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

+ ... Advantageous combination
o ... Combination is possible, commissioning may be more complicated!

Note: For information on absolute and relative measuring systems
see section "Measuring Systems"!
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!
