5.5.3.1 Settings
Follow these points for proper commissioning of the transducer card:
1. Check that the X4 connector has no connection.
2. Plug the transducer connector onto X14.
3. Provide service power to the drive and perform all standard settings (paragraph "Calibration and adjustments“ on page 57
and paragraph "Setting motor parameters“ on page 57).
4. Navigate the drive menu to the “Quick setup → Motor Parameters → Feedback Type " parameter. Use the keys to change
setting and select “Phonic W ". If you cannot select this transducer, see step 6 just ahead to check if the card is working prop-
erly.
5. Scroll through the menu to the parameter “Quick setup → Motor Parameters → Encoder Lines ". Set the number of sinus -
oids/revolution as reported on the plate or technical data of the transducer.
6. Check if the card is compatible and if it has been recognised by moving to the “Diagnostic → Transduc " menu. Board →
Transduc. Board for...." and verify that the wording "Phonic W" is present. If this does not occur, please contact the ALTER
Technical Office for some verifications.
7. Check the amplitude of incremental signals connected on the X14 connector to pins 3, 4, 6, 7 and the connection of the
transducer’s electrical wires by moving to the “Diagnostic → Transduc Board → SinCos signal A and B" and verify that
there is "OK", otherwise perform these verifications:
1. Written “LOW”: check that you've connected the cable from both sides. Check the cable and welding of wires on the
X14 connector at pins 3, 4, 6, 7.
2. Written “HIGH”: check the cable and welding of wires on the X14 connector at pins 3, 4, 6, 7 that are not short-circuited
with other signals.
8. If all previous verifications are positive, autotune of motor parameters can be performed as explained in paragraph "Autotune
for the calculation of optional parameters“ on page 58.
9. At the end of the autotune procedure, the parameters must be stored in order to complete the commissioning of the transducer
card.
5.5.3.2 Phonic wheel input signal range
The signals provided by the phonic wheel are 2 pairs (or sometimes 3 pairs):
1. Channel A:
1.
PA: Sinusoidal signal of the channel A centred to RA channel that must be between 100 mV and 560 mV
pp
measured
compared to RA.
2. RA: Channel A constant reference; it’s a voltage of about 2.5V.
2. Channel B:
