Parameters described in this page can be accessed by:
REFERENCE OPERATIONS
Summing input / Subtracting input / Multiplier
A = (Fr1 or Fr1b + SA2 + SA3 - dA2 - dA3) x MA2 x MA3
• If SA2, SA3, dA2, dA3 are not assigned, they are set to 0.
• If MA2, MA3 are not assigned, they are set to 1.
• A is limited by the minimum LSP and maximum HSP parameters.
• For multiplication, the signal on MA2 or MA3 is interpreted as a %. 100% corresponds to the maximum
value of the corresponding input. If MA2 or MA3 is sent via the communication bus or graphic display
terminal, an MFr multiplication variable, page 266 must be sent via the bus or graphic display terminal.
• Reversal of the direction of operation in the event of a negative result can be inhibited (see
[RV Inhibition] (SIn) page 139).
