Description
2.1 System overview
Typical applications include:
● Compact multiple-axis machines
● High-performance applications with short machine cycles
● Compact machines
● Distributed drive concepts
Versions
The control units are available in the versions SIMOTION D425-2 (BASIC performance),
SIMOTION D435-2 (STANDARD performance), SIMOTION D445‑2 DP/PN (HIGH
performance) and SIMOTION D455‑2 DP/PN (ULTRA-HIGH performance). The versions differ
in their PLC performance and in their motion control performance. The main distinguishing
features are:

● 0.5 ms in connection with SINAMICS S120 (incl. SINAMICS Integrated / CX32‑2)
● 0.25 ms (D455‑2: 0.125 ms) in connection with Servo_fast and IPO_fast for fast I/O
The control units feature PLC and motion control performance (open-loop control and motion
control) for up to 16, 32, 64 or 128 axes, as required.
The integrated drive computing performance of the control units allows up to 6 servo, 6 vector
or 12
≥ V4.x).
The drive control supports servo control (for a highly dynamic response), vector control (for
maximum torque accuracy) and
