The motor does not rotate if the following commands are given. 
1)  An operation command is given while coast-to-stop command is output to the control terminals. 
2)  Both operation command FWD and REV are input. 
 
(2) When motor rotates but the speed does not change
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
In the following cases, change of motor speed is also restricted. 
1) Bias frequency (F18) setting value is large. 
2) Signals are input from both control terminals 12 and C1 and there is no significant change in the added value.   
    (When F01 is 3)  
3)  Load is excessive and stall prevention function is activated.

Built-in POT (VR)
 
Motor rotates but speed 
does not change.
 
Maximum frequency 
setting too low? 
Upper/lower frequency 
limiter activating?
 
Which frequency setting 
method is in use: built-in 
POT (VR), keypad panel, 
analog signal, or 
multistep frequency?
 
External wiring con-
nections between control 
terminals X1,X2,X3 - 
CM connected correctly? 
Frequencies for each 
multistep selecting fre-
quency different? 
Setting of accelera-
tion/deceleration time 
excessively long? 
Change setting to correct 
acceleration/deceleration 
time for load. 
Probable faulty 
drive or error be-
cause of noise, etc. 
Contact GE Fuji.
 
Change the setting 
frequency. 
Remedy wiring error.
 
Does the speed 
change when UP or 
DOWN key de-
pressed?
 
Can the frequency 
setting signal (0 to 
+10Vdc, 4 to 
20mAdc) be 
changed?
 
External wiring con-
nections between 
control terminals 
13,12,C1 - 11 cor-
rect? 
Replace faulty fre-
quency setting 
POT(VR) or signal 
converter as ap-
propriate.
 
Change the setting.

Analog signal
 
Does speed change when 
freq. setting POT(VR) 
turned clockwise or counter 
clockwise?
