M-Code Relay Function - NGC

Introduction

This document shows the different ways to set user relay outputs.

The NGC I/O PCB has (x5) user relay outputs. The 8M option has (x8) user relay outputs. These additional outputs can be used to activate probes, auxiliary pumps, or clamping devices. Both of these relays can be operated in two methods:

    Method 1: On/Off with M59 Pnnn/M69 Pnnn

    Method 2: Turn on and Wait for M-Fin with M29 Pnnn (Mills) / M129 Pnnn (Lathes)

M-Code Relays Function Table

This table has the address codes for the 5 User relays on the I/O PCB and three 8M option PCB's installed. As of software version 100.19.000.1400 the M-code relay reset behavior has changed. If more M-codes are needed refer to 8M Installation procedure.

  • User Relay Location - This column gives the physical location of each relay either on the I/O PCB or 8M option PCB
  • Turn On - This column lists the M codes that trigger the relay on.
  • Turn Off - This column lists the M codes that trigger the relay off.
  • Turn On and Wait for M-Fin Signal - This column lists a different set of M codes that trigger the relay on while waiting for a finish signal that triggers the relay off. 
  • Will Turn Off with [RESET], [E-STOP] or ALARM - This column lists how each configuration reacts differently to [RESET], [E-STOP] or an ALARM.

I/O PCB M22 TB3A: 4,5,6 M59 P115 M69 P115 Mills: M29 P115 , Lathes: M129 P115 YES
I/O PCB M23 TB3B: 7,8,9 N/A - Haas Robot Pkg Only¹ N/A - Haas Robot Pkg Only¹ N/A - Haas Robot Pkg Only¹ YES
I/O PCB M24 TB3B: 10,11,12 N/A - Haas Robot Pkg Only¹ N/A - Haas Robot Pkg Only¹ N/A - Haas Robot Pkg Only¹ YES
I/O PCB M25 TB2: 1,2,3 M59 P112 M69 P112 Mills: M29 P112 , Lathes: M129 P112 YES

NOTE: 

  1. User relays M23 and M24 on the I/O PCB are configured from the factory to be used by the Haas Robot Package.  If you do not have the robot option the function of these two relays can use by the user only if the User Relay Kit is purchased.  Refer to User Relay Service Update.

NOTE: 

  1. Behavior of bank 1 (JP1) changes when the “Status Relays” feature is enabled. (Factory Setting 315.26).  For more information on this feature refer to MDC - 8M OPTION STATUS RELAYS.

 NOTE:

  1. For machines built after 2019 without a pallet changer, only outputs P106 through P109 on Bank #2 work. If more outputs are needed, switch Bank #2 to Bank #3 in order to use outputs P79 through P86, but make note that Bank #3 relays do not turn off with [RESET], [E-STOP], or an alarm. Another way to gain spare outputs is to install service kit 93-3913 2ND 8M SPARE NGC ADDON that replaces Bank #2 (spare outputs are restricted on machines with C-APL), refer to the 8M Option - Installation - AD0162 procedure for more information. 
  2. Some factory options, such as Autodoor and APL, use relays from Bank #2 and Bank #4 when enabled. If these options are installed on your machine, the used relays may or may not turn off upon reset.
