3.5 Function parameters
SIMOTION ADI4 - Analog Drive Interface for 4 Axes
54 Manual, 05/2009, 6FC5 297-0BA01-0BP6
3.5.11 Boundary conditions
Measuring input or on-the-fly measurement
ADI4 supports only measurement using a rising or falling edge of the measuring input. It is
not possible to parameterize simultaneous measurement on a rising edge and a negative
edge.
Actual speed
The actual speed value (PZD2/3: NIST_B) contained in Standard message frame 3 (see
table "Message frame structure" in Section "
Message frame type (Page 37)") is not
supported by the ADI4. The ADI4 always sends the value "0" as the actual speed value.
External encoder interface (encoders without an axis)
If encoders are connected to the ADI4 without at least one axis being assigned, i.e. ADI4 is
used exclusively as an external encoder interface, a "Ready" signal (interface X6-1,
Pin 10/11) will not be output. For information on the "Ready" signal, refer to Section
"
Interface (X6-1): Digital outputs (Page 21)".
Error 20005
In conjunction with an ADI4 DP slave, the following message is displayed when the
SIMOTION CPU switches from RUN to STOP mode:
● Error 20005: Device type: 1/2, log. address: x faulted. (Bit: 0, reason: 0x...)
The message can be ignored.
This message is automatically deleted by the system the next time there is a transition from
STOP to RUN mode.
Homing using external zero mark
Homing always occurs at a rising edge, irrespective of which external zero mark edge (rising
or falling) was selected for homing in SIMOTION.
