to be carried out. The test of the drive system and compliance with the
directives have to be guaranteed by the machine manufacturer.
Third-Party Motors to be Controlled
The following motor types can be controlled:
• asynchronous motors, rotary
• asynchronous motors, linear
• synchronous motors, rotary
• synchronous motors, linear
These motors can be operated within the scope of the technical data of
the selected IndraDrive controller. If motors have been provided with a
holding brake, it should be controlled via the controller. Make sure that the
relevant technical data of the motor holding brake are complying with
those of the holding brake output.
Note: For third-party motors Bosch Rexroth, as a matter of principle,
does not assume the guarantee for the power data at the
motor shaft!
In the case of synchronous motors, the commutation offset has to be set
during commissioning. The drive firmware provides several methods for
determining this offset so that it is possible to determine the value for
different motor characteristics.
Note: Observe the restrictions in conjunction with the commutation
offset determination when using synchronous motors!
See Functional Description of firmware "Motor Control:
Commutation Setting" in chapter "Drive Control"
Possibly available reluctance property cannot be used for synchronous
third-party motors! For third-party motors it is impossible to determine fail-
safe motor parameter values for using the reluctance property; the
respective bit of P-0-4014, Type of construction of motor therefore
mustn't be set!
Requirements on Third-Party Motors
For successful and fail-safe use of a third-party motor check
• whether the third-party motor to be controlled satisfies the voltage
loads,
• which controller, including supply, is suitable due to the motor power to
be delivered,
• whether the third-party motor has the required minimum inductance,
• whether the motor can be protected against inadmissible temperature
rise in the case of overload (temperature evaluation),
• whether the mounted position measuring system can be evaluated by
the controller or which position measuring system can be selected for
kit motors.
Voltage Load of the Third-Party Motor
The voltage load of the insulation system of a motor occurring in practical
application is mainly influenced by the following characteristics:
• The output variables of the drive controller which is used (feed the
transmission distance).
