Determining the voltage constant of a motor experimentally

If the voltage constant k_e is not specified in the motor data sheet, you can determine it experimentally.

The voltage constant k_e is only required if you are not using an encoder but want to use one of the following functions:

• Load angle detection
• Step loss detection

The procedure is described in section "Induced countervoltage".
