Synchronizing controller
Test run; Program 1:
Test run forward at the speed defined in Parameter 725
Synchronous operation; Program 2:
In velocity synchronous mode (P. 725 = 0, 1, 6 or 7) the gear ratio
and thus the velocity of the slave can be changed by the value
specified in parameter 744.
In position synchronous and marker synchronous operation (P.
725 = 1, 2, 4 or 5), the position offset of the slave can be changed
by the value specified in Parameter 744. The sign of the value in
parameter 744 selects the offset type to be absolute or relative.
Absolute offset means that the fixed offset of parameter 742 is
changed and this offset is executed when restarting
synchronization.
Relative offset means that the actual slave position is displaced
but the fixed offset of parameter 742 is unchanged. This again
means that the actual slave position is maintained when restarting
synchronization. Relative offset 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 synchronization and the
min. or max. limit of parameter 742 would eventually be reached.
Relay output:
Function can be configured by means of Parameter 323.
Relay output:
Function can be configured by means of Parameter 326.
Ground for analogue inputs/outputs, normally bridged with
Terminal 20, but this can be set to "OFF" by means of Switch SW
4 on the control card.
The output value is scaled to maximum slave velocity (parameter
716); the signal type can be selected in parameter 319.
The output value is scaled to maximum slave velocity (parameter
716) multiplied by the gear ratio; the signal type can be selected
in parameter 321.
Power supply for reference value potentiometer
Serves as reference input for the virtual master if "0" is selected in
Parameter 748.
Synchronous operation; Program 2:
Serves as numerator for the gear ratio if "6" or "7" is selected in
parameter 725.
