Step:
Set up the PID Controller
In order to set up the PID controller the following parameters have to be set:
J01. PID control (Mode select).
This function is used to setup the operation mode of the PID controller. The
alternatives are:
0
PID
inactive
1
PID active, forward operation
2
PID active, reverse operation
Factory setting is 0.
J02. Remote process command.
This parameter is used to set the source of the Set Value for the PID Controller.
0
Enable set by Keypad
1
PID process command 1
3
Enable terminal command (up)/(down) control
4
Command via communication link
When setting J02 to 1, we have to specify the source of this command. In order to do
so we have to program one of the following functions to 3 (PID process command 1):
E61 to 3 when using terminal 12 (0 to 10V DC)
E62 to 3 when using terminal C1 (4 to 20mA)
E63 to 3 when using terminal V2 (0 to 10 V DC)
The second signal that we have to set is the source of the PID Feedback. This also
will be done using the functions mentioned above, depending on the kind of feedback
signal that the inverter receives from the sensor:
E61 to 5 when using terminal 12 (0 to 10V DC)
E62 to 5 when using terminal C1 (4 to 20 mA)
E63 to 5 when using terminal V2 (0 to 10V DC)
