Configuration of Velocity Scaling
Velocity scaling is the relationship between the number of motor revolutions per minute and the required user-defined units (usr_v).
Velocity scaling is specified by means of scaling factor:
In the case of a rotary motor, the scaling factor is calculated as shown below:
The following factory settings are used:
o1 motor revolution per minute corresponds to 1 user-defined unit

Velocity scaling: Numerator. Specification of the scaling factor:
Speed of rotation of motor [RPM] -------------------------------------------------- User-defined units [usr_v]
A new scaling is activated when the numerator value is supplied. Type: Signed decimal - 4 bytes Write access via Sercos: CP2, CP3, CP4 Setting can only be modified if power stage is disabled. Modified settings become effective immediately. |
