Ext1 commands 20.1
0 No start or stop command sources selected. Not selected
1 The source of the start and stop commands is selected
by parameter
20.3 Ext1 in1 source . The state transitions
of the source bits are interpreted as follows:
In1 Start
Command State of source 1 ( 20.3 )
Start 0?1 ( 20.2 = Edge)
1 ( 20.2 = Level)
Stop 0
2 The source selected by 20.3 Ext1 in1 source is the start
signal; the source selected by 20.4 Ext1 in2 source
In1 Start; In2 Dir
determines the direction. The state transitions of the
source bits are interpreted as follows:
Command State of source 2
( 20.4 )
State of source 1
( 20.3 )
Stop Any 0
Start forward 0 0?1 ( 20.2 = Edge)
1 ( 20.2 = Level)
Start reverse 1
3 The source selected by 20.3 Ext1 in1 source is the
forward start signal; the source selected by 20.4 Ext1
In1 Start fwd; In2
Start rev
in2 source is the reverse start signal. The state
transitions of the source bits are interpreted as follows:
Command State of source 2
( 20.4 )
State of source 1
( 20.3 )
Stop 0 0
Start forward 0 0?1 ( 20.2 = Edge)
