Machine Terminal
Technical Reference Manual, General
• New language versions:
• English - Swedish
• English - Finnish
• An informative parameter, Config. capacity, added (Main menu/
Configuration/General/Config. capacity). For further
information refer to the Configuration Guideline (1MRS750745-MUM).
• Menu descriptions of virtual I/Os changed to match the names in tools
• 48-hour capacitor back-up for the internal clock of the machine terminal
• Selection of latching feature for the Start LED can be stored in the non-volatile
memory
Function blocks
• Function block revision added (uploading of the function block list to CAP 505)
• Measurement function blocks: outputs indicating the status of warning and alarm
limits added
• Under- and overvoltage protection function blocks UV3_ and OV3_:
• phase-selective start outputs added
• control setting parameter Oper. hysteresis added for adjusting the level
of a comparator (for more information, refer to the CD-ROM Technical
Descriptions of Functions)
• EVENT230 function block: input interface changed
• Changes to input names in the following function blocks: UV3Low, UV3High,
OV3Low, OV3High, MEVO3A, CMVO3
• MEPE7, the function block for power and energy measurement:
• Events for energy (E), apparent power (S), and cos
ϕ added
• Time-based delta event sending added
• Start time range of the MotStart function block changed
from 0.3...80.0 s to 0.3... 250 s
For further information about the above changes, refer to the function block
descriptions on the CD-ROM Technical Descriptions of Functions.
