n S1-04: Voltage Restoration Complete LevelSets the level at which voltage restoration for the V/f pattern is complete as a percentage of the drive rated torque. If the outputtorque rises above the value of S1-04, then the voltage will be controlled in a manner specified by the V/f pattern setting.Note: Setting S1-04 to a value less than that of S1-03 + 10.0 will trigger an oPE02 error.No. Name Setting Range DefaultS1-04 Voltage Restoration Complete Level S1-03 + 10.0 to 100.0% 50.0%n S1-05: Voltage Restoration Sensitivity Time ConstantSets the level of sensitivity of the output torque as well as that of the LPF time constant for the voltage reduction rate. Thelevel of sensitivity can be adjusted in accordance with the load response.The LPF time constant is used to calculate the value of the output torque sensitivity time constant.The voltage reduction rate is based on the torque output. Select LPF to prevent voltage fluctuation.The Dynamic Audible Noise Control Function outputs the rate of voltage reduction as a percentage within the allowable range(Max: 100%, Min: S1-02 value).No. Name Setting Range DefaultS1-05 Voltage Restoration Sensitivity Time Constant 0.000 to 3.000 s 1.000 sn S1-06: Voltage Restoration Time Constant at ImpactSets the voltage restoration time constant if an impact load is added.Sets the time constant that enables the voltage level to rise if the speed suddenly changes upon impact.No. Name Setting Range DefaultS1-06 Voltage Restoration Time Constant at Impact 0.000 to 1.000 s 0.050 su S2: Sequence Timersn Programmable Run Timers for Real Time Clock (RTC)Programmable run timers allow the drive to start and stop automatically at specified times. The timers can be configured torun daily, on weekdays, on weekends, or only on specific days of the week.Sequence Timer 1When the current time reaches the value set in parameter S2-01 (Sequence Timer 1 Start Time), the drive will execute theaction set in parameter S2-04 (Sequence Timer 1 Selection), provided the current day is selected via S2-03 (Sequence Timer1 Day Selection). The drive will stop executing the S2-04 action when the S2-02 (Sequence Timer 1 Stop Time) is reached.When S2-04 = 0 or the Disable Sequence Timers multi-function input (H1-oo= 50) is closed, Sequence Timer 1 has no effecton the drive Run command. The drive runs normally based on the status of the selected run source (b1-02). If S2-04 = 1 or 2and the Disable Sequence Timers input is open, the drive will run during the Sequence Timer 1 active time, provided the drivehas a valid Run command. The frequency reference that is used is set by S2-05 (Sequence Timer 1 Reference Source). WhenS2-04 = 2, PI control is disabled.If the Cancel Active Sequence Timer multi-function input (H1-oo = 51) transitions from open to closed while SequenceTimer 1 is active, the timer will be disabled until the next scheduled sequence timer occurrence. Sequence Timer 1 can be re-enabled by cycling the drive Run command. The Sequence Timer 1 multi-function output (H2-oo = 50<1>) will close whileSequence Timer 1 is active regardless of the S2-04 selection.When S2-01 = S2-02, Sequence Timer 1 is active continuously for the days selected in S2-03. The timer will start at the S2-01/S2-02 time on the first day and stop at the same time on the last day. If only one day is selected in S2-03, the timer will stopat 24:00 on that day.When S2-04 = 1 or 2, Sequence Timer 1 is active and the drive is running, the HOA Keypad will display “Sequence Timer 1RUN”. When the drive has a run command, S2-04 = 1 or 2 and Sequence Timer 1 is not active, the HOA Keypad will display“Sequence Timer OFF”.When the drive has a run command, S2-04 = 1 or 2 and Sequence Timer 1 is not active, the drive should not fault on undervoltageor overvoltage conditions (should be Alarm only).<1> Details on this function can be found in the standard Z1000 Programming Manual (SIEPC71061645) atwww.yaskawa.com.5.12 S: Special ParametersYASKAWA ELECTRIC SIEP YAIZ1B 01E YASKAWA AC Drive – Z1000 Bypass Technical Manual 1875 Programming
