The contacts of the function block are connected with markers.
Parametric programming of the function block inputs/outputs
When using the function block in the circuit diagram for the first time, use
OK to automatically enter the general display of function block parameters,
as shown in the figure. Enter the function block settings here.
Function of the function block
The function block is active if the PO..EN coil is actuated. After you have
parameterized the function block, you can actuate the coil PO..S_. This will
start normal operation. Alternatively, you can also actuate the coil PO..TP and
start the function block in Jog mode.
If the voltage at the coil PO..EN drops out, the pulse sequence at the output
is immediately switched off and the function block is reset.
→
Bear in mind that a motor with sufficient inertia may not come to a
standstill immediately after the pulse sequence is switched off.
The function block sends 24 V pulse sequences at output Q01 (function
block PO01) or Q02 (function block PO02). The frequency of the pulse
sequence is determined by the parameters that are described in the sections
Normal mode and Jog mode.
Procedure with possible faults for normal and jog mode
•
If the function block detects parameter errors directly at the start, no
pulse sequences are output to the device output.
•
If the function block detects a faulty parameter change during a pulse
sequence, the pulse sequence is reduced in accordance with the brake
ramp.
