SMC20 – encoder evaluation (-B82)
Table 10- 7 Description of the LEDs on the SMC20
LED Color State Description
--- OFF The electronics power supply is missing or lies outside the permissible
tolerance range.
Green Steady light The component is ready for operation and cyclic DRIVE-CLiQ
communication is taking place.
Orange Steady light DRIVE-CLiQ communication is being established.
Red Steady light At least one fault is pending on this component.
Note:
LED is driven irrespective of the corresponding messages being
reconfigured.
Flashing, 0.5 Hz Firmware is being downloaded. Green Red
Flashing, 2 Hz Firmware download is complete. Waiting for POWER ON.
RDY
Green / orange
or
red / orange
Flashing, 2 Hz Detection of the components via LED is activated (p0144).
Note:
Both options depend on the LED status when module recognition is
activated via p0144 = 1.

Note:
Both options depend on the LED status when module recognition is
activated via p0144 = 1.
--- OFF Electronics power supply is missing or outside permissible tolerance
range.
Power supply ≤ 5 V.
OUT>5 V
Orange Steady light Electronic power supply for measuring system present.
Supply voltage > 5 V.
Notice:
You must ensure that the connected encoder can be operated with a 24
V supply.
Operating an encoder designed for a 5 V supply with a 24 V supply can
damage the encoder electronics beyond repair.
