FUNCTION CODES
Chap 5
P30
PMSM drive Motor 1 (Magnetic pole position detection mode)
Related function codes:
P74:PMSM Motor 1 (Reference current at starting)
P87:PMSM Motor 1 (Reference current for polarity discrimination)
P30 specifies the magnetic pole position detection mode. Select the appropriate mode that matches the PMSM to
be used.
Data for P30 Function Remarks
0: Pull-in by current
No magnet pole position detection is made.
At the start of driving the motor, the inverter supplies current
specified by P74 to pull in the magnetic pole position.
In this position detection mode, the motor may rotate slightly in
the direction opposite to the commanded direction depending
upon the current motor shaft position.
—
1: For IPMSM (Interior
permanent magnet
synchronous motor)
The inverter starts the motor with the magnetic pole position
detection suitable for IPMSM.
The reference current for polarity discrimination specified by P87
applies. Usually it is not necessary to change the factory default.
—
2: For SPMSM (Surface
permanent magnet
synchronous motor)
The inverter starts the motor with the magnetic pole position
detection suitable for SPMSM. —
3: Pull-in by current for
IPMSM (Interior
permanent magnet
synchronous motor)
The inverter starts the motor with the magnetic pole position
detection suitable for IPMSM causing no magnetic saturation.
In this position detection mode, the motor may rotate slightly in
the direction opposite to the commanded direction depending
upon the current motor shaft position.
—
The reference current for polarity discrimination specified by P87 applies. Usually it is not necessary to
change the factory
default.
During the magnetic pole position pull-in operation or the magnetic pole position detection, the motor
cannot generate enough torque. When applying to the application which needs torque at start, engage
the mechanical brake by using brake signal
BRKS until magnetic pole position pull-in operation
is
comple
ted. ( Function code E20)
P53
Motor 1 (%X correction factor 1)
This is a factor for correcting the variation of leakage reactance %X. Basically, there is no need to modify the
setting.
P55
P56
Motor 1 (Torque current under vector control)
Motor 1 (Induced voltage factor under vector control)
P55 specifies the rated torque current; P56 specifies the induced voltage factor under vector control with speed
sensor.
The combination of P99 (Motor 1 selection) and P02 (Motor 1 rated capacity) data determines the standard value.
Basically, there is no need to modify the setting.
P60 to P64
PMSM Motor 1 (Armature resistance, d-axis inductance, q-axis inductance, Induced
voltage, and Iron loss )
P60 through P64 specify the armature resistance, d-axis inductance, q-axis inductance, induced voltage and iron
loss of the motor, respectively.
The combination of P99 (Motor 1 selection) and P02 (Motor 1 rated capacity) data determines the standard value.
Basically, there is no need to modify the setting.
