If motor's parameters are available, please set
FH.04 ~FH.07 to the values calculated according
to the above formula.
If the drive performs auto-tuning of motor's
parameters, then the settings of FH.03~FH.07
after the auto-tuning process will be updated.
After motor power(setting of FH.01) is changed,
the drive will set FH.02~FH.07 to corresponding
parameters.
FH.08 Rated slip
frequency
Motor's rated slip frequency can be calculated by
the motor's rated speed (on the nameplate):
Rated slip frequency = motor's rated frequency
(i.e. basic operating frequency F0.06)×(motor's
synchronous speed-motor's rated speed)÷
motor's synchronous speed.
Where: motor's synchronous speed = motor's
rated frequency ×120÷number of motor's
poles(FH.00)
After setting the slip frequency, the slip
compensation will be enabled by F3.07~F3.09.
FH.09 Auto tuning
FH09 can be used to measure and write-in the
motor's parameters automatically.
0: Auto-tuning is disabled
1: Stationary auto-tuning (Start auto-tuning to a
standstill motor)
Before starting auto-tuning, values on the motor's
nameplate must be input correctly (FH.00～
FH.02).
When starting auto-tuning to a standstill motor,
the stator's resistance (%R1), rotor's resistance
(%R2) and the leakage inductance (%X1) will be
measured and the measured values will be
written into FH.04, FH.05 and FH.06
automatically.

EV1000 Series General Purpose Variable Speed Drive User Manual
When starting a rotating auto-tuning, at first, the
motor is in standstill status, and the stator's
resistance (%R1), rotor's resistance (%R2) and
the leakage inductance (%X1) will be measured,
and then the motor begins to rotate, mutual
inductance (％XM), I
written into FH.04, FH.05, FH.06, FH.07 and
FH.03 automatically.
After auto-tuning, FH.09 will be set to 0
automatically.
Auto-tuning procedures:
1) Set the "F0.06 basic operating frequency" and
"F0.07 Max output voltage" correctly according to
the motor's feature;
2) Set the FH.00, FH.01 and FH.02 correctly;
3) If FH.09 is set to 2, Acc time (F0.10) and Dec
time (F0.11) should be set correctly and remove
the load from the motor and check the safety;
4) Set FH.09 to 1 or 2, press FUNC/DATA, and
then press RUN to start auto-tuning;
5) When the operating LED turns off, that means
the auto-tuning is over.
Note：
When setting FH.09 to 2, you may increase Acc/Dec
time if over-current or over-voltage fault occurs in the
auto-tuning process;
When setting FH.09 to 2, the motor's load must be
removed before starting rotating auto-tuning;
The motor must be in standstill status before starting
the auto-tuning, otherwise the auto-tuning cannot be
executed normally;
If it is inconvenient to start auto-tuning (e.g. the motor
cannot break away from the load), or you don't
require much on motor's control performance, you can
use stationary auto-tuning or even disable the function.
You may input the values on the motor's nameplate
correctly (FH.00~FH.02).
If the auto-tuning function is unavailable and there is
motor's parameters on the nameplate, you should
input the values correctly (FH.00~FH.02), and then
input the calculated values (FH.03~FH.07). Please set
the parameters correctly.
If auto-tuning is not successful, the drive alarms and
displays fault E024.
