3.26.3.3 Outputs
Name
Permitted type
Description
Error
safeBOOL
BOOL
Error output
TDC
safeBOOL
BOOL
Boolean output TDC is set if the current position is between
TDCx_LowerLimit and TDCx_UpperLimit.
BDC
safeBOOL
BOOL
Boolean output BDC is set if the current position is between
BDC_LowerLimit and BDC_UpperLimit.
CamMonOK
safeBOOL
BOOL
If all internal checks are without error, the CamMonOK output is
set. When the group in which the function block is programmed
is started, CamMonOK is set for the first time when a falling edge
is detected at the Reset input.
UpwardsMove
safeBOOL
BOOL
The output UpwardsMove is set to logical 1 between
BDC_UpperLimit and 0°.
OverrunTDC
analog
Difference between TDC1_LowerLimit and current position
OverrunStop
analog
Difference between position at falling edge at input
Press_Started and current position
3.26.3.4 Parameter
Parameter
Description
AllowedPositionJitter
The analog position value may jitter somewhat even at standstill; this jitter
is indicated with AllowedPositionJitter.
StopDetectionTime
Since the position is usually received via a TwinSAFE connection, its
value will not change in each cycle. For standstill detection the timeframe
(StopDetectionTime) must therefore by specified, within which the position
must only change around the AllowedPositionJitter.
PressStartDelayTime
If the input PressStarted is active, the time must be specified after which a
motion must be detected when PressStarted has a positive edge.
MoveDetectionTime
If the input PressStarted is active, the time must be specified after which
the position must change when a motion was detected for the first time.
MinPositionChange
If the input PressStarted is active, a value must be specified to indicate
the minimum position change within the MoveDetectionTime
MaxPosition
The parameter MaxPosition is used to set the maximum permitted position
value during a 360° movement of the press.
Pendulum Mode
Checkbox for activating pendulum mode
Excentric Mode
Checkbox for activating excentric mode
