Instruction manual 91/121 V6.3
Commissioning
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 53
and paragraph ”Setting motor parameters“ on page 54).
4. Navigate the drive menu to the “Quick setup → Motor Parameters → Feedback Type” parameter. Use the keys to change set-
ting and select “EnDat”. If you cannot select this transducer, see the next point to check if the board is working properly.
5. Check if the card is compatible and if it has been recognised by moving to the menu “Diagnostic → Transduc. Board →
Transduc. Board for...." and verify that the word "EnDat" is present. If this does not occur, please contact the ALTER Tech-
nical Office for some verifications.
6. Check the amplitude of incremental signals connected on the X14 connector to pins 3, 4, 6, 7 and the connection of the trans-
ducer’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:
◦
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.
◦
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.
7. Check the correctness of the serial data connected on the X14 connector to pins 10, 12, 15, 23 and the connection of the
transducer’s electrical wires by moving to the “Diagnostic → Transduc Board → Serial comm status" and verify that there is
"OK", otherwise carry out these checks:
◦
Written “FAULT”: check that you've connected the cable from both sides. Check the cable and welding of wires on the
X14 connector at pins 10, 12, 15, 23. Check the connection of the screen to ground on both sides of the cable. The cable
shall be of the braided pair type and the pairs shall be used as indicated in the connection table of the X14 connector.
The length of the cable may not exceed 150 meters.
7. Check for alarms inside the encoder by moving to the “Diagnostic → Transduc Board → Internal alarm status" and verify
that there is "OK", otherwise carry out these checks:
◦
Written “FAULT”: the encoder has internal problems. Replace it with a working one.
8. Check if the encoder is compatible with the board by moving to the “Diagnostic → Transduc Board → Compatible encoder"
and verify that it is written "YES", otherwise carry out these checks:
◦
Written ‘NO’: the encoder isn't compatible. Verify that it has the characteristics indicated at the beginning of the para -
graph.
9. If all previous verifications are positive, autotune of motor parameters can be performed as explained in paragraph ”Autotune
for the synchronization of the transducer“ on page 54.
10. At the end of the autotune procedure, the parameters must be stored in order to complete the commissioning of the transducer
card.
5.5.4 01/333 card for Tacho-generator dynamo transducers
This card makes it possible to control the motor with the following types of transducer:
•
Brushless Tacho-gen Hall sectors (only for brushless motor).
•
Tacho-generator 10V + Hall sectors (only for brushless motor).
•
Tacho-generator d.c. (only for DC motor).
5.5.4.1 D.C. tachometer connection (motor d.c.)
