d0-08
Mutual inductive reactance (asynchronous motor)
Default
Model dependent
Setting Range
0.1mH~6553.5 mH (Frequency inverter power
≤ 55 kW)
0.01mH~655.35 mH (Frequency inverter power
≥75 kW)
d0-09
No-load current (asynchronous motor)
Default
Model dependent
Setting Range
0.01A ~ d0-02 (Frequency inverter power
≤55 kW)
0.1A to d0-02 (Frequency inverter power
≥75 kW)
The parameters in d0-05 ~ d0-09 are asynchronous motor parameters. These parameters are unavailable on the
motor nameplate and are obtained by means of motor auto-tuning. Only d0-05 ~ d0-07 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 d0-05 ~ d0-09.
When the "Rated motor power" (d0-00) or "Rated motor voltage" (d0-01) is changed; the frequency inverter
automatically restores values of d0-05 ~ d0-09, to restore setting of these 5 parameters according to common
standard Y series asynchronous motor.
If it is impossible to perform motor auto-tuning onsite, manually set the values of these parameters according to
data provided by the motor manufacturer.
d0-15
Stator resistance (synchronous motor)
Default
Model dependent
Setting Range
0.001
Ω ~65.535 Ω (frequency inverter power≤ 55 kW)
0.0001
Ω ~ 6.5535 Ω (frequency inverter power
≥75 kW)
d0-16
Shaft D inductance (synchronous motor)
Default
Model dependent
Setting Range
0.01 mH ~655.35 mH (frequency inverter power
≤ 55 kW)
0.001~65.535 mH (Frequency inverter power
≥75 kW)
d0-17
Shaft Q inductance (synchronous motor)
Default
Model dependent
Setting Range
0.01 mH ~655.35 mH (frequency inverter power
≤ 55 kW)
0.001 mH~65.535 mH (frequency inverter power
≥75 kW)
d0-18
Back EMF (synchronous motor)
Default
Model dependent
Setting Range
0.1V~6553.5 V
The d0-15~d0-18 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" (d0-00) or "Rated motor voltage" (d0-01) is changed; the frequency inverter will
automatically modify the values of d0-15~ d0-18.
You can also directly set the parameters based on the data provided by the synchronous motor manufacturer.
d0-21
Encoder wires
Default

UVW wire-saving encoder
The EM12 supports multiple types of encoder. Different PG cards are required for different types of encoder.
Select the appropriate PG card for the encoder used. Any of the five encoder types is applicable to synchronous
