- Textile and woodworking machines
- General OEM drive systems
Frequently Asked Questions (FAQ)
- What is the maximum switching frequency of the digital outputs?The relay outputs are mechanical; switching frequency depends on load – typically ≤10 Hz for inductive loads.
- Can I use this control unit with a 480 V motor?Yes, as long as the Power Module supports the motor voltage. The CU240E‑2 PN‑F itself works with 24 V DC.
- Is the analog output isolated?No, the analog outputs are non‑isolated. Use proper shielding for noise‑sensitive signals.
- How many safety inputs can I configure?One fail‑safe input (uses two standard DI) – enough for basic safe torque off (STO) functions.
- Experience tip: Use shielded cables for analog signals and keep them away from power cables. This avoids interference and improves measurement accuracy.
- Selection guide: Choose this unit when you need PROFINET, 6 DI, 2 DO (relay), 2 AI, 2 AO and sensorless vector control. For encoder feedback, consider the CU250S‑2 or a higher‑end SINAMICS model.
