NOTES
One of Pr. 178 to Pr. 184 "Input terminal function selection" must be set to "4" (AU signal) (initial
value). (Refer to section 6.10.1.)
Change the frequency (50 Hz) at the maximum value of potentiometer (at 20 mA) by adjusting the
frequency in Pr. 126 "Terminal 4 frequency setting gain frequency". (Refer to section 5.3.6).
Change the frequency (0 Hz) at the minimum value of potentiometer (at 4 mA) by adjusting the
frequency in calibration parameter C5 "Terminal 4 frequency setting bias frequency". (Refer to sec-
tion 6.16.3.)

Acceleration constant speed
Perform 20 mA input. The frequency value on the
indication increases according to Pr. 7
"Acceleration time" until 50 Hz is displayed.
햶
Deceleration
Perform 4mA input. The frequency value on the
indication decreases according to Pr. 8
"Deceleration time" and displays "0.00" (0.00 Hz)
when the motor is stopped.
"RUN" flickers fast.
