2.2 Functions
2.2.1 Screen settings
Contrast, monitor type, foreground language, and display resolution to take effect after
system startup can be set in the operator panel machine data.
Contrast
MD9000 $MM_LCD_CONTRAST (contrast)
For slimline operator panels with a monochrome LCD, the contrast to be applied following
system startup can be set.
There are 16 different contrast settings (0: dark, 15: light).
Monitor type
MD9001 $MM_DISPLAY_TYPE (monitor type)
Indicate the relevant monitor type for optimum color matching.
Foreground language
MD9003 $MM_FIRST_LANGUAGE (foreground language)
On SINUMERIK 840D/840Di/810D, 2 languages are available simultaneously. The
foreground language can be used to set the language to be displayed following control ramp-
up.
The language can be changed in the DIAGNOSTICS operating area on the HMI user
interface. Once the control has ramped up, the foreground language will be restored.
Display resolution
MD9004 $MM_DISPLAY_RESOLUTION (display resolution)
The number of places after the decimal point for the position display of the axes is defined in
the display resolution. The position display consists of max. 12 characters including sign and
decimal point. The number of digits after the decimal point can be set to between 0 and 5.
The default setting for the number of digits after the decimal point is 3, corresponding to a
display resolution of 10–3 [mm] or [degrees].
REFRESH suppression
MD10131 $MN_SUPPRESS_SCREEN_REFRESH (screen refresh in case of overload)
Default setting for screen-refresh strategy with high NC utilization:
• Value 0: Refresh of current values is suppressed in all channels.
• Value 1: Refresh of current values is suppressed in time-critical channels.
• Value 2: Refresh of current values is never suppressed.
