11.2 Error Codes
When an error occurs, the error contents can be checked by the error code (BFM#29).
After removing the error cause, clear the error code by turning off the power supply or by error reset (BFM#25
b0).
*1. represents the BFM number for which there is an error.
Error code Error Content Error corrective action
K0 No error. -
K 1
*1
Speed relationship is incorrect.
When the high speed < the bias speed or the zero return
speed (high speed) < the creep speed is set and the
operation is started, this error is output.
Set the maximum speed > the bias speed or the zero
return speed (high speed) > the creep speed and
execute error reset.
K 3
*1
Setting range is incorrect.
When a value beyond the setting range is set to the
positioning parameter and the operation is started, this error
is output.
Change the positioning parameter set value to a value
within the set range and execute error reset.
K 4
*1
Setting value overflow error.
When the converted pulse value of the travel distance
exceeds ±32 bits (at the start of operation or while the target
address is changed), this error is output.
Set the travel amount to a value within
±
32 bit and
execute error reset.
K5
Operation command multiple selection error.
When several operation commands are simultaneously on in
b6, b8 to b15 of BFM#25, this error is output.
Change the sequence program so that only one
operation command turns on, and execute error reset.
K6
Forward limit/reverse limit error.
When the forward limit (BFM#25 b2) or the reverse limit
(BFM#25 b3) turn on, this error is output.
When the forward limit/reverse limit turns off, this error
is reset.
Move away from the forward limit/reverse limit by using
the JOG operation.
K7 Watchdog timer error.
If the error remains even when the power is turned from
OFF to ON, consult your local Mitsubishi Electric
representative.
