Safety function is enabled and either
GS1 or GS2 input is inactive.
Possible Cause(s)
"18:RS", "14:CS" or "11:FRS" is set to
input terminal and the input is active.
"84:ROK" is set to input terminal and
the input is active.
Cable between inverter and motor or
internal cable of motor is breaking.
Excess load.
Motor is locked.
3. Motor does not accelerate to command speed.
Possible Cause(s)
Bad connection of analog wiring.
Overload restriction or OC suppression
function works.
Max. frequency (A004) or upper limit
(A061/A261) is lower than as expected.
Acceleration time is excessive.
"Multi-speed input(s) (02 to 05:CF1 to
CF4)" is (are) set to input terminal(s)
and active.
"06:JG " is set to input terminal and the
input is active.
Excess load.
Motor is locked.
4. Inverter does not respond to changes in frequency setting from operator.
Possible Cause(s)
Incorrect frequency source is selected.
"51:F-TM" is set to input terminal and
the input is active.
5. A part of function codes is not displayed.
Possible Cause(s)
"Function code display restriction" (b037)
is enabled.
"86:DISP" is set to input terminal and
the input is active.
6. Operator (keypad) does not respond.
Possible Cause(s)
"86:DISP" is set to input terminal and
the input is active.
If safety function is used, activate both GS1 and GS2. If
not, disable safety function by dip switch.
Corrective Action
