SINUMERIK 840D Installation and Start-Up Guide (IAD) – 04.00 Edition
Machine data that specify the coding of compensation values must be set as
follows:
S MD 12000: OVR_AX_IS_GRAY_CODE = 1
S MD 12020: OVR_FEED_IS_GRAY_CODE = 1
S MD 12040: OVR_RAPID_IS_GRAY_CODE = 1
S MD 12060: OVR_SPIND_IS_GRAY_CODE = 1
By default, the following signals are not influenced by the MCP emulation, they
are initialized when the control is started up:
S Keyswitch to position 0
S Spindle speed override to 0
S Rapid traverse overlay to 0
Only “BAGNo” and “ChanNo” parameters are provided for FC 26. For this rea-
son, the user needs to determine the information that is otherwise transferred to
the caller via parameters “FeedHold” and “SpindleHold”.
3.5.2 Standard configuration of the HPU (without MCP)
The standard configuration comprises a SINUMERIK 840D with
MMC100/102/103 and an HPU.
+ The parameter assignment at FB1 for the HHP operating components corre-
spond to those of the 1st MCP:
MCPNum:=1 (one HPU)
MCPIn:=P#I0.0 (HPU input signals)
MCPOut:=P#Q0.0 (HPU output signals)
MCPStatRec:=P#Q12.0 (status double word)
