Programming Notes (KRL basics)
- KRL structure: DEFDAT (data), DECL (declarations), BAS (basic), PTP/LIN/CIRC motion commands, WAIT, IF/ELSE, LOOP constructs.
- Example motion command:
PTP HOME Vel=100 %; LIN X 500, Y 0, Z 300 C_DIS; - Use frames and base/tool transformation to program in task coordinates.
- Use I/O read/write functions for peripheral control (e.g., SetDO, GetDI).
1. Ultra-Compact, Modular Hardware Design
Form Factor:
- Extremely small footprint: ~295 mm x 115 mm x 279 mm (depending on configuration).
- Can be mounted horizontally, vertically, or directly on a machine frame.
- Weight: approx. 10–14 kg (no external cooling unit required).
Integration Concept:
- “All-in-one” drive system with integrated servo drives for up to 6 axes (plus auxiliary axes).
- Central power supply (230 V or 480 V AC input) with internal 24 V DC power for electronics.
- No separate cabinet needed – can be embedded directly into small machines or mobile platforms.
Part 7: Alternatives and Updates (Manual vs. Reality)
KUKA is continuously improving the KR C5 micro. Be aware that the printed manual may lag behind:
- As of 2025: KUKA released a firmware update (KSS 8.7.5) that supports OPC UA FX (Field eXchange). The original manual from 2022 does not include these configuration steps. You must download the Supplement Sheet from KUKA Xpert.
- Second hardware revision: Early KR C5 micro units had a micro-USB service port. The manual for Rev B shows USB-C instead—double-check your board revision.
Safety Notes (summary)
- Always verify safety interlocks and emergency stop functionality before operation.
- Lock out/tag out power when performing maintenance.
- Keep personnel clear of robot swing envelope during automatic operation.
- Follow manufacturer instructions for safety-rated wiring and configuration.
Chapter 1: Safety (Do Not Skip)
The manual begins with a harsh warning: “Danger to life if ignored.” Key takeaways:
- Stop categories: 0 (uncontrolled) and 1 (controlled) stops.
- Residual risks: The KR C5 micro uses a switched-mode power supply that holds high voltage for up to 5 minutes after disconnection.
- EMC requirements: The manual specifies minimum distances from high-power cables (e.g., welding transformers).
