This is the minimum ON/OFF time of the time proportioning cycle.
Attribute:
R/W
Digits:
7 digits
Number of data:
2 (Data of each channel)
Data range:
0 to 1000 ms
Factory set value:
0
Related parameters:
Proportional cycle time (P. 9-34), Output assignment (P. 9-50)
Function:
The minimum ON/OFF time of the proportioning cycle is used to prevent output
ON or OFF when the output is greater than 0 % or less than 100 %. This is useful
when you wish to establish a minimum ON/OFF time to prolong the life of the
relay.
