A
A = ( Fr1 or Fr1b + SA2 + SA3 - dA2 - dA3 ) x MA2 x MA3
•
If SA2 , SA3 , dA2 , dA3 are not used, they are set to 0.
• If MA2, MA3 are not used, they are set to 1.
•
A is limited by parameters "Low speed" LSP and "High speed" HSP .
• In the multiplication the signal at MA2 or MA3 in % is captured. 100% corresponds to the maximum value of
the corresponding input. If MA2 or MA3 are sent by the communication bus or the graphic display terminal,
a multiplication variable MFr ( see "With graphics terminal: Internal inverter states and values" on page 136 )
must be sent via the bus or the graphic display terminal.
• The inversion of the direction of rotation in the case of a negative result can be locked ( see "Control para-
meters (Fr1 - CHCF)" on page 192 )
