Error in
communication
from Slave
Normal output
During
communicating
with Master
- An error is found in
communication data from
Slave VS- 12PB.
1) Framing error
2) overrun error
3) Parity error
4) BCC error
(Check sum error)
5) Command error
(undefined command input)
6) END command mismatch
7) Answer data mismatch
- Correct the communication data.
20
Upper limit
overtravel
Operation
error OFF
In RUN and
TEST mode
- Current pos. value exceeds
upper limit.
- Move the machine back into the
lower limit to upper limit range.
- Correct the positioning setting
data.
- Correct the upper / lower limit
setting.
21
Lower limit
overtravel
- Current pos. value is below
lower limit.
22
Sensor error
System
Ready OFF
Always
- ABSOCODER sensor is
disconnected.
- Connect the ABSOCODER
sensor.
- Sensor cable is severed.
- Check the cable’s continuity.
- Wires inside ABSOCODER
sensor is severed.

Excessive
correction
amount
Operation
error OFF
- During
PRE operation
- During
machine
position check
operation
- ABSOCODER sensor
position deviation is caused by
machine slippage, backlash, etc..
- Deviation of the PRE (current
pos. preset) input signal reading
position.
- Incorrect “max. current amount”
setting (parameter setting)
- Incorrect “current position
preset value” setting.
- Adjust the machine.
- Re-designate the “max. correction
amount” parameter setting
(parameter No.66)
- Re-designate the “current position
preset value” parameter setting
(parameter No.71 to 74).
24
Excessive
current
position
change
Operation
error OFF
Always
- ABSOCODER sensor
rotation speed was detected in
each 20ms is too fast.
- Incorrect “max. current pos.
change” setting (parameter
setting)
- The ABSOCODER sensor
rotation exceeded the
absolute detection range.
- Check the ABSOCDER sensor’s
rotation (travel) speed.
- Re-designate the “max. current
pos. change” parameter setting
(parameter No.65).
