3.12 Motor data identification
The stationary MotID can result in slight movement of up to 210 degrees electrical.
For the rotating motor data identification routine, motor motion is initiated, which can reach
the maximum speed (p1082) and the motor torque corresponding to the maximum current
(p0640).
The rotating measurement should be carried out with a motor running at no load (de-
coupled from the mechanical system) in order to prevent damage/destruction to the load or
be influenced by the load. If the motor cannot be de-coupled from the mechanical system,
then the stress on the mechanical system can be reduced by parameterizing the ramp-up
time (p1958) and/or using a speed limit (p1959.14/p1959.15) or using the current and
speed limit.
If a mechanical distance limit has been set, you are advised not to carry out the rotating
measurement.
The emergency OFF functions must be fully operational during commissioning.
To protect the machines and personnel, the relevant safety regulations must be observed.
