n S1-04: Voltage Restoration Complete Level
Sets the level at which voltage restoration for the V/f pattern is complete as a percentage of the drive rated torque. If the output
torque 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.
S1-04
n S1-05: Voltage Restoration Sensitivity Time Constant
Sets the level of sensitivity of the output torque as well as that of the LPF time constant for the voltage reduction rate. The
level 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.
S1-05
n S1-06: Voltage Restoration Time Constant at Impact
Sets 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.
S1-06
n S1-07: Output Phase Loss Level for Dynamic Noise Control
Reduces the output phase loss level when Dynamic Noise Control is active.
No.

S2: Programmable Run Timers

n 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 to
run daily, on weekdays, on weekends, or only on specific days of the week.
Sequence Timer 1
When the current time reaches the value set in parameter S2-01 (Sequence Timer 1 Start Time), the drive will execute the
action set in parameter S2-04 (Sequence Timer 1 Selection), provided the current day is selected via S2-03 (Sequence Timer
1 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= 51) is closed, Sequence Timer 1 has no effect
on the drive Run command. The drive runs normally based on the status of the selected run source (b1-02/b1-16). If S2-04 =
1 or 2 and the Disable Sequence Timers input is open, the drive will run during the Sequence Timer 1 active time, provided
the drive has a valid Run command. The frequency reference that is used is set by S2-05 (Sequence Timer 1 Reference Source).
When S2-04 = 2, PI control is disabled.
If the Cancel Active Sequence Timer multi-function input (H1-oo = 52) transitions from open to closed while Sequence
Timer 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) will close while
Sequence 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 stop
at 24:00 on that day. If "daily" is selected in S2-03, the timer will run from the start/stop time until 24:00 every day.
An S2-01 or S2-02 setting of 24:00 corresponds to midnight on the following day. For example, if S2-01 = 8:00, S2-02 =
24:00, and S2-03 = 9 (Saturday), Sequence Timer 1 will be active from 8:00 AM Saturday until 12:00 AM Sunday.
