If one of the two device outputs Q01 or Q02 is used several times due to
a user error in the circuit diagram, the pulse sequence of the PO function
block is not output at the device output.
The function block can be used for normal operation and jog mode.
Normal operation
The following parameters are required for normal mode:
A rising edge at the PO..S_ coil starts normal operation.
A pulse sequence with the start frequency is initiated at the device output.
The frequency starts continuously up to the operating frequency, depending
on parameter RF. The function block determines the start of the braking
phase from the parameters I1, BF, FO and FS. From this point, the operating
frequency is continuously reduced down to the starting frequency as a
function of parameter BF.
After the function block is started properly, contact AC is closed until the
braking phase is completed. Contact E1 is closed if the function block
detects incorrect parameters at the start.
In order to stop Normal mode, actuate the BR coil. In this case, the pulse
frequency will be reduced according to the braking ramp.
A further rising edge at S has no effect if normal mode is activated.
