Parameterizing the

PLC basic
program FB1

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".
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
MCPIn:=P#I0.0
MCPOut:=P#Q0.0
MCPStatRec:=P#Q12.0
