KUKA KR C2 edition2005 Robot Controller Operation Manual

Top: If there is a top cabinet, additional space is required

Environmental conditions:

Operating temperature:+5 ° C to+45 ° C (without cooling unit),+5 ° C to+55 ° C (with cooling unit)

Storage temperature: -25 ° C to+70 ° C (without battery), -25 ° C to+40 ° C (with battery)

Humidity level: 3k3 per DIN EN 60721-3-3

Altitude: No derating required below 1000m, derating reduced by 5% for every 1000m below 4000m

7.2 Power Connection Requirements

KR C2 has strict requirements for power quality:

Electrical parameters:

Rated voltage: AC 3 × 400V to 3 × 415V

Voltage tolerance: 400V -10% to 415V+10%

Grid frequency: 49 to 61Hz

System impedance: ≤ 300m Ω

Rated power: Standard 7.3kVA, Heavy duty robot 13.5kVA

Fuse specifications: minimum 3 × 25A slow melting, maximum 3 × 32A slow melting

Important precautions:

Must be connected to the TN system (neutral point grounded)

It is necessary to rotate the magnetic field clockwise to ensure that the fan rotates correctly

System impedance exceeding 300m Ω may cause the fuse to fail to melt in a timely manner during ground faults

7.3 X11 Interface Configuration

X11 is a 108 pin Harting connector used to connect external security devices, and its correct configuration directly affects the security of the entire system

Key signal:

Drive open channel A/B (pins 11/12): Floating point contact, indicating the status of the drive contactor

Automatic mode contact (pin 48/46): Closed in automatic mode

Test mode contacts (pins 48/47): Closed during test mode

Verify input channels A/B (pins 50/51): STOP 0 triggered in all modes

If verification input is not used, pin 50 must be short circuited to test output 38, and pin 51 must be short circuited to test output 39, otherwise the system cannot operate.

Chapter 8: Maintenance and Fault Diagnosis

8.1 Preventive Maintenance Plan

The maintenance work of KR C2 must be carried out according to strict cycles:

Every 6 months:

Test the emergency stop button function

Test mode selection switch function

Check the direction of the external fan

Every 12 months:

Clean the interior of the control cabinet

Check and tighten all wiring terminals

Replace PC fan (based on running time)

Every 2 years:

Replace the control PC battery

Check the status of the pressure compensation plug

Every 5 years:

Replace the internal battery of KPS600

Replace the safety bus I/O terminal (safety bus system)

Regularly charge according to storage temperature:

≤ 20 ° C: Charge once every 9 months

20 ° C to 30 ° C: Charge every 6 months

30 ° C to 40 ° C: Charge every 3 months

8.2 LED Fault Diagnosis Guide

The LED indicator lights of each module in KR C2 provide first-hand information for rapid fault diagnosis:

KPS600 LED combination indicator:

LED1 flashes 5 times/1.5Hz: abnormal brake resistor current

LED1 flashes 4 times/1.5Hz: brake resistor fault

LED1 flashes 3 times/1.5Hz: DC bus overvoltage

LED1 flashes twice/1.5Hz: internal/radiator overheating

LED1 flashes once/1.5Hz: 24V power failure

KSD LED status:

Green constantly on: servo enabled, working normally

Green flashing: DC bus undervoltage (<250V)

Red flashing: Fault state (bus overvoltage)

Red green flashing: Communication error

CI3 board LED monitoring:

By monitoring the status of LED16-LED28, it is possible to monitor the 24V power supply, 5V ESC node, communication status of each node, and fuse status.

8.3 DSE-RDW diagnostic tool

DSE-RDW is a professional diagnostic tool provided by KUKA, which can deeply analyze the communication status between DSE and RDC:

Core diagnostic function:

Display DSE working status and DPRAM test results

RDC table displays measurement and configuration data for all axes

Communication error counter monitors transmission quality

Automatic adjustment of offset and symmetry

When the communication error counter continues to increase, it indicates interference in the connection between DSE and RDC, which may be due to poor cable shielding, poor contact, or EMC issues.

8.4 ESC Diagnostic System

The ESC diagnostic tool provides status monitoring and fault analysis functions for safety circuits:

Node status display:

Real time display of the status of each ESC node (CI3, KCP, KPS, MFC)

Dual channel signal consistency monitoring

Input/output signal level display

Fault record:

The error log is saved in C:  KRC  Robotter  Log  EscDiagnosis.rog

Record timestamps for all security related events

Support detailed configuration in expert mode

When a 'crossed connection error' occurs, it indicates that the A/B channels of the input signal are reversed or short circuited with the test pulse output, which is the most common wiring error in safety circuits.

Chapter 9: Safety Philosophy and Operating Standards

9.1 Risk assessment and protective measures

The security concept of KR C2 is based on a comprehensive risk assessment:

Definition of Hazardous Areas:

Workplace: Normal range of motion for robots

Dangerous area: workspace+stopping distance

Safe Zone: Outside the Dangerous Zone

Classification of protective measures:

Intrinsic safety design: mechanical limit, software limit

Protective devices: safety fence, grating, safety door

Warning devices: warning lights, buzzers, signs

Organizational measures: operating procedures, training, authorization
