6.5.16 HTL Encoder setup
A HTL encoder can be connected to the DI3 and DI4 of the inverter. The encoder can be used for:
As a motor encoder for speed control
As a process encoder as a setpoint (e.g. true web speed for winding application) or as an actual value for e.g.
PID Controller
Setup:
1. Select the encoder in P410:2
2. Set the encoder increment/revolution P341:1
3. Select the function of the encoder:
P600:2 Feedback PID / P201:2 PID setpoint / P201:1 Frequency setpoint
Note: If SC or SLPSM mode is selected the encoder is automatically assigned as feedback.
The actual encoder feedback is displayed in 0x2C42:6
Set the number of increments per revolution of the connected encoder
(See data sheet of the encoder)
0: Digital input
