<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
1
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 are defined as one point and every 10
points are grouped into three. The values can be set by using Pr. 201 to Pr. 231.
