4.12 Position feedback connections
The following functions are provided via the 15-way high density D-type
connector on the drive:
• Two position feedback interfaces (P1 and P2).
• One encoder simulation output.
• Two freeze trigger inputs (marker inputs).
• One thermistor input.
The P1 position interface is always available but the availability of the P2
position interface and the encoder simulation output depends on the
position feedback device used on the P1 position interface, as shown in
Table 4-18.

4.12.2 Compatible position feedback devices
Table 4-16 Supported feedback devices on the P1 position interface
* This feedback device provides very low resolution feedback and should
not be used for applications requiring a high level of performance
Table 4-17 Supported feedback devices on the P2 position
interface
Table 4-18 shows the possible combinations of position feedback device
types connected to the P1 and P2 position interfaces and the availability
of the encoder simulation output.
