Positioning Drive Setup Ver. 0002 PSU - 3

PSU.2 DIRECT FEEDBACK

The position feedback may be mounted directly on the moving load. From now on, this will be

referred to as "Direct Feedback".

To work with direct feedback,

- Take the signal to connector X3 of the drive.

- activate bit 2 of parameter AP1 -S32-.

- indicate to the Drive the type of feedback device and the type of signal using these

parameters:

GP10 -F234- Feedback2Type

NP117 -S117- ResolutionOfFeedback2

PP115 -S115- PositionFeedback2Type

To work with motor feedback,

- take the signal to connector X4 of the drive.

- deactivate bit 2 of parameter AP1 -S32-.

- indicate to the Drive the type of feedback device and the type of signal using these

parameters:

GP2 -F701- Feedback1Type

In order for the drive to know the mechanical ratio between the motor movement and the direct

position feedback, set the following parameters:

NP121 -S121- InputRevolutions

NP122 -S122- OutputRevolutions

NP123 -S123- FeedConstant

Example:

Diameter of the output pulley = 25.75 mm

Diameter of the input pulley = 15.3 mm

NP121 = 2575

NP122 = 1530

Gear ratio =2575/1530 =1.683

Ballscrew pitch = 5 mm

NP123 = 5 milimeters
