After setting the drive to STOP and opening the reserved parameter key (P60=95), set C41=1 to
enable the test. To start the test enable RUN command.
Once the test has started the motor will rotate in the positive direction at low speed and some
measure are done on Resolver signals.
During the test, the motor will make a complete revolution at low speed.
Do not worry if this revolution is a little noisy.
In the first step is checked if the cyclic sense of motor phases and Resolver channels is the same:
after 1 second parameter P79 is updated with the pulses number counted (there are 65536 pulses
every turn/Resolver polar couples) and the drive consequently goes in alarm A14 or it starts the
second test:
o P79<0 : meaning that Resolver channels are exchanged, therefore A14 code 0 is
triggered
o P79>0 : everything is ok
In the second part is checked the Resolver channels reading, well known that current test frequency
is 0,5Hz the time needed for read again the same Resolver position is equal to:
number couplepolar Resolver
number couplepolar Motor
2 testtime ⋅=
[seconds]
At the end of the test, P79 is updated again with the time test measured in ms:
o |P79- time test| < 500ms : test is successful
otherwise the alarm A15 code 3 is triggered. In the first check if it is correct the Resolver poles
number and the number of motor poles, with help of P79.
The test is successful if the drive switch off and does not trigger an alarm. Now disable RUN
command by setting its digital input to 0. The subsequent tests can now be carried out.
2.1.4.5 INCREMENTAL SIN COS ENCODER
2.1.4.5.1 SENSOR PARAMETERS
It’s necessary to have set correctly the parameter P69
2.1.4.5.2 SPEED SENSOR TEST
. It is in two parts:
o Check that the direction of rotation of the motor phases and the Encoder
correspond;
o Check that the number of motor poles is written correctly in parameter P67 and the
Encoder used is correctly define as pulses per revolution with parameter P69
Correct operation requires a no-load motor so decouple it from the load.
After setting the drive to STOP and opening the reserved parameter key (P60=95), set C41=1 to
enable the test. To start the test enable RUN command.
Once the test has started the motor will rotate in the positive direction at low speed and all Encoder
edges are counted.
During the test, the motor will make a complete revolution at low speed.
Do not worry if this revolution is a little noisy
In the first step is checked if the cyclic sense of motor phases and Encoder channels is the same:
