Negative Software
Limit (SOTR)
This parameter is valid if IBC0156: Zero Point Return Com-
pleted turns ON when the negative software limit is enabled
and an infinite length axis is selected.

Limit (motion fixed param-
eter no. 29).
2. OWC020: Motion Command Codes Positioning, Feed,
or Step
This bit turns ON when ILC018: Reference Position in
Machine Coordinate System Negative Software Limit
(motion fixed parameter no. 29).

TIMEOVER
This bit turns ON if bit 13 of IWC000: Positioning Com-
pleted Signal does not turn ON when the Positioning Com-
pleted Check Time (OWC034) is exceeded after bit 2 of
IWC015: Distribution Completed is turned ON.
7
Over speed
This bit turns ON when the electronic gear’s limit is
exceeded.
8 to

10
Control Mode
Error (MODERR)
This parameter turns ON when a move command is set at
OWC020: Motion Command Code in a mode other than
Position Control Mode (OBC0002 is OFF).
11
Zero Point Not Set
(ZSET_NRDT)
This parameter turns ON when an attempt is made to execute
one of the following motion commands with the bit 3 of
IWC015: Zero Point Setting Completed Signal turned OFF.
• POSING
• EX-POSING
• INTERPOLATE
• ENDOF-INTERPOLATE
• LATCH
The parameter is valid if infinite length axis is set when an
absolute encoder is used.
12 to
13
Not used.

17
ABS Encoder
Count Exceeded
This parameter turns ON when the absolute encoder count
exceeds the range that the Motion Module can handle. The
parameter is valid if infinite length axis is set when an abso-
lute encoder is used.
