External operation
Possible faults:
● The motor will not rotate.
– Check that the EXT lamp is lit. The external operation mode is valid when Pr. 79 = 0
(initial value) or "2". Use the PU/EXT key to change into the external operation mode.
– Check that wiring is correct. Check once again.
NOTES Change the frequency (0Hz) of the minimum value of potentiometer (at 0V, initial value) by
adjusting the frequency in calibration parameter C2 "Terminal 2 frequency setting bias fre-
quency". (Refer to section 6.20.5.)
When you want to compensate frequency setting, use terminal 1.
