Commissioning

Fig. 118: Automatic linking of all main variables

• Several parameters have to be set before the motor can be started up. The values can be found in

sections "CoE settings [

}

109]" and "NC settings [

}

112]".

Please set these parameters before continuing with the motor commissioning procedure.

Configuring the main parameters - Settings in the CoE register

The specified data apply to an AS 1050-0120 stepper motor and are intended as an example. For other
motors the values may vary, depending on the application.

Adaptation of current and voltage

Attention

The motor may overheat!

In order to prevent overheating of the connected motor it is important to adapt the current
and voltage output from the stepper interface to the motor.

To this end set the index 8010:01 [

}

180] "Maximum current" and 8010:03 [

}

180] "Nominal voltage" in the

CoE register to suitable values (see Fig. "Adaptation of current and voltage").

Reduced current can be set in index 8010:02 [

}

180]. This reduces the coil current when at a standstill (and

therefore the power dissipation). Please note that the torque is also reduced.
