10.5. CURRENT LOOP AUTO-TUNING COMMAND
This auto-tuning calculates the value L*In of the connected motor and saves it on parameter P58 so as to
optimise the response of the torque loop. To do this correctly, before starting the auto-tuning set at least the
following parameters:
P52 : maximum motor speed (r.p.m.)
P53 : number of motor poles
P54 : number of resolver poles
P56 : rated motor current in % of drive rated current
The motor must be free to rotate because during auto-tuning it makes a full polar rotation.
To start the auto-tuning you must:
1) be in STOP
2) set access key
P50 = 95 (see P99)
3) enter c45 programming, write "1" and press S
Once started the system reads the inductance for the first time, injecting a current equal to In into the motor
and then moves 30 electrical degrees 11 times, performing the measurement for each position. At the end
the system calculates the average value of the readings and then saves the value L*In calculated in
parameter
P58 and stops (the auto-tuning lasts about 15 seconds)
Before switching off the mains, remember to store the parameters on the permanent memory c43=1
10.6. RESOLVER PHASE AUTO-TUNING COMMAND
This auto-tuning calculates the phase displacement between the resolver and the motor so as to have the
maximum possible torque and saves this on parameter
P55 .
To do this correctly, before starting the auto-tuning set at least the following parameters:
P52 : maximum motor speed (r.p.m.)
P53 : number of motor poles
P54 : number of resolver poles
P56
: rated motor current in % of drive rated current
The motor must be free to rotate because during auto-tuning it makes a full polar rotation.
To start the auto-tuning you must:
1) be in STOP
2) set access key
P50
3) enter c44 programming, write "1" and press S
Once auto-tuning has started, the system performs the following operations in succession:
1) checks that the ratio between motor poles and resolver poles is correct
2) checks that the direction of rotation of the motor and the resolver is consistent
3) it moves in steps of 120 electrical degrees until one full rotation is completed. It then calculates the
value to be set in
P55 and saves it.
If during the auto-tuning the system stops in an alarm state, read the type of alarm, take the necessary
action, reset and start the auto-tuning again. In particular if:
1) A13 (wrong pole setting) triggers, verify which of the P53 (motor poles) or P54 (resolver poles)
parameters is not set correctly and correct it.
