Asynchronous motors can also be controlled by IndraDrive controllers in
"open-loop" operation. This does not require any motor encoder! "Closed-
loop" operation does require a motor encoder, for asynchronous motors a
relative measuring system is sufficient.
For operationally reliable drives with synchronous third-party motors at
IndraDrive controllers the following possible combinations or restrictions
have to be taken into account when selecting the measuring system:
Drive range
Motor measuring

Synchronous third-
party motor
absolute

relative

Advantageous combination

Combination is possible, commissioning may be more complicated!

For information on absolute and relative measuring systems
see section "Measuring Systems"!
Determining the Motor Parameter Values
Before the commissioning procedure it is necessary to determine the
motor parameter values for the respective third-party motor. For this
purpose the motor manufacturer has to make available specific motor
data (see below "Required Manufacturer-Side Output Data for Third-Party
Motors").
The motor parameter values can be determined in different ways:
•
For motors that had already been used with Diax/EcoDrive, the
existing motor parameter values can be converted to IndraDrive.
•
For rotary asynchronous motors, the motor parameter values can be
determined controller-internally on the basis of the type plate data.
•
By means of the manufacturer-side, specific motor data the motor
parameters can be calculated via DriveTop or using formulas.
Note:
For project planning and commissioning of a third-party motor
the required, manufacturer-specific motor data must always be
available!
