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 with its digital input.
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:
after 1 second parameter P79 is updated with the test result and the drive consequently goes in
alarm A14 or
it starts the second test:
o
P79=0
: meaning that is missing at least one Encoder channel, therefore A14 code
0 is triggered
o
P79<0
: meaning that Encoder channels are exchanged, therefore A14 code 0 is
triggered
o
P79>0
: everything is ok
In the second part is checked the Encoder pulses reading, well known from P69 parameter the
number of edges in a mechanical turn (P69x4, because are counted both two channels edge).
At the end of the test, P79 is updated again with the total edges number:
o
|P79- (P69x4)|/(P69x4) < 12,5%
: test is successful
otherwise the alarm A15 code 3 is triggered. In the first check if it is correct the
Encoder number of pulses per revolution and the number of motor poles.
o
P79 < (P69x4)
: the real pulses counted are less than expected. Encoder could
have some problems or the motor load is too high. Try to increase the test current
with parameter P114 that is the percentage of rated drive current applied in the test
o
P79 > (P69x4)
: the real pulses counted are more than expected. Could be some
noise in the Encoder signals.
Note: for encoder with more than 8192 ppr the data showed in P79 loses of meaning
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.
2.1.4.4 RESOLVER
2.1.4.4.1 SENSOR PARAMETERS
It’s necessary have to set correctly the parameter
P68
Note: resolve poles number cannot be grater than motor poles number (P67),
otherwise it is
triggered the alarm A15 with code 0.
2.1.4.4.2 SPEED SENSOR TEST
It is in two parts:
o
Check that the direction of rotation of the motor phases and the Resolver
correspond;
o
Check that the number of motor poles is written correctly in parameter
P67
and the
Resolver used is correctly define as poles number with parameter
P68
Correct operation requires a no-load motor so decouple it from the load.
