16#1605
Counted result in the latched
area is not retainable (major
error)
ON
The counter
module stops
operating and
counting
The error alarm makes the CPU
stop the system. (The module need
be set to keep counting or stop for
when an error occurs in the module:)

16#1800
Counter overflow / underflow
on CH1
Blinking
Linear counter:
Counting stops.
Ring counter:
Counting
continues.
Linear counter:
Counter value overflow inside the
hardware
Ring counter:
After the Ring Counter
Overflow/Underflow Detect function
is enabled in the Alarm Setting of
HWCONFIG, the alarm will appear
when the overflow or underflow
occurs.
16#1801
Counter overflow / underflow
on CH2
16#1802
Linear count exceeding the set
upper/lower limit on CH1
Blinking
The counting value
is fixed at the set
max. counter value
or the set min.
counter value.
The counting inside the hardware
persists. When the internal counter
value is back within the valid range,
the counter returns to normal and
the counting value is refreshed.
16#1803
Linear count exceeding the set
upper/lower limit on CH2
16#1804
The variation in relation to an
SSI encoder position
exceeding the limit on CH1
Blinking
The counting value
is fixed at the most
recent correct count
value.
The variation between two
consecutive SSI positions exceeds
the setting value.
16#1805
The variation in relation to an
SSI encoder position
exceeding the limit on CH2
16#1806
Abnormal SSI communication
on CH1
Blinking
The counting value
is fixed at the most
recent correct count
value.
Encoder disconnection/ wiring

consecutive abnormal situations
occur.)
16#1807
Abnormal SSI communication

16#1808
SSI absolute position cross
zero point on CH1
Blinking Counting continues.
After the SSI Zero Crossing Detect
function is enabled on the Alarm
Setting tab page of the HWCONFIG
software, the alarm will appear as
the absolute position of the SSI
encoder crosses the zero position.
16#1809
