Setting other important parameters

Other important parameters are stored in CoE object 8012hex.

Setting other important parameters 1:

8012:05 "Speed range"

When changing "Speed range": adjust "Reference velocity"

Recalculate the parameter "Reference velocity" if you have changed the parameter "Speed range".

The "Speed range" parameter has several functions:

  • Upper limit of the output step frequency.
  • Reference value for speed setpoints:
    Speed setpoints are given in % of the "Speed range".

Unit: Full steps per second
Factory setting: "2000 Fullsteps/sec"

The following formula can be used to determine the maximum achievable speed for a "Speed range":

 

Setting other important parameters 2:

nmax: Maximum achievable speed [rpm]

fmax: "Speed range" [full steps/s]

φ: Step angle of the motor [°]

8012:08 "Feedback type"

When changing the "Feedback type": adjust the "Scaling factor"

Recalculate the parameter Scaling factor if you have changed the "Feedback type" parameter.

Factory setting: "Internal counter"

  • If you are using an encoder, set this parameter to "Encoder". Parameterize the encoder.
  • Otherwise set this parameter to "Internal counter".
