is this normal?? (all my Fanucs run the fan when main disconnect is turned on.)
2. After spindle runs for a few minutes, it stops and error message of "spindle fan overload/ overheat". The heater on the KMSSFM has tripped and the RFT6 has gotten to hot to touch. In fact, the old one melted down. Will removing the RFT 6 from the circuit cause the fan motor to be damaged??
3. What is (3316) with KARSE referring to?? The circuitry that powers the relay? Ladder position? It doesn't appear to be a location in the wiring schematic.
Any help would be greatly appreciated.
