On/Off Time
Each digital output has two user-controlled timers associated with it. The On
timer defines the delay time between a False-to-True transition (condition
appears) on the output condition and the corresponding change in state of the
digital output. The Off timer defines the delay time between a True-to-False
transition (condition disappears) on the output condition and the corresponding
change in the state of the digital output. Either timer can be disabled by setting
the corresponding delay time to zero.
PowerFlex 753 On/Off parameters noted below.
Depending on the PowerFlex 750-Series Option Module(s) installed, On/Off
parameters noted below.
Whether a particular type of transition (False-to-True or True-to-False) on an
output condition results in an energized or de-energized output depends on the
output condition. If a transition on an output condition occurs and starts a timer,
and the output condition goes back to its original state before the timer runs out,
then the timer is aborted and the corresponding digital output does not change
state.
Parameter No. Parameter Name Description
234 RO0 On Time Sets the “ON Delay” time for the digital outputs. This is the time between
the occurrence of a condition and activation of the relay.
235 RO0 Off Time Sets the “OFF Delay” time for the digital outputs. This is the time between
the disappearance of a condition and de-activation of the relay.
244 TO0 On Time Sets the “ON Delay” time for the digital outputs. This is the time between
the occurrence of a condition and activation of the relay or transistor.
245 TO0 Off Time Sets the “OFF Delay” time for the digital outputs. This is the time between
the disappearance of a condition and de-activation of the relay or
transistor.
Parameter No. Parameter Name Description
14 RO0 On Time Sets the “ON Delay” time for the digital outputs. This is the time between
the occurrence of a condition and activation of the relay.
15 RO0 Off Time Sets the “OFF Delay” time for the digital outputs. This is the time between
the disappearance of a condition and de-activation of the relay.
24 RO1 On Time or
TO0 On Time Sets the “ON Delay” time for the digital outputs. This is the time between
the occurrence of a condition and activation of the relay or transistor.
25 RO1 Off Time or
TO0 Off Time Sets the “OFF Delay” time for the digital outputs. This is the time between
the disappearance of a condition and de-activation of the relay or
transistor.
34 TO1 On Time Sets the “ON Delay” time for the digital outputs. This is the time between
the occurrence of a condition and activation of the transistor.
35 TO1 Off Time Sets the “OFF Delay” time for the digital outputs. This is the time between
the disappearance of a condition and de-activation of the transistor.
