Indicator
Color
RUN

Lit during normal operation. Goes out for errors.
XCW
Green
Lit during output of CW (clockwise) pulses for X axis.
XCCW
Green
Lit during output of CCW (counterclockwise) pulses for X
axis.
YCW
Green
Lit during output of CW (clockwise) pulses for Y axis.
YCCW
Green

axis.
ALARM
Red
Flashes if an alarm exists for the set data when the power
(flashing)
is turned on or when writing to EEPROM.
ERROR
Red
Lit when an error has occurred causing operation to stop.
• When the power is turned on, or when writing to EEPROM, the ALARM LED
flashes if data for X and Y within the assigned range is not entered in the re-
spective DM areas for the X and Y axes.
• When only one axis is used with the NC211 (two-axis control), short-circuit the
CW limit and CCW limit of the unused axis to 0 V in the input power supply. The
ERROR LED will light if these are not short-circuited, but the axis in use will
operate normally.
