Servo Alarms

Bit 4

Negative Soft
Limit (SOTR)

Enabled when in the zero-point return completion
state (IBC0156 is ON), under conditions with the
axis selection as Linear and the negative direction
soft limit enabled.
This bit goes ON during motion command
(OWC020) interpolation
when the machine coordinate command position
(ILC018) + stopping distance (OLC026) negative
soft limit (fixed motion parameter no.29)
This bit goes ON when the machine coordinate
command position (ILC018) negative soft limit
(fixed motion parameter no.29) during positioning,
set speed feed, stepping, etc.

Bit 5

Unused

Bit 6

TIMEOVER

This goes ON if positioning completion (bit 13 of
IWC000) is not done even though the positioning
completion check time (OWC034) is exceeded
after feed completion (bit 2 of IWC015 is ON).

Bit 7

Positioning
Distance
Exceeded
(DISTOVER)

A motion command was executed in which the
positioning motion exceeded the limit value.

Bit 8 ~ 9

Unused

<Bit
1018>Bit
10

Control Mode
Error (MOD-
ERR)

ON when a motion command (positioning, set
speed feed, etc.) is set into Motion Command
(OWC020) in other than position control mode
(OBC0002 is OFF).

Bit 11

Zero-point Not
Set
(ZSET_NRDT)

ON upon attempting to execute the next motion
command in the zero-point setting completion sig-
nal (bit 3 of IWC015) OFF state.
POSING
EX-POSING
INTERPOLATE
ENDOF-INTERPOLATE
LATCH
Enabled when a rotary axis is set while using an
absolute encoder.

Bit 12~16 Unused

Bit 17

Excessive
Absolute
Encoder Rota-
tion

ON when the range in which absolute encoder
rotations can be handled by the motion module is
exceeded. Enabled when a rotary axis is set
while using an absolute encoder.

Bit 18

Encoder Dis-
connection
Error

ON when an encoder disconnection is detected.
Enabled when the fixed motion parameter “Pulse
Attribute Format Selection is set to A/B Type.
