WT08HH - Omron R88D W-series servo drive

Documented system role for WT08HH, with source-backed evidence and explicit installation boundaries.

Documented function

Rebuilt from individual evidence

System position

Unknown: Evidence boundary

Omron documentation identifies WT08HH as an R88D W-series servo drive model.

Controls motion commands and provides servo motor output terminals.

The quick-start guide lists WT08HH with a 90 mm by 160 mm by 180 mm case and a 15 A upstream filter rating.

Sits between the motion controller and the matched servo motor in the servo system.

Provides controlled electrical output to the matched servo motor.

Unknown: The installed system configuration, firmware, wiring, and environmental conditions for WT08HH are not established by the captured sources.

System role

This section explains what the product does and where it acts in the surrounding system.

Function
Controls motion commands and provides servo motor output terminals.
System position
Sits between the motion controller and the matched servo motor in the servo system.
Upstream / inputs
Receives motion commands and control signals from the upstream controller.
Downstream / outputs
Provides controlled electrical output to the matched servo motor.
Limitations
Unknown: The installed system configuration, firmware, wiring, and environmental conditions for WT08HH are not established by the captured sources.

Evidence ledger

Facts, inferences, and unknowns are kept separate.

Facts

  • Omron documentation identifies WT08HH as an R88D W-series servo drive model.

    Confidence: high

  • The drive accepts motion command inputs and provides servo motor output terminals.

    Confidence: high

  • The quick-start guide lists WT08HH with a 90 mm by 160 mm by 180 mm case and a 15 A upstream filter rating.

    Confidence: high

Inferences

  • Sits between the motion controller and the matched servo motor in the servo system.

    Confidence: medium

    Rationale: The cited product function and communication or control interface establish this system position.

  • Provides controlled electrical output to the matched servo motor.

    Confidence: medium

    Rationale: The documented display, operator, or drive interface supports this downstream system function.

Unknowns

  • Unknown: The installed system configuration, firmware, wiring, and environmental conditions for WT08HH are not established by the captured sources.

    Confidence: low

    Missing evidence: The installed system configuration, firmware, wiring, and environmental conditions are not established by the captured sources.
