<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
parameter unit).
3) Enter 30 (30Hz) and press the
4) Enter "4.30" and press the
5) Press the
key to move to the next parameter (Pr. 202), and press the
the FR-PU04 parameter unit) to display the current setting. Hereafter, press the
parameter one by one.
Note: 1. To make a stop, write "0" in the rotation direction and frequency. Set "9999" for no setting.
2. An error will result if 4.80 is entered (59 minutes or 59 s is exceeded).
• Assuming that operation has been programmed as indicated in the following table, the operation pattern is
as shown in the figure below:
