p0300[0...n] Motor type selection / Mot type sel
Access level: 2
Can be changed: C(1, 3)
Units group: -
Min
0
Description: Selecting the motor type.
The first digit of the parameter value always defines the general motor type and corresponds to the third-party
motor belonging to a motor list:
1 = Rotating induction motor
2 = Rotating synchronous motor
The type information must be entered to filter motor-specific parameters and to optimize the operating characteris-
tics and behavior. For example, for synchronous motors, power factor (p0308) is neither used nor displayed (in the
BOP/IOP).
Value: 0:

Dependency: When selecting a motor type from the 1LA7 series, parameters p0335, p0626, p0627, and p0628 of the thermal
motor model are pre-assigned as a function of p0307 and p0311.
Note: Once the Control Unit has been powered up for the first time or if the factory settings have been defined accord-
ingly, the motor type is pre-configured to induction motor (p0300 = 1).
If a motor type has not been selected (p0300 = 0), then the drive commissioning routine cannot be exited.
p0301[0...n] Motor code number selection / Mot code No. sel
Access level: 2
Can be changed: C(1, 3)
Units group: -
Min
0
Description: The parameter is used to select a motor from a motor parameter list.
When changing the code number (with the exception to the value 0), all of the motor parameters are pre-assigned
from the internally available parameter lists.
Dependency: Code numbers can only be selected for motor types that correspond to the motor type selected in p0300.
Refer to: p0300
Note: The motor code number can only be changed if the matching catalog motor was first selected in p0300.
When selecting a catalog motor (p0300 >= 100), drive commissioning can only be exited if a code number is
selected.
p0304[0...n] Rated motor voltage / Mot U_rated
Access level: 1
Can be changed: C(1, 3)
Units group: -
Min
0 [Vrms]
Description: Sets the rated motor voltage (rating plate).
Caution: When selecting a catalog motor (p0301), this parameter is automatically pre-assigned and is write protected. Infor-
mation in p0300 should be carefully observed when removing write protection.
Note: When the parameter value is entered the connection type of the motor (star-delta) must be taken into account.
Once the Control Unit has booted for the first time or if the factory settings have been restored, the parameter is
pre-assigned to match the power unit.
