Positioning Drive Setup Ver. 0002 PSU - 15

PSU.9 STARTUP SUMMARY

General parameters

AP1: Selects the operating mode of the drive.

= 3: Position loop using motor feedback without Feedforward.

= 4: Position loop using direct feedback without Feedforward.

= 11: Position loop using motor feedback with Feedforward. (PP216)

= 12: Position loop using direct feedback with Feedforward. (PP216)

GP10: Direct feedback signal type.

= 0 There is no direct feedback.

= 1 Square TTL signal

= 2 "1Vpp" sinewave signal or differential square TTL signal.

Check the value taken by the parameter:

GP2: Motor feedback type.

= 0 Sinewave encoder

= 1 Resolver.

= 2 Squarewave TTL encoder.

= 5 Heidenhain encoder (ERN 1387) for Siemens motors, 1FT6 family.

When using motor feedback (AP1=3 or AP1=11)

The following parameters are ignored:

GP10: Direct feedback signal type.

PP54: Refvalue with direct feedback.

PP115: Direct feedback parameter setting.

NP117: Pitch/pulses setting for direct feedback.

When using external feedback (AP1=4 or AP1=12)

The following parameters are ignored:

PP150: Refshift for motor feedback.

PP52: Refvalue with motor feedback.

Resolution related parameters:

PP115: External feedback parameter setting.

Bit 5: Structure of distance coded feedback

= 0 counting positive with positive direction

= 1 counting negative with positive direction

Bit 3: Direction polarity

= 0 not inverted

= 1 inverted

Bit 1: Feedback type

= 0 rotational feedback. See NP117.

= 1 lineal. See NP118.

Bit 0: Direct feedback type:

= 0 Rotary (encoder), (NP117 will give pulses per turn).

= 1 Linear (scale), (NP117 will give the period of the scales feedback signal).

NP117: Resolution of the rotary direct feedback in pulses per turn.

NP118: Resolution of the linear direct feedback.

- period of the scale signal. 20 microns for Fagor scales (graduated glass), S118 = 20 microns.

NP121, NP122: The "NP121/NP122" ratio indicates the gear ratio between the motor and the ballscrew.

They only admit integer values up to 32767.

NP123: Ballscrew pitch. If it is a rotary axis, set NP123 = 360000.

Parameters to identify a linear feedback with distance-coded reference marks:

NP165: Distance between reference marks.

NP166: Distance between "coded" reference marks.
