JZRCR-XC001B

JZRCR-XC001B is a dedicated axis servo control board / servo driver unit originally designed for Yaskawa Motoman XRC series robot controller cabinet, upgraded revision based on base model JZRCR-XC001. It executes closed-loop servo motion control for robot joint axes, receives position command from main CPU board and feeds back encoder signal from robot servo motors. Widely compatible with classic XRC robot models: UP6, UP20, UP50, SK16X, SK45X, UP130, UP165, UP200 series 6-axis articulated robots. Available options: original new factory unit & fully tested used spare unit for robot maintenance replacement.

Description

1. Product Overview

JZRCR-XC001B is a dedicated axis servo control board / servo driver unit originally designed for Yaskawa Motoman XRC series robot controller cabinet, upgraded revision based on base model JZRCR-XC001. It executes closed-loop servo motion control for robot joint axes, receives position command from main CPU board and feeds back encoder signal from robot servo motors. Widely compatible with classic XRC robot models: UP6, UP20, UP50, SK16X, SK45X, UP130, UP165, UP200 series 6-axis articulated robots. Available options: original new factory unit & fully tested used spare unit for robot maintenance replacement.

2. Core Electrical Specs

  • Control power input: DC24V supplied by cabinet internal control power module

  • Rated applicable motor power: standard 400W servo motor matching specification

  • Feedback interface: multi-channel encoder input ports for incremental/absolute motor encoder signal

  • Built-in protection: overcurrent, overvoltage, overheat, position deviation error protection with corresponding alarm code output

  • External I/O terminal: multi-row plug-in terminals for servo enable, brake control, fault signal output between drive and cabinet backplane

3. Mechanical & Installation Info

  • Full nickel-plated metal shield housing for anti-electromagnetic interference inside robot cabinet

  • Standard DIN rail & screw fixed structure, fixed at dedicated slot inside XRC control cabinet; direct plug-in with backplane wiring without extra wiring modification

  • Net weight: approx 1.31kg, natural convection cooling via side ventilation slits, IP20 indoor cabinet-only installation

4. Compatible Matching Parts

Matches full XRC system accessories: XRC main CPU board, cabinet power supply unit, safety relay group, handheld teach pendant, external brake terminal block; XC001B is fully interchangeable with original XC001 base version on same robot cabinet.

5. Ambient Operating Condition

  • Working ambient temperature inside cabinet: 0℃ ~ +50℃

  • Storage temperature: -20℃ ~ +70℃

  • Humidity: 10%~85% RH non-condensation; avoid oil mist, corrosive gas, strong vibration and welding high-frequency EMI environment

6. Replacement Operation Steps

  1. Cut off robot cabinet total AC power and wait over 15 minutes to discharge residual high voltage inside the whole control system for electric shock prevention.

  2. Mark all plug-in terminal cables on XC001B sequentially then disconnect all connectors.

  3. Loosen fixing screws, remove faulty unit and install new replacement module in original position and fasten securely.

  4. Reconnect all terminals strictly following previous marking.

  5. Power on the cabinet, finish system self-check, jog single robot axes to verify no servo fault alarm and normal motor running.

7. Common Fault & Troubleshooting

  1. Robot axes cannot jog with servo ready alarm: Check DC24V control input power or internal fuse blown on XC001B board.

  2. Axis reports position deviation/overload alarm during operation: Inspect loose encoder wiring or damaged inner drive power circuit of the board.

  3. Individual motor brake fails to release: Check brake control output channel and corresponding terminal connection on the unit.

8. Safety Regulation

Strictly forbid hot plugging any signal/power terminals under powered state; instant surge voltage may permanently burn servo board and robot servo motors. Only certified industrial robot maintenance technicians are allowed to disassemble or repair internal circuit of this unit.
