(e) Timer setting value and timer limit setting
Set the timer to meet the following condition:
Timer setting value Scan time Timer limit setting
K2
(SD526,SD527)
T0
Figure 9.27 Relationship between timer setting value and timer limit setting
If the values are set to become "Timer setting value < Scan time + Timer Limit Setting", the coil and the contact
might be simultaneously turned on depending on the timing on which the coil is turned on.
If the setting does not meet the above condition, make the value of the timer limit setting smaller to meet the
condition.
Make the value of the timer limit setting smaller by changing from low speed timer to high speed
Example
timer. (Assume that the scan time is 20ms.)
After change (high-speed timer)
Before change (low-speed timer)
