Error Cause
• The PLC ready flag (M2000) was turned
OFF while positioning was being started in
response to a start request issued by a
sequence program.
• The PLC ready flag (M2000) was turned
OFF during a zeroing operation.
• The stop command (M1800+20n) has been
turned ON during a zeroing operation.
• The rapid stop command (M1801+20n) has
been turned ON during a zeroing operation.
• The PLC ready flag (M2000) was turned
back ON during deceleration initiated by
turning OFF the PLC ready flag (M2000).
• While a zeroing operation was in progress,
an emergency stop was executed in the test
mode at a peripheral device by pressing the
[Back Space] key.
• The feed current value exceeded the stroke
limit during positioning.
In the case of circular interpolation, an error
code is stored only for axes whose feed
current value exceeded the stroke limit.
In the case of linear interpolation, error
codes are stored for all axes involved in the
interpolation.
• During circular interpolation or during
simultaneous operation of multiple manual
pulse generators, the feed current value of
another axis exceeded the stroke limit value.
(For detection of other axis errors).
• An overrun has occurred because the set
travel value exceeds the deceleration
distance when a speed/position change
(CHANGE) signal is input during
speed/position switching control, or when
the proximity dog signal is input during
count type zeroing.
• During speed/position switching control, the
set travel value exceeds the stroke limit
when a speed/position switching (CHANGE)
signal is input.
