Error Content
No error.
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.
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.
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.
Operation command multiple selection error.
When several operation commands are simultaneously on in
b6, b8 to b15 of BFM#25, this error is output.
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.
Watchdog timer error.
Error corrective action
-
Set the maximum speed > the bias speed or the zero
return speed (high speed) > the creep speed and
execute error reset.
Change the positioning parameter set value to a value
within the set range and execute error reset.
Set the travel amount to a value within ±32 bit and
execute error reset.
Change the sequence program so that only one
operation command turns on, and execute error reset.
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.
If the error remains even when the power is turned from
OFF to ON, consult your local Mitsubishi Electric
representative.
