0x6048 vl_velocity_acceleration
This object is used to configure the delta speed and delta time of the
slope of the acceleration ramp.
Example: To ramp to 1000 rpm in 5 s, possible values for delta speed
and delta time are 10000 and 50 respectively.
vl_velocity_acceleration = delta speed / delta time
Table 9-84 0x6048 vl_velocity_acceleration
9.20.7
0x6049 vl_velocity_deceleration
This object is used to configure the delta speed and delta time of the
slope of the deceleration ramp.
Example: To decelerate by 800 rpm in 10 s, possible values for delta
speed and delta time are 8000 and 100 respectively.
vl_velocity_deceleration = delta speed / delta time
Table 9-85 0x6049 vl_velocity_deceleration
9.20.8
0x604A vl_velocity_quick_stop
This object is used to configure the delta speed and delta time of the
slope of the deceleration ramp for quick stop.
Example: To decelerate by 800 rpm in 10 s, possible values for delta
speed and delta time are 8000 and 100 respectively.
vl velocity deceleration = delta speed / delta time

0x604B vl_setpoint_factor
This object is used to configure the numerator and denominator of the
vl_setpoint_factor
. The
vl_setpoint_factor
modifies the resolution or
directing range of the specified setpoint. It does not influence the velocity
limit function and the ramp function. A value of 0 must not be used.
Table 9-87 0x604B vl_setpoint_factor
9.20.10 0x604C vl_dimension_factor
This object is used to configure the numerator and denominator of the
vl_dimension_factor
. The
vl_dimension_factor
is used to scale the user
units so that they can be used in a way that relates to the specific
application.
Calculating the vl_dimension_factor:
Every user-specific velocity consists of a specific unit referred to as a
specific unit of time (e.g. 1/s, bottles/min, m/s,...). The purpose of the
vl_dimension_factor
is to convert this specific unit to the revolutions/
minute unit. A value of 0 must not be used.
Velocity [user-defined unit] / Dimension factor [rpm/user-defined
unit] = Velocity [rpm]
