Description
Reset during state transition to state 7. Counter is reset,
when the state has been reached.
Reset during state transition to state 8. Counter is reset,
when the state has been reached.
Reset signal source defined by parameter 8404 SEQ PROG
RESET
Selects the source for the Sequence programming state 1
reference. Parameter is used when parameter 1103 REF1
SELECT or 1106 REF2 SELECT is set to SEQ PROG /
AI1+SEQ PROG / AI2+SEQ PROG.
Note: Constant speeds in group 12 CONSTANT SPEEDS
overwrite the selected Sequence programming reference.
0136 COMM VALUE 2. For scaling, see Fieldbus reference
scaling on page 310.
Reference is calculated with the following equation:
REF = AI1(%) · (50% / AI2 (%))
Reference is calculated with the following equation:
REF = AI1(%) + 50% - AI2(%)
Reference is calculated with the following equation:
REF = AI1(%) · (AI2(%) / 50%)
Reference is calculated with the following equation:
REF = AI1(%) + AI2(%) - 50%

AI2 JOY
Analog input AI2 as joystick. The minimum input signal runs -0.5
the motor at the maximum reference in the reverse
direction, the maximum input at the maximum reference in
the forward direction. Minimum and maximum references
are defined by parameters 1104 REF1 MIN and 1105 REF1
MAX. See parameter 1103 REF1 SELECT selection
AI1/JOYST for more information.
