Fig. F2-1 parameters R1, X11, R2, X21, Xm, I0
represent stator resistance, stator leakage
inductive reactance, mutual inductive
resistance, no-load current.
If there is tuning for the motor, the set
value of F2.06 ～ F2.10 will be updated after
tuning. After modifying the rated power
F2.01 of asynchronous motor, F2.03 ～ F2.10
parameters will be updated with default
parameters of asynchronous motor with
corresponding power (F2.02 is rated frequency
of motor, not included in the default
parameter range of asynchronous motor, and
need to be set according to nameplate).

Notice:
◇
when set F2.16 as 2, if over current or tuning fault
occurs during tuning, check if there is phase loss
and whether the machine type matches;
◇
when set F2.16 as 2, free motor shaft from load
during complete tuning to prevent motor from
complete tuning with load;
◇
insure the motor staying at stopped state before
activating motor parameter tuning, or it won't
process normally;
◇
in some condition (like that motor can't be
detached from load) that complete tuning can't be
conducted conveniently or no high requirement
is asked for the motor control performance, static
tuning can be used;
◇
if tuning can't be conducted, users can input
motor nameplate parameters (F2.01 ～ F2.14)
if they are acquired precisely, and the VFD can
still demonstrate a high performance. If tuning
fails, protection action will be activated and E-21
displayed.
4.2 Detailed Function Description
Parameter measurement mode when motor
stays in static state. This mode is suitable for
condition where motor can't be apart from
load.
2: complete tuning
A complete parameters measurement of
motor. Choose this mode for best when
motor can be apart from load.
