2.4.47.5 Acceleration functions
Under C0104, you can select the following acceleration functions for the linear ramp function
generator:
Code Function Application
C0104 = 0 The drive starts and stops with constant acceleration.
The actual acceleration time is proportional to the selected
setpoint and the activated T
i
time. The following formula
applies:

C0104 = 1 The drive starts and stops in the activated T
i
time.
The selected setpoint has no influence on the acceleration
time. The following formula applies:
With acceleration with a fixed time, a drive system is, for
instance, simultaneously accelerated and decelerated to
standstill. The individual drives can have different speed values.

C0104 = 2 The drive starts and stops with a predefined number of
revolutions or over a selected distance.
The actual acceleration time results from the selected setpoint
and the activated T
i
time. The following formula applies:
With acceleration over a specified distance, the distance
selected via the T
i
time is traversed when the drive is
decelerated to standstill. The speed does not have any
influence.

Start and stop with a preselected time or distance is only possible with the control signal at
NSET−RFG−0 and after controller enable.
