<1> Sets analog input terminals A1, A2, and A3 to supply the speed limit, torque reference, or torque compensation. An oPE07 error
(Multi-Function Analog Input Selection Error) will occur if two analog inputs are set for the same function.
Input Value Polarity
The direction of the input values described above depends on the polarity of the Run command and the input value.
• 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 analog inputs are used, negative input values can be generated by
• applying negative voltage input signals.
• using positive analog input signals but setting the analog input bias to negative values so that the input value can be
negative.
• applying positive voltage input signals and using a digital input that is programmed for H1- = 78.
When MEMOBUS/Modbus communication or a communication option card is used, only positive input values can be
set.
