SIMOTION D4x5-2 onboard outputs (interface X142)
The D4x5-2 onboard outputs can be used as cam output (CAM) from the user program. The
D4x5-2 onboard outputs are permanently assigned to SIMOTION. The X142 I/Os are
configured using HW Config.
The X142 configuration screen form can be accessed directly from the project navigator in
SIMOTION SCOUT.
With SIMOTION D4x5-2, output cams are output at the X142 interface with a resolution of 1
μs.
TM15 / TM17 High Feature Terminal Modules
The TM15 and TM17 High Feature Terminal Modules can be used to set up cam outputs (CAM)
within the SIMOTION Motion Control system. The Terminal Modules are connected directly to
SIMOTION D or CX32/CX32-2 via DRIVE-CLiQ for this purpose.
Alternatively, TM15 and TM17 High Feature can be connected to a SINAMICS S120 CU320/
CU320-2/CU310/CU310-2 Control Unit with higher-level SIMOTION C, P or D.
Output cams on the TM15 operate with DRIVE-CLiQ cycle-clock resolution (typically 125 µs).
Output cams on the TM17 High Feature have a resolution of 1 µs.
If current controller cycle clocks other than 125 μs are used, the parameter calculations of the
drive must be taken over into the PG and the Fast IO configuration must be recreated when
using cam outputs on TM15/TM17 High Feature. (For more information, see chapter Current
controller cycle clocks <> 125 μs / use of output cams and measuring inputs in the TM15 /
TM17 High Feature Terminal Modules Commissioning Manual.)
High-speed digital output (DO)
The cam output is performed via onboard outputs of the SIMOTION CPU. The output is via a
hardware timer and the cam output is achieved with a resolution with respect to time < servo
cycle clock.
The time that it takes for the axis to reach the output cam switching position with reference to
the processing cycle is calculated by linear extrapolation. Calculated from the beginning of the
1st position control cycle, the output cam function is triggered by a hardware time when this
time is reached.
Hardware supported
The onboard I/O of the following CPUs is used:
● SIMOTION D4x5 (interface X122, X132), 8 high-speed cam outputs, as of V4.1 (the I/O
● SIMOTION D410 (interface X121), 4 high-speed cam outputs, as of V4.1 (the I/O channel
● SIMOTION C240, C240 PN (interface X1), 8 high-speed cam outputs
SIMOTION D410/D4x5 onboard outputs
Output cams are output via a high-speed digital output (DO).
