This document is an instruction sheet for the EME-A22A Analog Extension Card for the VFD-E Series. It provides information on installation, parameter settings, and specifications.
This instruction sheet provides the necessary steps to install the Delta EME‑A22A analog extension card on a VFD‑E series drive. It emphasizes that the drive must be powered off before mounting, the card should be fixed with the supplied screws, and torque values must be observed (2 kgf‑cm for the card, 5 kgf‑cm for terminals). Wiring guidelines include using shielded wires, keeping a minimum 15 cm separation from other control or power cables, and routing wires at 90° when crossing.
The document also lists the environmental limits, electrical characteristics, and safety notes. Operating temperature ranges from –10 °C to 50 °C, storage temperature from –20 °C to +60 °C, and humidity below 90 % RH. Electrical specs include a 0‑10 VDC input range, 12‑bit resolution, and recommended wire gauge of 14‑24 AWG. Safety recommendations cover the use of fuses, RC networks or varistors for inductive loads, and proper grounding of shielded cables. This manual is written in Chinese.
