6.1 Manufacturer function blocks
The function block and its parameters
Function block inputs
Description Note
(Bit)
EN 1: Activates the function block. The checkbox for the
Function block release by EN is neces-
sary
parameter must first be enabled
EN Enable of the function block on status 1.
The operations Start positioning job (S_) or
Jog mode (TP) can be executed when the func-
tion block is enabled.
Disable the function block on status 0.
The function block Reset is carried out when
there is falling edge from 1 to 0. Caution! In normal operation always stop
a positioning job via the BR input.
In this case, the step sequence frequency
will be reduced according to the braking
ramp and the motor will brake gently.
A stop with EN= 0 would cause an abrupt
stop of the motor and a possible loss of the
reference point if this would be dragged
further by the moved load.
S_ The positioning job will start when there is a
rising edge.
An active positioning job will be signaled
with AC =1. When a positioning job is activated, the
acceleration, operating and braking
phases are executed in succession.
If a positioning job is already activated, a
renewed rising edge 0 -> 1 at S_ will not
cause a new job to be started.
BR Aborts the ongoing positioning job when there
is a rising edge. After the positioning job is aborted, the
function block now runs the braking
phase, i.e. a delayed motor stop is
executed.
The bit output AC is only set to 0 when the
braking phase has been completed.
TP Activates the Jog mode on status 1
The on duration TP = 1 determines the type of
Jog mode. Two operating mode are available in Jog
mode for diagnostics and testing.
1. Positioning with a preset number of
steps
TP on duration < 0.5 seconds
The motor moves by the number of steps
defined at P1.
2. Positioning with a specified jog fre-
quency - manual mode
TP on duration ≥ 0.5 seconds
The motor will be accelerated to the jog
frequency set at PF. The movement will be
continued until the jog command is
stopped with TP = 0.
(DWord)
I1 Number of pulses For number of pulses enter the total num-
ber pulses for the entire sequence, con-
sisting of the three individual acceleration,
operating and braking phases.
