<Setting procedure>
(Example: Set point No. 1, forward rotation, 30Hz, 4 hours 30 minutes)
1) Read Pr. 201 value.
2) Enter "1" (forward rotation) in Pr. 201 and press the [SET] key ([WRITE] key when using the FR-PU04
parameter unit).
3) Enter 30 (30Hz) and press the [SET] key ([WRITE] key when using the FR-PU04 parameter unit). (Note 1)
4) Enter "4.30" and press the [SET] key ([WRITE] key when using the FR-PU04 parameter unit). (Note 2)
5) Press the [UP] key to move to the next parameter (Pr. 202), and press the [SET] key ([READ] key when
using the FR-PU04 parameter unit) to display the current setting. Hereafter, press the [UP] key to advance
the parameter one by one.
Note 1: To make a stop, write "0" in the rotation direction and frequency. Set "9999" for no
setting.
Note 2: An error will result if 4.80 is entered (59 minutes or 59 seconds is exceeded).
