The status of the SIMOLINK Encoder as regards SIMOLINK addressing
and pulse outputs is indicated via three green LEDs on the front panel.
The status of the SLE-DP encoder module can also be read out via the
PROFIBUS (cf. Section 6.4.6).

Description
Z-Pulse
†
Device not connected to supply voltage
No + 24 V supply voltage available
†
Supply voltage connected:
SYNC interrupt is not being received
’
DIL switch is incorrectly set:
Address switch is outside permissible range, SYNC and
Z-Pulse LEDs are flashing synchronously
†
SIMOLINK cycle time is not defined:
SYNC interrupt is outside 1.6 / 3.2 ms cycle
(251/502 telegram times, dispatcher mode)
†
SYNC interrupt is being received in the correct cycle:
SIMOLINK Encoder has not been activated or
setpoint telegram is not being received or
pulse output is not enabled via the control bit or
speed setpoint = 0 is being transmitted
l
Device is outputting signals
Z-PULSE LED is flashing in synchronism with zero pulse (appears
to be illuminated steadily at high speeds)
