2 ASYNCHRONOUS PARAMETERS
The "Asyncrhonous Parameters" are used to control the current or speed of a feedback vector
induction motor. The speed and current reference values are generated by the application. See the
application parameters for further information. As an absolute position value is not required for the
sensors (managed with an optional internal electronic board) incremental TTL Encoders and
incremental Sin/Cos Encoders may be used. Absolute sensors such as Resolver can also be used,
as can digital sensors such as Endat or Hiperface if required.
The "Asyncrhonous Parameters" also manages the auto-tuning test, which is crucial if the control is
to adapt perfectly to the motor and to ensure excellent dynamic performance all-round.
2.1 DRIVE AND MOTOR COUPLING
This section is usefull during motor start-up to obtain the best coupling between drive and
motor. It's very important to follow the correct sequence explained in the next paragraphs
2.1.1 DRIVE PLATE

P103 - Drive limit current
DRV_F_PWM
P101 - PWM frequency
P156 - PWM frequency
DRV_F_PWM_CARATT

P167 - Characterization
DRV_E_CARATT

value during overload
This parameters are related to the drive characteristic. The user has to set only the main supply
voltage and select the current overload.
