Object 6094
h
: velocity_encoder_factor
The velocity_encoder_factor object serves to convert all speed values of the application
from speed_units
to the internal unit of revolutions per minute.
The object consists of two parts: A factor for conversion of internal length units to
position_units and a factor for conversion of internal time units to user−defined time units.
The velocity_encoder_factor is calculated using the following formula:
velocity_encoder_factor + numerator
divisor
Object 6097
h
: acceleration_factor
The acceleration_factor object serves to convert all acceleration values of the application
from acceleration_units
to the internal unit of revolutions per minute per 256 seconds.
The object consists of two parts: A factor for conversion of internal length units to
position_units and a factor for conversion of internal time units to user−defined time units.
The acceleration_factor is calculated using the following formula:
acceleration_factor + numerator

Setting of the signs of
position and speed values.
By changing the sign, the
direction of rotation can be
inverted.
Often it makes sense to set
both flags to the same value.
