• Set the following values to Pr.52 Operation panel main monitor selection, Pr.774 to Pr.776 (Operation panel monitor
selection), Pr.992 Operation panel setting dial push monitor selection, Pr.54 FM terminal function selection and
Pr.158 AM terminal function selection for each monitor.

 Priority of main speed commands
• The priority of main speed command sources when the speed command source is External is as follows:
JOG signal > multi-speed setting signal (RL/RM/RH/REX) > 16-bit digital input (option FR-A8AX) > analog input (terminals
2)
• The priority of main speed command sources when "3" is set to Pr.79 Operation mode selection is as follows:
Multi-speed setting signal (RL/RM/RH/REX) > frequency setting (digital setting by PU or operation panel)
• Even if the remote operation function is selected by Pr.59 Remote function selection ≠ "0", compensation of the remote
setting frequency against the main speed is ignored. (The value is "0".)
• If the same terminal as an external input terminal having a speed command source (external terminal where a main speed
is input) is specified as the measured value input or set point input, the main speed is treated as "0".
• Setting Pr.73 ≥ 10 enables the polarity reversible operation when the PID manipulated amount is added to the main speed
command. (Polarity reversible operation of the main speed command without addition is not possible.)
 Adjustment procedure for dancer roll position detection signal
• When the input of terminal 4 is voltage input, 0 V is the lower limit position and 5 V (10 V) is the upper limit position (initial
values). When it is current input, 4 mA is the lower limit position and 20 mA is the upper limit position (initial values). When
the potentiometer has an output of 0 to 7 V, C7 (Pr.905) must be calibrated at 7 V.
20mA 5V(10V)
4mA
(Example) To execute control at the dancer center position using a 0 to 7 V potentiometer
1.
Switch the voltage/current input selection switch (switch 4) to "V", set "2" in Pr.267, and set terminal 4 input to
voltage input.
2.
Input 0 V across terminals 4 and 5, and calibrate C6 (Pr.904). (The % display that is indicated at analog calibration
is not related to the % of the feedback value.)
3.
Input 7 V across terminals 4 and 5, and calibrate C7 (Pr.905). (The % display that is indicated at analog calibration
is not related to the % of the feedback value.)
4.
Set Pr.133 to "50%".
