12.1 General Information on Startup IndraDyn H Motors

The following points must be heeded especially when starting up

IndraDyn H frameless synchronous motors.

IndraDyn H motors are frameless motors whose individual components –

supplemented by an encoder system – are directly installed into the

machine by the manufacturer. As a result, frameless motors have no

data memory to supply motor parameters, standard controller settings,

etc. During startup, all parameters must be manually entered or loaded

into the drive. The startup program DriveTop provides all Bosch Rexroth

motor parameters.

If you view the A-side (opposite the cable outlet), the encoder must

indicate a positive command value if the rotor is turning clockwise. This

connection must be established before commutation adjustment.

For IndraDyn H motors, it is generally necessary to receive the position

of the rotor compared to the stator immediately after startup or after a

malfunction. This is called identification of pole position or commutation

adjustment. The commutation adjustment process is therefore the

establishment of a position reference to the electrical or magnetic model

of the motor. The commutation adjustment method depends on the

encoder type used.

In addition to the motor documents listed here, you need further
