Code Description
Note that the rotor time constant (Tr) must be
measured in a stopped position.
2 All (static
type) Measures all parameters while the motor is in
the stopped position, including stator resistance
(Rs), no-load current (Noload Curr), rotor time
constant (Tr), etc. Since the motor is not rotating
while the parameters are measured, the
measurements are not affected when the load is
connected to the motor spindle. However, when
measuring parameters, do not rotate the motor
spindle on the load side.
BAS-14 Noload Curr,
BAS-21 Rs–BAS-24 Tr
Displays motor parameters measured by auto tuning. For parameters
that are not included in the auto tuning measurement list, the default
setting will be displayed.
•
Perform auto tuning ONLY after the motor has completely stopped running.
•
Auto tuning operates when the inverter’s auto mode is off.
•
Before you run auto tuning, check the motor pole number, rated slip, rated current, rated voltage,
and efficiency on the motor’s rating plate and enter the data. The default parameter setting is
used for values that are not entered.
•
When measuring all parameters after selecting 2 ( All-static type) at BAS-20: compared with
rotation type auto tuning where parameters are measured while the motor is rotating, parameter
values measured with static auto tuning may be less accurate. Inaccuracy of the measured
parameters may degrade the performance of operations. Therefore, run static-type auto tuning
by selecting 2 (All) only when the motor cannot be rotated (when gearing and belts cannot be
separated easily, or when the motor cannot be separated mechanically from the load).
•
If auto tuning operates without wiring the motor, ‘Rs Tune Err’ or ‘Lsig Tune Err’ warning messages
are displayed. It can be reset if you press ‘STOP/RESET’ button of the keypad.
