Digital and Analog Inputs and Outputs
- PLC11: This option configures the signal at the DO1 (RL1), DO2 (RL2) and DO3 (RL3) outputs to be used by the
PLC11.
Definitions of the symbols used in the function:
N = P0002 (Motor Speed);
N* = P0001 (Speed Reference);
Nx = P0288 (Nx Speed) – It is a reference point of the speed selected by the user;
Ny = P0289 (Ny Speed) – It is a reference point of the speed selected by the user;
Ix = P0290 (Ix Current) – It is a reference point of the current selected by the user;
Is = P0003 (Motor Current);
Torque = P0009 (Motor Torque);
Tx = P0293 (Tx Torque) – It is a reference point of the torque selected by the user;
PVx = P0533 (PVx Process Variable) – It is a reference point selected by the user;
PVy = P0534 (PVy Process Variable) – It is a reference point selected by the user;
Nt = Total Reference (refer to the figure 13.8);
Hx = P0294 (Hx Time);
F = P0005 (Motor Frequency);
Fx = P0281 (Fx Frequency) – It is a reference point of the motor frequency selected by the user;
