24 V DC 24V power supply for switches etc.
24 V DC 24V power supply for switches etc.
Disable Resync The Resync function (to be enabled by param
1924) can be temporarily disabled by setting
this input to 1
Home run Starts the homing.
GND Ground for 24 V.
Reset/Enable Error reset on rising edge. To enable opera-
tion, this input must be switched to "1". "0" =
motor coast.
Test run reverse Test run; Program 1:
Test run reverse at the speed defined in Pa-
rameter 19-01
Speed/Pos - Synchronous operation; Program 2:
In velocity synchronous mode (P. 1901 = 0, 3,
6 or 7) the gear ratio and thus the velocity of
the slave can be changed by the value speci-
fied in parameter 1912.
In position synchronous and marker synchro-
nous operation (P. 1901 = 1, 2, 4 or 5), the
position offset of the slave can be changed by
the value specified in Parameter 1912. The
sign of the value in parameter 1912 selects the
offset type to be absolute or relative.
Absolute offset means that the fixed offset of
parameter 1912 is changed and this offset is
executed when restarting synchronisation.
Relative offset means that the actual slave po-
sition is displaced but the fixed offset of pa-
rameter 1912 is unchanged. This again means
that the actual slave position is maintained
when restarting synchronisation. Relative off-
set is useful when always changing the offset
in the same direction as this would give a very
high fixed offset when using absolute offset.
This high fixed offset would then be executed
when restarting synchronisation and the min.
or max. limit of parameter 1912 would even-
tually be reached.
