Code Description
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
volta
ge, 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.
