Setting important motor parameters

Note

Some motor parameters are not fault-tolerant

Incorrect motor parameters can result in damage.

Take care when setting the motor parameters.

The motor parameters are stored in CoE object 8010_hex.

To ensure safe commissioning, it is sufficient to set the following parameters correctly. Further motor parameters are described under CoE object 8010_hex: STM Motor Settings Ch.1.

8010:01 "Maximal current"

The maximum current that the current controller outputs per motor winding.

Unit: mA
Factory setting: 1500_dec(EPP7041-1002) / 5000_dec(EPP7041-3002)

The maximum value that should be entered here is the nominal motor current. The nominal current can usually be found in the data sheet of the motor.

8010:02 "Reduced current"

Winding current at motor standstill.

Unit: mA
Factory setting: 500_dec(EPP7041-1002) / 2500_dec(EPP7041-3002)

Criteria for setting this parameter:

A lower value results in a lower power loss when the motor is at standstill.
A higher value leads to a higher breakdown torque when the motor is at standstill.

8010:03 "Nominal voltage"

The DC link voltage you connect to X02.

	Risk of confusion: DC link voltage and nominal motor voltage Do not enter the nominal motor voltage here.

Unit: 1 mV
Factory setting: 50000_dec
