Fig. 198: Signal diagram for PO pulse output with specified number of pulses for I1 - possible normal
mode phases
EN: Function block input for enable signal
S: Function block input for starting the pulse sequence
FO: Operating frequency,
FS: Start frequency,
QF: Current output frequency
m1 = Acceleration phase, m2 = Operating phase, m3 = Braking phase
AC: Positioning job active
BR: Function block input for stopping the pulse sequence
Q1/2: Pulse sequence at the device output Q1 and/or Q2
• Range A: The pulse sequence is present at the device output until the number of pulses defined at I1
has been reached.
• Range B: Activating the function block input BR initiates the braking phase and reduces the frequency
of the pulse sequence.
• Range C: Turning off function block input EN causes the device output to immediately turn off the pulse
sequence.
