SMC20 – encoder evaluation (-A82)
Table 10-7 Description of the LEDs on the SMC20
LEDs Color Status Description
--- OFF The electronics power supply is missing or lies outside the
permissible tolerance range.
Green Continuous The component is ready for operation and cyclic DRIVE-CLiQ
communication is taking place.
Orange Continuous DRIVE-CLiQ communication is being established.
Red Continuous At least one fault is pending on this component.
Note:
LED is driven irrespective of the corresponding messages being
reconfigured.
0.5 Hz flashing light Firmware is being downloaded. Green/red
2 Hz flashing light Firmware download is complete. Wait for POWER ON.
RDY
Green/orange
or
red/orange
2 Hz flashing light 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.
SMC30 – encoder evaluation (-A81)
Table 10-8 Description of the LEDs on the SMC30
LED Color State Description
--- OFF The electronics power supply is missing or lies outside 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.
0.5 Hz flashing light Firmware is being downloaded. Green / red
2 Hz flashing light Firmware download is complete. Waiting for POWER ON.
RDY
Green Orange
or
Red Orange
2 Hz flashing light 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.
--- OFF Electronic power supply missing or outside permissible tolerance
range.
Measuring system supply ≤ 5 V (only when ready for operation).
OUT>5 V
Orange Steady light Electronic power supply for measuring system present.
Measuring system supply > 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.
