Practically every function thatcan be controlled by a digital input can also be controlled by a Time Channel. Instead of havingan external PLC controlling a digital input you can program the "closed" and "opened"intervals of the input internally.NOTE! The functions of this parameter group can be made the fullest advantage of only if thebattery (option) has been installed and the Real Time Clock settings have been properly madeduring the Startup Wizard (see page 2 and page 3). It is not recommended to use thesefunction without battery backup because the drive’s time and date settings will be reset atevery power down if no battery for the RTC is installed.Time channelsThe on/off logic for the Time channels is configured by assigning Intervals or/and Timers tothem. One Time channel can be controlled by many Intervals or Timers by assigning as manyof these as needed to the Time channel.Figure 15. The intervals and timers can be assigned to time channels in a flexible way.Every interval and timer has its own parameter for assigning to a time channel.IntervalsEvery interval is given an "ON Time" and "OFF Time" with parameters. This is the daily timethat the interval will be active during the days set with "From Day" and “To Day” parameters.E.g. the parameter setting below means that the interval is active from 7 am to 9 am everyweekday (Monday to Friday). The Time Channel to which this Interval is assigned will be seenas a closed "virtual digital input" during that period.ON Time: 07:00:00OFF Time: 09:00:00From Day: MondayTo Day: FridayP9146.emfAssignToChannelInterval 1Interval 2Interval 3Interval 4Timer 1Timer 2Timer 3Interval 5TimeChannel 1TimeChannel 2TimeChannel 3
