The ABB OTAC-01 user manual provides installation, wiring, configuration, startup, and diagnostic instructions for the pulse encoder interface module.
The OTAC-01 pulse encoder interface module connects a digital pulse encoder to an ABB ACS550 inverter, enabling precise speed and position feedback. The module is compatible with all ACS550 inverters and supports three encoder channels (A, B, Z).\n\nThe manual covers safety guidelines, step‑by‑step installation, wiring diagrams, encoder power requirements, channel configuration, and fault diagnosis. It also lists technical specifications such as input frequency, voltage range, and connector details. This manual is written in Chinese.
| Supported encoder channels | CH A, CH B, CH Z |
|---|---|
| Maximum input frequency | 200 kHz |
| Input voltage range | 7.5 – 26 V |
| Rated input impedance | 660 Ω (24 VDC) |
| Connector type | 6‑pin terminal |
| Maximum cable size | 1.5 mm² (16 AWG) |
The module supports a maximum input frequency of 200 kHz.
It accepts an input voltage between 7.5 V and 26 V.
No, the OTAC-01 does not supply power to the encoder; an external power source is required.
The module supports three channels: A, B, and Z.
