F1-09
Mutual inductive
reactance
(asynchronous motor)
0.1–6553.5 mH (AC drive power ≤ 55 kW)
0.01–-655.35 mH (AC drive power > 55 kW)
Model
dependent
F1-10
No-load current
(asynchronous motor)
0.01 to F1-03 (AC drive power ≤ 55 kW)
0.1 to F1-03 (AC drive power > 55 kW)
Model
dependent
The parameters in F1-06 to F-10 are asynchronous motor parameters. These parameters
are unavailable on the motor nameplate and are obtained by means of motor auto-tuning.
Only F1-06 to F1-08 can be obtained through static motor auto-tuning. Through complete
motor auto-tuning, encoder phase sequence and current loop PI can be obtained besides
the parameters in F1-06 to F1-10.
Each time "Rated motor power" (F1-01) or "Rated motor voltage" (F1-02) is changed, the
AC drive automatically restores values of F1-06 to F1-10 to the parameter setting for the
common standard Y series asynchronous motor.
If it is impossible to perform motor auto-tuning onsite, manually input the values of these
parameters according to data provided by the motor manufacturer.

0.01–655.35 mH (AC drive power ≤ 55 kW)
0.001–65.535 mH (AC drive power > 55 kW)
Model

F1-18
Shaft Q inductance
(synchronous motor)
0.01–655.35 mH (AC drive power ≤ 55 kW)
0.001–65.535 mH (AC drive power > 55 kW)
Model

F1-20
Back EMF
(synchronous motor)
0.1–6553.5 V
Model
dependent
F1-16 to F-20 are synchronous motor parameters. These parameters are unavailable on the
nameplate of most synchronous motors and can be obtained by means of "Synchronous
motor no-load auto-tuning". Through "Synchronous motor with-load auto-tuning", only the
encoder phase sequence and installation angle can be obtained.
Each time "Rated motor power" (F1-01) or "Rated motor voltage" (F1-02) is changed, the
AC drive automatically modies the values of F1-16 to F1-20.
You can also directly set the parameters based on the data provided by the synchronous
motor manufacturer.
Function Code Parameter Name Setting Range Default
F1-27 Encoder pulses per revolution 1–65535 1024
This parameter is used to set the pulses per revolution (PPR) of ABZ or UVW incremental
encoder. In CLVC mode, the motor cannot run properly if this parameter is set incorrectly.
