03.38 : Encoder type
Adjustment range: Incremental (0), Reserved (1),
U,V,W only (2), Incremental UVW (3),
Hall effect sensor (4),
Software 1 / voltage oriented (5),
Software 2 /voltage oriented (6),
Software 3 /adaptive model (7),
Software 4 /flux oriented (8),
Software 5 /Reserved (9), Resolver (10).
Factory setting: Software 2 /voltage oriented (6).
CAUTION :
03.38 is only active for «Induction motor in vector control
mode» (11.31=2), «PM motor (Servo) in vector control
mode» (11.31=3), «Active rectifier for synchronous motor
(11.31=5) modes.
The drive must be equipped:
- With an MDX-ENCODER option for managing encoders
( 03.38 = 0 to 3) and managing Hall effect sensors ( 03.38 = 4).
- With an MDX-RESOLVER option for managing resolvers
( 03.38 =10).
If 11.31 = «Induction motor in vector control mode»
Incremental (0):
Speed feedback via quadrature incremental encoder with
A,A\,B,B\ signals. Related parameters:
03.34
and
03.42
Reserved (1):
N ot applicable
U,V,W only (2):
N ot applicable
Incremental U,V,W (3):
Same as «Incremental (0)».The U, V, W signals are not used.
Hall effect sensor (4):
Not applicable
Software 1 /voltage oriented (5):
«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 (6):
«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 (7, 8, 9):
Not applicable
Resolver (10):
Speed feedback via resolver
NB
:
Wh en 03.38 is set to one of the «software encoder» modes,
enter the menu 5 parameters (
05.06
to
05.10
) using the motor
nameplate data.
If 11.31 = «PM motor (Servo) in vector control mode »
Incremental (0):
Not applicable
Reserved (1):
Not applicable
U,V,W only (2):
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 (3):
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 (4):
Dedicated to permanent magnet machines fitted with 3 Hall
effect sensors phase-shifted by 120° electrical.
Software 1 /voltage oriented (5):
«Sensorless» mode in which the rotor position is determined
by reconstituting the motor Electro-Motive Force vector.
This mode is not suitable for machines with high cogging
(see 05.37 ). During the starting phase the motor is parked in
accordance with the description in the «Current vector» mode
in parameter 05.36 .
The parking phase is especially helpful for starting large fans
or crushers
Software 2 /voltage oriented (6):
«Sensorless» mode in which the rotor position is determined
by reconstituting the motor Electro-Motive Force vector. This
mode is not suitable for machines with high cogging (see
05.37 ) and applications where the ratio between the load
inertia and the motor inertia is more than 80.
Software 3 /adaptive model (7):
«Sensorless» mode in which the rotor position is determined
from an adaptive model of the machine in which the voltage
and current values linked to a rotational reference point are
compared with the actual measurements.
Starting phase: see parameter 05.36 .
Software 4 /flux oriented (8):
«Sensorless»
mode in which the rotor position is determined
by reconstituting the machine flux in a fixed reference point.
Starting phase: see parameter 05.36 .
This mode is recommended for applications where the ratio
between the load inertia and the motor inertia is more than 80.
Software 5 (9):
Not applicable.
Resolver (10):
Dedicated to machines fitted with a resolver.
NB
:
When 03.38 is set to one of the «Software 1 to 5» modes, fill
in parameters
05.06
to
05.10 and 05.24
,
05.33
,
05.51
using
the motor nameplate data, then perform an autotune
«Stationary: motor data completed» (
05.12
= 1)
.
When the nameplate data is not available, perform an autotune
procedure «Rotating: motor data incomplete» (
05.12
= 2).
If the drive unjustifiably trips due to «Overcurrent» when the
motor is hot or at full load, the values of 05.24 and 05.33 can
be adjusted as below:
05.24 = 90% of the specified inductance value.
05.33
= 95% of the specified EMF value to take account of the
decrease in flux related to the temperature.
