Digital and Analog Inputs and Outputs
In order that the expressions which determine the total current and the maximum torque developed by the motor
(Section 11.5 TORQUE CONTROL on page 11-7
remain valid, replace P0169, P0170 by P0018 to P0021.
The option 3 (Process Variable) defines the analog input as the PID Regulator feedback signal (E.g.: pressure
sensor, temperature, etc.). Therefore it is also necessary to configure the parameter P0524 (PID Feedback Selection).
When the analog input is at its maximum limit (P0018 to P0021 indicating 100 %), the process variable will also
be at the maximum value (100 %).
The option 4 (PTC – not available for the AI4 input) configures the input for motor temperature monitoring
by means of a PTC type sensor, when it is present in the motor. Therefore it is also necessary to configure one
analog output (AO) as a current source for feeding the PTC. More details of this function are described in the
Section 15.2 MOTOR OVERTEMPERATURE PROTECTION on page
The option 7 (PLC use) configures the signal at the input to be used by the PLC11 board.
