Product details
Product Overview
- TWDPTO220DT – PTO extension module with 2 output channels.
- Produces square wave pulses with programmable count and cycle time.
- Supports single pulse train or multi‑train profiles (e.g., stepper motor ramp up/run/ramp down).
- Open‑loop positioning; servo‑drive handles the position loop.

Expert Review
- Manager’s Insight: “Robust and reliable for stepper/servo applications. The open‑loop design simplifies wiring, and the 200 kHz output handles high‑speed positioning. Ideal for packaging, labelling, and pick‑and‑place machines.”
Applications
- Stepper motor speed/direction control.
- Servo drive pulse train input.
- Multi‑axis positioning (ramp up/run/ramp down).
- Conveyor indexing and labelling systems.
FAQ
- What is the maximum output frequency?
200 kHz per channel (100 kHz in A/B phase mode).
- Can I use unshielded cables?
Shielded cables are strongly recommended for stable operation.
- How do I clear the counter?
Use the DRV_CLR digital output signal.
- Is the module hot‑swappable?
Yes, but ensure power is off when connecting cables.
- What if the actuator voltage drops below 14 V?
The monitor detects faults and triggers an alarm.
- Which servo drives are compatible?
Any drive accepting RS422 pulse/direction or CW/CCW signals.
- How to choose between PTO and PWM?
PTO is for positioning (pulse count); PWM is for speed/analog control.
- Can I extend cable length beyond 3 m?
Not recommended; signal integrity may degrade.
Selection Guide
- For single‑axis simple moves → use single pulse train mode.
- For multi‑segment profiles (e.g., trapezoidal) → use profile mode.
- Need feedback? Choose a closed‑loop servo drive instead.
- Check your drive input type: RS422 (differential) or open‑collector.
