Setting Output Specifications Section 4-2
Note Control responsiveness improves as the control period is short-
ened, but if relays are being used for heater control, the relay life-
time will also be shortened so we recommend using a control
period of at least 20 seconds.
Note This parameter can be set only when operation is stopped. If the parameter is
set to 0, the period will be 0.5 s.
4-2-3 Output ON Scheduling Function
The ON time for each output can be reduced to one half or one fourth of the
control period to limit the number of outputs in the Unit that are ON simulta-
neously.
Note When the MV is assigned to an output, the actual limit is either this value or
the MV limit value, whichever is lower.
Note (1) When this parameter has been changed, the new setting becomes effec-
tive the next time a software reset is performed for the Unit or the next
time power is turned ON.
(2) Set the Delay between Outputs parameter to an even number. If an odd
number is set, the next smaller even number will be used.
!Caution
• Set the Output Mode Selection parameters to Standard Control for all of the
Unit's channels. The Output ON Scheduling function will be disabled if the
parameter is not set to Standard Control.
• Even if the Output ON Scheduling Method is set, the outputs may be ON at
the same time due to the delay in the output device's operation. In this case,
you can prevent the outputs from being ON simultaneously by setting a
delay with the Delay between Outputs parameter. Refer to the following set-
ting examples for details on using the delay.
