Application-Specific FAQ
Q: Is the PD-4B compatible with Mitsubishi FX-series PLCs?
A: Yes. The step/direction pulse interface is directly compatible with FX3U/FX5U high-speed output modules. No additional signal converter is required.
Q: What is the maximum pulse frequency the PD-4B accepts?
A: Please refer to the official ALPHA datasheet or contact our technical team for confirmed electrical specifications for your application.
Q: Can I use the PD-4B in a servo-replacement retrofit?
A: The PD-4B is a stepper driver and is best suited for open-loop positioning applications. For closed-loop servo replacement, consider ALPHA’s servo drive series — contact us for a recommendation.
Q: Do you offer warranty on this module?
A: Yes. All units carry a 12-month warranty against manufacturing defects when operated within rated conditions.
Q: Can Konmask.com supply multiple units for a production line?
A: Absolutely. We handle OEM and MRO bulk orders. Contact us for lead time and volume pricing.
