Determine choke by means of

calculation, if necessary. It is

recommended to contact Rexroth!

Requirements on the choke:

-I

n_Dr

≥ I

n_Mot

The rated current of the choke has to be greater than or equal to the rated motor

current.

Ausgang, max.

;

PWM

Depending on the maximum speed, the choke is loaded with the respective

output frequency and the PWM frequency of the controller.

- Insulation class

The insulation class has to correspond at least to that of the motor or has to be

dimensioned for higher temperatures.

- The voltage load of the choke depends on the controller used.

Temperature Evaluation

Only such motors with incorporated temperature sensor should be

operated together with IndraDrive controllers, because only then can the

motor be thermally monitored by the controller and protected against

destruction by too high temperature rise.

The controller is informed on the temperature sensor type via parameter

P-0-0512, Temperature sensor. Standard sensor types are

characterized by a characteristic number. A characteristic stored in the

firmware is assigned to this number.

See "Motor Temperature Monitoring" in section "General Information on

the Operation of Motors with IndraDrive"

See Parameter Description "P-0-0512, Temperature sensor"
