4-212
Number of poles (17-06)
Set the motor pole number with its range is 2~16 poles. (even)
Motor no-load voltage (17-08)
(1)
Motor no-load voltage is mainly used in SLV mode, set to value 10~50V lower than the input
voltage to ensure good torque performance at the motor rated frequency.
(2)
When 17-08 set to 85~95% of the motor rated voltage. In general, the no-load voltage can be
closer to the motor rated voltage for larger motors, but cannot exceed the motor rated voltage.
(3)
The motor no-load voltage can be set to a value greater than the actual input voltage. In this
case, the motor can only operates under relatively low frequency. If the motor operates at the
rated frequency an over voltage condition may occur.
(4)
The higher the motor power is, the higher the no-load voltage is.
(5)
A smaller no-load voltage will reduce the no-load current. When load is applied the magnetic
flux is weakened and the motor current increases.
(6)
A higher no-load voltage results in a higher the no-load current. When load is applied the
magnetic flux weakens and the motor current increases. Increasing the magnetic flux generates
back EMF and results in poor torque control.
Motor excitation current (17-09)
(1)
Only the static-type or stator resistance measurement auto-tune (17-00=1 or 2) can be set.
(2)
Motor excitation current is used for rotational auto-tune.
(3)
Set motor excitation current to 33% of the motor rated current. During auto-tune the keypad
will display
“
Atune
“
for Auto-tune in progress. When the motor is successfully tuned, the
keypad shows "AtEnd".
Error history of automatic tuning (17-11)
(1)
If auto-tuning fails the keypad will display the AtErr" message and the auto-tune cause is shown
in parameter 17-11.
(2)
Refer to section 5 for troubleshooting and possible automatic tuning error causes.
Note：
The motor tuning error history (17-11) shows the tuning result of the last auto-tune. No error is
displayed when auto-tune is aborted or when the last auto-tune was successful.
Proportion of Motor Leakage Inductance (17-12)
(1)
Only the stator resistance auto tune (17-00=2) can be set.
(2)
The static non-rotational type and rotational type auto tune will automatically measure the
proportion of motor leakage inductance so this parameter is not active.
(3)
It is set the value to 4%. Refer to parameter 02-33 for test run to adjust.
Motor Slip Frequency (17-13)
(1)
Only the stator resistance auto tune (17-00=2) can be set.
(2)
The static non-rotational type and rotational type auto tune will automatically measure the
proportion of motor leakage inductance so this parameter is not active.
(3)
Refer to parameter 02-34 for counting the setting value.
