5.3.1.2 Outputs
Inputs – power unit – X2
A1 – forward start
(pin 2)
Turntable rotation
forward
is enabled.
Output A1 is switched on when input E1 is activated.
Output A1 remains switched on until the turntable has reached the
calculated switch-off angle in order to optimally come to a stop in
the 0-position.
A2 - backward start
(pin 4)
Turntable rotation
backward
is enabled.
Output A2 is switched on when input E2 is activated.
Output A2 remains switched on until the turntable has reached the
calculated switch-off angle in order to optimally come to a stop in
the 0-position.
Outputs power unit – X1
A3 – 0- position
(pin 8)
The output (A3) is switched on when the drive roller is located in
the defined lock movement position window of +/- 8 degrees.
The turntable is then in its basic position.
A4 – overrun forward
(pin 9)
Output A4 is switched on, if after a start
Forward
the turntable has
overrun the 0-position.
In reverse mode output A4 is also set when the turntable is in the
forward position and an incorrect activation occurs from the PLC;
0-position (A2=on) + position forward (A8=on) + forward start
(A1=off). If the PLC then switches forward start on (A1=on) again,
the fault overrun forward (A4=on) will be set. The output 0-position
(A2) continues to remain set. If the input forward start (A1) is
switched off, then the fault overrun forward (A4) will be switched off
again.
NOTE!
If the fault occurs you
must follow
the instructions in
section -> 6.2.1
Overrun forward / backward.
