Programmable SyncPos motion controller
48 O_BRAKE
O_BRAKE indicates the output with which the brake
can be activated.
NEW: If an output is defined for the brake, this
remains active even when the program is termina-
ted with ESC.
O_BRAKE is activated in the case of an an abort or
option error if ERRCOND (43) is set to 1 or 3.
A positive number means that the output is high
(24 V) when the function is active. A negative num-
ber means that the output is low (0 V) when the
function is active.
NB!
The brake output must always be reset by an
OUT command in the program.

49 SYNCFACTM
The synchronization is described with a ratio of qc
(Master : Slave); SYNCFACTM determines the syn-
chronization factor for the master.
SYNCFACTM (49) and SYNCFACTS (50) make the
compensation of different drive factors possible or
the adaptation of the slave speed in relation to the
master speed set.
In conjunction with curve synchronization the para-
meters SYNCFACTM and SYNCFACTS are used to
transform qc into MU units. This allows the user to
work with meaningful units in the CAM-Editor. See
example 2 below.
provided that:
Encoder = Incremental encoder (the multi-
plier 4 is omitted in the case of
absolute encoders)
Scaling factor = Number of user units UU (qc)
that correspond to one revolution
at the drive.

Value range
1 … MLONG ★ 1
–MLONG … –1 = turns the direction of synchroni-
zation (ratio to the master)
Example 1
If the master is to run twice as fast as the slave, then
the ratio is 2 : 1
SYNCFACTM = 2
SYNCFACTS = 1
