<Setting>
( 1 ) Set the time unit for programmed operation in Pr. 200. Select either of "minute/second" and
"hour/minute".
Setting
0 Minute/second unit (voltage monitor)
1 Hour/minute unit (voltage monitor)
2 Minute/second unit (reference time of day monitor)
3 Hour/minute unit (reference time of day monitor)
Note: 1. When "2" or "3" is set in Pr. 200, the reference time-of-day monitor screen is displayed
instead of the voltage monitor screen.
2. Note that when the Pr. 200 setting is changed, the units for Pr. 201 to Pr. 231 setting will
change.
(2) The inverter has an internal timer (RAM). When the reference time of day is set in Pr. 231,
programmed operation is started at this time of day.
1 ) Setting range
The time unit depends on the Pr. 200 setting.
Pr. 200 Setting
0 Maximum 99 minutes 59 seconds
1 Maximum 99 hours 59 minutes
Note: The reference time-of-day timer returns to "0" when both the start signal and group select signal
are entered. Set the reference time of day in Pr. 231 when both signals are on.
2) Resetting the reference time of day
The reference time of day is cleared by switching on the timer reset signal (STR) or by resetting
the inverter. Note that the reference time-of-day value set in Pr. 231 is also reset to "0".
( 3 ) Program setting
The rotation direction, running frequency and start time of day can be set by using Pr. 201 to Pr. 231.
