Chapter 5 Specification of Parameters
There are three different center point modes when Y2/DO terminal is selected as high-speed
pulse output.
0: No center point.
DO pulse frequency output range 0~ (P23.09) corresponds to "0~maximum", as shown in Fig.
5-31:
Maximum corresponding value
1: Center point is (P23.09)/2, and the corresponding parameter value is positive when
frequency is higher than center point
center point is 0. DO pulse frequency P23.09 corresponds to the positive maximum value,
while DO pulse frequency 0Hz corresponds to the negative maximum value. See Fig. 5-32:
Maximum corresponding value
Maximum negative corresponding value
2: Center point is (P23.09)/2, and the corresponding parameter value is positive when
frequency is lower than center point. The value that corresponds to DO pulse frequency at
center point is 0. When set to 0, DO pulse corresponds to the positive maximum value, while
when set to P23.09, DO pulse frequency corresponds to the negative maximum value. See
