Table 6-40 Description of the phases for speed or position synchronism
Phases speed–synchronous
(P0410 = 1 or 3)
Initializing After the coupling has been switched–in, the speed setpoint for the slave drive is
ramped up to the master drive speed.
The ramp gradient corresponds to the acceleration in P0103.
This phase is completed after the slave drive has reached the speed of the master
drive.
Offset phase –
Synchronous For coupling–in/out using the input signal, the following applies (P0410 = 1, 2 or 7):
phase
––> A traversing program can be started.
For coupling–in/out using the traversing block, the following applies (P0410 = 3, 4 or
8):
––> The traversing program is continued.
Note:
S
The setpoint input via the angular incremental encoder interface, switched as input,
and the setpoint input via the traversing blocks are superimposed on one another.
S
Traversing blocks with relative position data are permissible.
S
––> refer under the index entry "Output signal, digital – in synchronism"
Braking phase After the coupling has been switched–out, the drive goes into the braking phase and
brakes down to standstill with the deceleration set in P0104.
For coupling–in/out using the input signal, the following applies (P0410 = 1, 2 or 7):
––> A traversing program can be started.
For coupling–in/out using the traversing block, the following applies (P0410 = 3, 4 or
8):
––> The traversing program is continued.
Note:
For coupling–in/out via input signal, the braking phase may only be initiated, if a tra-
versing program is no longer running for the slave drive.

position–synchronous
(P0410 = 2 or 4)
After speed synchronism
has been reached, the
summed following error

tered in P0412 is moved

P0413.
Absolute position
(P0410 = 2 or 4)
(from SW 4.1)
After speed synchronism
has been reached, the
drive moves by the offset in
the absolute position of the
master and slave drive and
the position offset, entered
into P0412 with speed v

+ P0413.
