8-2-16 Output Frequency Does Not Reach Frequency Reference
• The frequency reference is within the jump frequency range.
If the jump function is used, the output frequency stays within the jump frequency range.
Make sure that the jump width settings in n083 through n085 for jump frequencies 1 through 3 and
jump width in n086 are appropriate.
• The preset output frequency exceeds the upper-limit frequency.
The upper-limit frequency can be obtained from the following formula.
Maximum frequency in n011 × frequency reference upper limit in n033/100
Make sure that the parameters in n011 and n033 are correct.
8-2-17 Inverter Does Not Run Because EF (Simultaneous Inputs
of Forward and Reverse Commands) is Detected, Or
Motor Rotates Momentarily When Control Device Power
is Turned OFF
H Sequence Error
An EF will be detected if a forward command and a reverse command are input simultaneously for 0.5
seconds or longer. Correct the sequence.
H Malfunction Due to Unwanted Current Path
Inverter inputs may remain ON due to an unwanted current path for the controller outputs. With the wir-
ing shown in the following table, if the controller output power supply is less than 24 V DC or if the power
is OFF, the current indicated by the arrow will flow and the Inverter inputs will operate. If that occurs,
insert a diode as shown in the diagram at point A.
