The execution times are providedas a guide. External factors, button operations, execution of ZEN Support Software operations, and timing of the processing affects the actual processing times. The cycle timeis the sum of the common processing time, the processing time taken when Expansion I/O Units are connected, and the ladder program execution time.Common Processing TimeModelCommonprocessingtimeZEN-10C1AR-A0.85 msZEN-10C1DR-DZEN-10C2AR-A0.2 msZEN-10C2DR-DExpansion I/O Unit Processing Time0.15 ms/per Expansion I/O Unit.Ladder Program Execution Time25 m s*14 ms*2Timers (T)/Holding timers (#)15 m s*3Counters (C)10 m sDisplay bits (D)25 m sPer linePer outputCPU Unit output bits (Q)Expansion I/O Unit output bits (Y)Work bits (M)Holding bits (H)Weekly timers (@); per input3 msCalendar timers (*); per input2 msAnalog comparators (A); per input)1 msComparators (P); per input15 m s*4*5Example Calculation of Ladder Program Execution Time0001020304104I0I1I2[Q0Ladder program execution time =(25 ´ 5) + (4 ´ 3) + 15 + 3 + 15 = 170 (m s)Q0*5: P0I3[Q1*3: T0 (output)I4@0*4: @0TT0P0T0[Q2*2: Q (outputs) for 3 points*1:For 5 linesAppendix DApplication ExamplesLighting Pattern ControlApplicationThe ZEN can help conserve energy if the lighting patterns required for offices and similarenvironments are set to the ZEN.Use the switch operation to switch between lighting patterns.OperationSwitchLighting group1234(Q0)(Q1)(Q2)(Q3)All lights ONSW 1 (I0)ONONONONPattern 1SW 2 (I1)ONOFFONOFFPattern 2SW 3 (I2)ONONOFFOFFAll lights OFFSW 4 (I3)OFFOFFOFFOFFSystem ConfigurationAll lights ONPattern 1Pattern 2All lights OFFSW1SW2SW3SW4I0I1I2I3MC1MC2Lighting group 1 (Q0)Lighting group 2 (Q1)Lighting group 3 (Q2)Lighting group 4 (Q3)NCNote:Switches usemomentarynormally opencontacts.Q0 Q1 Q2 Q3MC1 MC2 MC3 MC4MC3MC4105Application ExamplesAppendix DProgram Example00 I0 (All lights ON)08 I2 (Pattern 2)01SQ0 Group 1 litSQ1 Group 2 lit02SQ2 Group 3 lit10SQ3 Group 4 lit110304 I1 (Pattern 1)SQ0 Group 1 lit05RQ106070912 I3 (All lights OFF)SQ0 Group 1 litSQ1 Group 2 litRQ2 Group 3 not litRQ3 Group 4 not litRQ0 Group 1 not lit13RQ1 Group 2 not litSQ2 Group 3 lit14RQ2 Group 3 not litRQ315Group 2 not litGroup 4 not litRQ3 Group 4 not litEscalator with Automatic Operation Function(Weekly Timer, OFF Delay Timer)ApplicationThe ZEN can be simply used to conserve energy for an escalator with an automaticoperation function.
The escalator can be set to operate continuously from 7:00 to 10:00and 17:00 to 22:00 weekdays and then operate at other times and on weekends onlywhen people step on the escalator.System ConfigurationRS T200 VACI0I1DC powersupply+I2–+–NCContactoror inverterQ0IM Escalator drive motor106Sensor to detect approaching personOperation switchStop switchZEN10C1DR-DAUse two weekly timers for the 7:00 to 10:00and 17:00 to 22:00 weekday operation.For the rest of the time, use an OFF delaytimer to operate the escalator for 3 minuteswhen pedestrians are detected.Application ExamplesAppendix DProgram Example00I1 Operates01 I2 Stops02 @0M0SM0RM0[Q0Escalator operatesTT0Off delay timer startsOperates 3 minutes after detection of person.03 @104 T005 I0 Person detected06Parameter SettingsWeekly timer @0(Mon to Fri: 7:00 to 10:00)Weekly timer @1(Mon to Fri: 17:00 to 22:00)OFF delay timer T0Water Supply Tank ControlApplicationBasic water supply control is possible with the 61F Switch (without float) alone, howeverrelay logic is required for inverter control of high-speed operation (when empty) andslow-speed operation (when half-full).107Application ExamplesAppendix DSystem ConfigurationR S T (200 VAC)I0L1I1I2L2NNC101161F-GP-N(For lower limit)101161F-GP-N(For half-full)101161F-GP-N(For upper limit)ZEN10C@AR-AInverter3G3FV S1Upper limitS5S6Water storage tankCOMIMHalf-fullLower- limitPump drivemotorPumpProgram Example00I2 Stop (upper limit)[Q0I0 (lower limit)I1 (intermediate)I0 (lower limit)I1 (intermediate)0102[Q1[Q2Inverter forward/stopInverter multistep speed command 1 (intermediate speed)Inverter multistep speed command 2 (high speed)Example: 3G3FV Inverter SpeedMotor speedFrequencyreference 2(intermediatespeed)Frequencyreference 1(low speed)Forward/stop (S1)Multistep speedcommand 1 (S5)Multistep speedcommand 2 (S6)108Frequencyreference 3(high speed)StopLow speedIntermediatespeedHigh speedApplication ExamplesAppendix DGreenhouse Air Circulation Control (1/3) (Bit Logicand Timer)ApplicationThe ZEN can be used to control circulation intermittently at set times.
This circulates thecarbon dioxide and warm air around plants in a greenhouse.In this example, two circulation fans are operated at set intervals. The starting current iskept to a minimum and, as a result, the circulation fans are set to start operating at different times.System ConfigurationR S T (200 VAC)ONL1OFFL2NSW1 (Operate)SW2 (Stop)NCZEN10C@AR-ASW1 (I0)SW2 (I1)Circulation fan 1MC1MC2IMT2T0T0T0Circulation fan 2MC1 (Q0)Circulation fanT1MC2 (Q1)IMCirculation fan 1 starts operation when the operationswitch is pressed. Circulation fan 2 starts operation 30seconds later.
The fans operate in a repeated cycle of 60minutes ON, 90 minutes OFF.Circulation fanProgram Example000102I0 OperateSM0I1 StopM0RM0T1[Q0 Fan 1 startsTT0 Startup time offset timer03T004T205T106[Q1 Fan 2 startsTT1 Operation timerTT2 Stop timer07109Application ExamplesAppendix DParameter SettingsOffset Start TimerSetting T0Operation timer setting T1Operation timer setting T2Set to 30 seconds.Set to 1 hour.Set to 1 hour 30 seconds.Greenhouse Air Circulation Control (2/3) (CalendarTimer and Weekly Timer)ApplicationThe ZEN can be used to operate circulation fans during winter nights only.In this example, the circulation fans operate only at night (19:00 to 6:00) during winter(November 15 to March 20).During the operation period, the fans operate intermittently, 60 minutes ON, 30 minutesOFF.
The low startup current results in a 30 second difference in the fan startup times.The start and stop operation days during winter (November 15 and March 20) are setusing the calendar timer (*0).The start and stop operation times during the night (19:00 and 6:00) are set using theweekly timer (@0).The startup time difference and operate/stop cycles are set using the timer (T0 to T2).110Application ExamplesAppendix DSystem ConfigurationR S T (200 VAC)ONOFFL1SW1 (I0) (Operate)SW2 (I1) (Stop)L2NNCZEN10C1AR-AMC1MC2MC1 (Q0)IMMC2 (Q1)IMCirculation fanCirculation fanProgram ExampleI0 Operates00SM0I1 Stops010203RM0M0*0M1T1@0[Q00607Fan 1 startsTT0 Startup time offset timer0405[M1T0T2T1[Q0Fan 2 startsTT1 Operation timerTT2 Stop timer difference count111Application ExamplesAppendix DParameter SettingsCalendar Timer Setting *0Weekly timer setting @0Start Nov 15 and stop Mar 20Start at 19:00 and stop at 6:00Offset startup time settingT0Operation time setting T1Stop time setting T2Set to 30 seconds.Set to 1 hour.Set to 30 minutes.Greenhouse Air Circulation Control (3/3) (AnalogComparator)ApplicationThe ZEN can be used to start the circulation fans once the temperature has reached aset level.
