24V power supply for switches etc. maximum load: see page 8
16
Gear ratio 2
1
Synchronous operation; Program 2:
Gear ratio most significant bit
17
Gear ratio 2
0
Synchronous operation; Program 2:
Gear ratio least significant bit
18
Not used
19
Home run
Synchronous operation; Program 2:
Starts the homing.
20
GND
Ground for 24V, normally bridged with Terminal 39, but this can
be set to “OFF” by means of Switch SW4 on the control card.
27
Reset/Enable
Error reset on rising edge. To enable operation, this input must be
switched to “1”. “0” = motor coast.
29
Hold
Synchronous operation; Program 2:
The drive is held at a programmable, or the present speed.
Synchronous control is not activated.
32
Test run reverse
Speed/Pos –
Test run; Program 1:
Test run reverse 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.
