Lit during normal operation.
Hardware error, or PC notified of PCU error.
An error has occurred.
No error has occurred.
An error has occurred IN the CPU Unit.
No error has occurred at the CPU Unit.
Either a CW/CCW limit signal or an emergency stop input signal is being input. At
this time the LED indicator for the relevant axis (X to U) will flash.
Either a parameter loss, a data loss, or an operating data area designation error
has occurred.
None of the above has occurred.
Data is incorrect (e.g., the parameters or positions transferred are out of the
permissible range). At this time the LED indicator for the relevant axis (X to U)
will flash.
The check of all data (parameters, positions, etc.) following power up shows that
data is lost or corrupted.
None of the above has occurred.
Pulses are being output to the X axis (either forward or reverse).
An error has occurred, such as incorrect cable type for the X axis or faulty data.
None of the above has occurred.
Pulses are being output to the Y axis (either forward or reverse).
An error has occurred, such as incorrect cable type for the Y axis or faulty data.
None of the above has occurred.
Pulses are being output to the Z axis (either forward or reverse).
An error has occurred, such as incorrect cable type for the Z axis or faulty data.
None of the above has occurred.
Pulses are being output to the U axis (either forward or reverse).
An error has occurred, such as incorrect cable type for the U axis or faulty data.
None of the above has occurred.
Note For details regarding errors, refer to Section 11 Troubleshooting.
• For the CS1W-NC113/NC133, this applies only to the X axis; for the CS1W-
NC213/NC233, it applies only to the X and Y axes.
• When not all of the axes are used for the CS1W-NC213/NC233/
NC413/NC433, either connect the CW/CCW limit inputs for the unused axes to
the input power supply and turn them ON or set the contact logic to N.O. Con-
nect the emergency stop to the input common and turn it ON. If it is not con-
nected, the ERC indicator will light. Operation will be normal, however, for all
axes that are used.
This switch sets the unit number (i.e., the machine number) for the PCU as a
Special I/O Unit.
Memory is allocated to the PCU from the CPU Unit's Special I/O Unit Area
according to the unit number setting.
CS1W-NC113/NC133/NC213/NC233 models are allocated 10 words and
CS1W-NC413/NC433 models are allocated 20 words. The following unit num-
ber settings are possible:
• CS1W-NC113/NC133/NC213/NC233: 0 to 95
