Mtr.09 : Motor volt per 1000 rpm (Ke) ( )
This is the value of the motor voltage for 1000 rpm.
The value of Mtr.09 is used in permanent magnet motor
sensorless control mode ( Mtr.10 = Software encoder n°1 or
Software encoder n°2).
This electromotive force should be entered from the nameplate
by setting the Ke value on the nameplate, or else using the
autotune procedure (see Ctr.14 ).
Note:
This parameter is only visible if Ctr.02 = PM motor (Servo) in
vector control mode.
Mtr.10 : Encoder type
• If Ctr.02 = Induction motor in vector control mode:
Incremental: speed feedback via quadrature incremental
encoder with A,A\,B,B\ signals
Reserved:
Not applicable
U,V,W only:
Not applicable
Incremental U,V,W:
Speed feedback via quadrature incremental encoder with
A,A\,B,B\ signals . The U,V,W signals are not used.
Hall effect sensor:
Not applicable
Software 1 /voltage oriented:
«Sensorless» mode in which the position is reconstituted
by the software. Recommended for applications where low
starting torque is required (pump, fan, etc).
Software 2 /voltage oriented (#):
«Sensorless» mode in which the position is reconstituted
by the software. Recommended for applications where high
starting torque is required (grinder, press, extruding machine,
etc).
Software 3 to 5:
Not applicable
Resolver:
Speed feedback via resolver, dedicated to machines fitted
with a resolver.
• If Ctr.02 = PM motor (Servo) in vector control mode:
Incremental:
Not applicable
Reserved:
Not applicable
U,V,W only:
This selection allows use in downgraded operation of an
encoder with commutation signals whose A and B channels
are not operational.
Incremental U,V,W:
Dedicated to permanent magnet machines fitted with an
incremental encoder with A,A\,B,B\ signals and U,U\ V,V\
W,W\ commutation channels.
Hall effect sensor:
Dedicated to permanent magnet machines fitted with 3 Hall
effect sensors phase-shifted by 120° electrical.
Software 1 /voltage oriented:
«Sensorless» mode reserved for «Advanced» mode.
Software 2 /voltage oriented (#):
«Sensorless»
mode in which the rotor position is determined
by reconstituting the motor Electro-Motive Force vector. This
mode is not suitable for applications where the ratio between
the load inertia and the motor inertia is more than 80.
Software 3 /adaptive model:
«Sensorless» mode reserved for the «Advanced» menu.
Software 4 /flux oriented:
«Sensorless»
mode reserved for the «Advanced» menu.
Software 5:
Not applicable
Resolver:
Speed feedback via resolver, dedicated to machines fitted
with a resolver.
NB:
When Mtr.10 is set to «Software 2/voltage oriented» , fill in
parameters
Mtr.01
to
Mtr.04
and
Mtr.08
,
Mtr.09
using the
motor nameplate data, then perform an autotune Ctr.14 =
«Stationary: motor data completed»
.
When the nameplate
data is not available, perform an autotune procedure Ctr.14 =
«Rotating: motor data incomplete».
If the drive unjustifiably trips due to «Overcurrent» when the
motor is hot or at full load, the values of Mtr.08 and Mtr.09 can
be adjusted as below:
Mtr.08
= 90% of the specified inductance value.
Mtr.09 = 95% of the specified EMF value to take into account
the decrease in flux related to the temperature.
Mtr.11 : Encoder lines per revolution
Used to configure the number of lines per incremental encoder
revolution. Converts the encoder input into a speed.
Mtr.12 : Encoder supply voltage
5V (#):
This parameter is used to set the encoder supply voltage to 5V.
15V:
This parameter is used to set the encoder supply voltage to 15V.
CAUTION:
Before selecting «15V», check that the encoder used can
withstand this voltage.
Mtr.13 : Position feedback phase angle ( )
Indicates the result of the phasing test performed
during autotuning (see Ctr.14 ). It is stored when the drive is
powered down and will only be modified automatically after
another autotune.
• The phase angle, when it is known, can be
entered manually. Any incorrect value can cause
the motor to rotate in the wrong direction or trip the drive.
