6. Function blocks
6.1 Manufacturer function blocks
load torque is taken into account, the start frequency must only be high enough for the
motor not to lose any pulses during acceleration and not to be driven by the load during
deceleration.
If the value of FS is set too low, this may cause oscillations
between the motor and the load. Jumps at the start or end of
the positioning section may occur if FS is set too high.
Operating frequency FO
The maximum operating frequency also depends on the load torque.
The motor generally achieves its maximum power and torque at very low speeds. The
higher the speed, the weaker the motor will be.
Jog frequency PF
The maximum frequency that the motor should be able to reach in jog mode.
Number of steps 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 function block will always move a dis-
tance 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 num-
ber 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 accel-
eration and braking using the frequency change values FS->FO and FO->FS you have
