Control properties and performance features

With a few exceptions, the integrated drive control of SIMOTION D4x5‑2 and CX32‑2 has the
same control properties and performance features as the SINAMICS S120 CU320 control unit.
However, the following points must be particularly observed:
● SINAMICS Integrated and CX32‑2 have no basic positioner (EPOS). EPOS functionality
is provided by SIMOTION technology functions.
● A BOP20 basic operator panel cannot be connected to the SIMOTION D4x5‑2.
The following alternative options are available:
– Use of SIMATIC HMI devices (e.g. TP177B, configurable with WinCC flexible)
– Use of the SIMOTION IT web server: You can use a Web browser to access the standard
● Not all SINAMICS function modules are supported (e.g. the function modules free function
blocks, spindle diagnostics, and CAN are not supported).
● The SINAMICS Integrated of the SIMOTION D4x5‑2 does not support a reset via parameter
p0972. A reset via p0972, is only supported by CX32‑2 and SINAMICS Control Units. You
can use this method, for example, in the context of the implementation of modular machine
concepts to force a restart of the CX32‑2 controller extension (only required for versions <
V4.3). See also the
7.5.8 Current controller cycle clocks <> 125 µs / use of output cams and measuring
inputs
If current controller cycle clocks <> 125 µs are used, the parameter calculations of the drive
must be transferred to the PG when using cam outputs on the TM15 / TM17 High Feature or
for global measuring inputs, and FastIO configuration generated again.
A change of the current controller cycle clock may have effects on the sampling times of the
inputs/outputs on the drive side (e.g. TM15/TM17 High Feature, p4099 Sampling time of the
inputs/outputs).
Sampling times <> 125 µs occur in the following cases:
● For servo drives with manual change of the current controller sampling time (drive
parameters p0112 and p0115[0])
● For vector drives depending on the number of vector drives and with chassis units
depending on the device type used
● If only an infeed and no drives are connected to the drive unit, then the sampling time is
250 µs

7.5 Additional information on configuring the SINAMICS Integrated
diagnostics pages of the SIMOTION D4x5‑2 (diagnostics and alarm buffers, Watch
table, read/write SIMOTION variables and drive parameters, access protection, trace
function, etc.)
You also have the option of creating your own Web pages, in order for example to
visualize machine states and implement service functions. The SIMOTION D4x5‑2 web
pages can be accessed, for example, with a PC or PDA via Ethernet. Wireless access
is also possible in conjunction with WLAN.
