Design
Note When connecting to a digital controller or temperature controller with a voltage output, use a
3G3JE model with a PNP input. If a model with an NPN input is used, the power supply may be
short-circuited depending on the insulation method between the controller's voltage output sec-
tion and the power supply for other control input circuits.
Digital Controller and Temperature Controller Settings
■
• Set the control period as shown below for digital controllers and temperature controllers.
• If the control period is set shorter than the lower limit or longer than the upper limit, correct opera-
tion will not be possible.
Control period lower limit
Control period upper limit
3G3JE Settings
■
• Set the frequency reference upper limit (P07) and frequency reference lower limit (P08).
• Operation will be at the frequency reference lower limit with the time-shared proportional pulse at
0%.
• Operation will be at the frequency reference upper limit with the time-shared proportional pulse at
100%.
Note If the frequency reference upper limit is greater than the maximum frequency, change the
setting of the maximum output frequency (P06).
• Set the frequency reference selection (P11) is set to time-shared proportional pulses (T.C).
