Set up of Keep Relays on Fanuc 21i Machines for CIM Systems

Q. Setup of I/O on the Fanuc 21i machines in a Denford CIM system

A. The FANUC 21i controllers work in a similar way to the Denford controllers regarding auxiliary inputs and outputs, however various parameters must be set to enable them.

1) ON DENFORD FANUC 21i LATHES
Set Keep Relay 1.1 to 1 use auxiliary 2 for chuck
Set Keep Relay 0.1 to 1 Programmable chuck

2) ON DENFORD FANUC 21i MILLERS
Set Keep Relay 1.1 to 1 use auxiliary 2 for vice
Set Keep Relay 0.0 to 1 Programmable vice

Q. Set up of Fanuc 21i machines in Denford CIM systems

A.
1) ON DENFORD FANUC 21i LATHES
Set parameter 3201, bit 7 to 1 use “MINP” input
Set Keep Relay K1.4 to 1 use “MINP” input
Set parameter 3411 to 15 the M code M15 is not buffered

2) ON DENFORD FANUC 21i MILLERS
Set parameter 3201, bit 7 to 1 use “MINP” input
Set Keep Relay K1.4 to 1 use “MINP” input
Set parameter 3411 to 15 the M code M15 is not buffered
