6. Function blocks
6.1 Manufacturer function blocks
Number of steps at function block input P1
The number of steps that the motor should be able to execute in jog mode.
Frequency change per step in the acceleration phase RF
During the acceleration phase [1], the motor's step sequence frequency is increased
continuously from the start frequency to the operating frequency.
The frequency change per step is used to define the number of steps that the accel-
eration phase will take with the configured starting and operating frequencies.
Frequency change per step in the braking phase RF
During the deceleration phase [3], the motor's step sequence frequency is
decreased continuously from the operating frequency to the start frequency.
The frequency change per step is used to define the number of steps that the decel-
eration phase will take with the configured starting and operating frequencies.
Number of pulses (total number of pulses) I1
The total number of pulses needs to be configured based on the distance being
covered on the basis of the specified step angle per step.
In normal operation the func-
tion block will always move a
distance specified by the Total
number of pulses.
This value for the total number of pulses and the calculated number of pulses for the
acceleration and braking sequence are used by the function block to calculate the
number of pulses for the operating sequence [2].
Number of pulses for acceleration and braking
The PO function block automatically calculates the number of pulses required for
acceleration and braking using the frequency change values FS->FO and FO->FS you
have set.
You can calculate the number of pulses for the acceleration and braking sequence
using the following equations.

FO: Operating frequency [Hz]; FS: Start frequency [Hz],
n
RRF
: Number of pulses in the acceleration sequence
n
RBF
: Number of pulses in the braking sequence
RF: Frequency change in the acceleration phase [mHz/step]
BF: Frequency change in the braking phase [mHz/step]
