STOPPED
This parameter will only become visible if an induction motor is selected, Control Strategy is set to Vector Control, and the drive is an
AC30P/D
The parameter selects between encoder inputs :
MAIN SPD FEEDBACK : encoder option fitted
SYSTEM BOARD SLOT 1 : encoder connected on SLOT1 if AC30D
SYSTEM BOARD SLOT 2 : encoder connected on SLOT 2 if AC30D
NONE : no encoder connected – corresponds to SENSORLESS control selected
If Control Type is set to SENSORLESS, selecting MAIN SPD FEEDBACK or SYSTEM BOARD SLOT 1 or SYSTEM BOARD SLOT 2
has no effect and will not give any warning or trip.
If an encoder is available, encoder feedback control would normally be the preferred choice as it gives better speed control and higher
performance.
Functional Description
The motor selection is the first step in setting the control mode.
The selection of control strategy comes next, with the permitted settings as follows:
- Induction motors can be run in either volts hertz mode or vector mode
- Permanent magnet motors can only be run in vector control mode
If an induction motor is selected, vector control is selected, and an encoder option is fitted, it is then necessary to choose whether to select vector
control with encoder feedback for improved performance.
