LED Indicators
Name Color Status Explanation
RUN Green Lit Lit during normal operation.
Not lit Hardware error, or PC notified of PCU error.
ERC Red Lit An error has occurred.
Not lit No error has occurred.
ERH Red
Lit An error has occurred IN the CPU Unit.
Not lit No error has occurred at the CPU Unit.
SENS Yellow Lit 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.
Flashing Either a parameter loss, a data loss, or an operating data area designation error
has occurred.
Not lit None of the above has occurred.
DATA Yellow Lit 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.
Flashing The check of all data (parameters, positions, etc.) following power up shows that
data is lost or corrupted.
Not lit None of the above has occurred.
X Orange Lit Pulses are being output to the X axis (either forward or reverse). g
Flashing An error has occurred, such as incorrect cable type for the X axis or faulty data.
Not lit None of the above has occurred.
Y Orange
Lit Pulses are being output to the Y axis (either forward or reverse).
g
Flashing An error has occurred, such as incorrect cable type for the Y axis or faulty data.
Not lit None of the above has occurred.
Z Orange Lit Pulses are being output to the Z axis (either forward or reverse). g
Flashing An error has occurred, such as incorrect cable type for the Z axis or faulty data.
Not lit None of the above has occurred.
U Orange
Lit Pulses are being output to the U axis (either forward or reverse).
g
Flashing An error has occurred, such as incorrect cable type for the U axis or faulty data.
Not lit 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
