<1> Sets analog input terminals A1, A2, and A3 to supply the speed limit, torque reference, or torque compensation. Setting two analog inputs for the
same function will trigger an oPE07 error (Multi-Function Analog Input Selection Error).
Input Value Polarity
The direction of the input values described above depends on the polarity of the Run command and the input value.
Run Command Direction
Forward
Reverse
Example:
• With a Forward run command and a positive torque reference signal the internal torque reference will be positive, i.e., in
the forward direction.
• With a Forward run command and a negative torque reference signal the internal torque reference will be negative, i.e., in
the reverse direction.
When using analog inputs, negative input values can be generated by:
• applying negative voltage input signals.
• using positive analog input signals while setting the analog input bias to negative values so the input value can be negative.
• applying positive voltage input signals and using a digital input that is programmed for H1- oo = 78.
When using MEMOBUS/Modbus communication or a communication option card, only positive input values can be set.
Independent of its input source, the polarity of the torque reference signal can be inverted using a digital input that is
programmed for H1-oo = 78. Use this function to input negative torque reference values when using MEMOBUS/Modbus
or a communication option card.
n Speed Limitation and Speed Limit Bias
The speed limit setting is read from the input selected in parameter d5-03. A bias can be added to this speed limit using
parameter d5-05 while parameter d5-08 determines how the speed limit bias is applied.
