10-4 Troubleshooting
10
The motor rotation speed
does not increase.
The overload limit or
overcurrent suppression
function is active.
Disable the function, or increase the level at which
the function is activated.
7-72
7-75
The 1st/2nd/3rd Maximum
Frequency (A004/A204/A304)
or the 1st/2nd Frequency
Upper Limit (A061/A261) is
set too low.
Change the set value. 7-19
7-42
The set acceleration time is
too long.
Decrease the value set in the 1st/2nd/3rd
Acceleration Time 1/2
(F002/F202/F302/A092/A292/A392).
7-15
The Multi-function Input S1 to
S8 Selection (C001 to C008)
is set to 06 (JG: Jogging) and
that terminal is ON.
Turn OFF the terminal to which the function is
allocated.
7-108
The Multi-function Input S1 to
S8 Selection (C001 to C008)
is set to 02 (CF1) to 05 (CF4)
and that terminal is ON to
enable the Multi-step speed
setting.
Disable the Multi-step speed setting. When this
terminal is ON, multi-step speed operation is
enabled, so the motor rotates according to
frequency values set in the Multi-step Speed
Reference 1 to 15 (A021 to A035).
7-108
The load is too heavy. Reduce the load. –
The motor brake is applied. Release the brake.
The Output Frequency
Setting/Monitor (F001)
cannot be set via the
Digital Operator.
The Frequency Reference
Selection (A001) is set to
other than Digital Operator.
Set the Frequency Reference Selection (A001) to
02 (Digital Operator).
7-17
The Multi-function Input S1 to
S8 Selection (C001 to C008)
is set to 51 (F-TM: Forced
terminal block) and that
terminal is ON.
Turn OFF the terminal to which the function is
allocated.
7-108
The specified parameter
does not appear.
The Display Selection (b037)
is set to 01 (Individual display
of functions), 04 (Basic
display), etc.
Set the Display Selection (b037) to 00 (Complete
display).
7-78
The parameter settings
cannot be changed.
The inverter operates. Stop the inverter. Then, set the parameters again
after the motor stops decelerating. Setting b031 to
10 (Data can be changed during RUN) enables
parameter settings to be changed even when the
inverter operates.
–
The soft lock function is
enabled.
Disable the soft lock function in the Soft Lock
Selection (b031).
7-75
The motor rotates in
reverse.
The phase sequence of wiring
to the motor is incorrect. (The
motor is not designed to
rotate forward in the phase
sequence: U/T1, V/T2, W/T3.)
Reverse the order of two wires connected to U/T1,
V/T2, W/T3, or change the phase sequence to
match that of the motor.
2-14
The 3-wire input function is
enabled, but the
forward/reverse logic is
incorrect.
Check the logic of the F/R (3-wire forward/reverse)
signal allocated to a multi-function input terminal
(C001 to C008 = 22).
7-108
The motor rotates in
reverse when the RUN key
is pressed.
The RUN Direction Selection
(F004) setting is incorrect.
Set the RUN Direction Selection (F004) correctly. 7-16
