I. Product Introduction

Brand: Yaskawa (Yaskawa)

Model: JANCD-JSP11 (Sub-model: JSP11-1, Revision B01)

Part Number: DF9202532-B0

Series: YASNAC J300 (Compatible with JCP10, JIF10, JMM01)

Function: Analog spindle control + Encoder position feedback + Positioning signal processing

Alias: J300 old spindle board, SP11 spindle control baseboard, Analog spindle board

Core purpose:

Control analog spindle (0–10V command), up to 12000 rpm

Receive incremental encoder (A/B/Z phases) feedback to achieve speed closed-loop and direction

Output spindle direction, gearshift, brake control signals

Compatible with early CNC lathes, vertical machining centers, drilling machines

II. Technical Specifications

1. Control Specifications

Spindle command output: Analog DC 0–10V, resolution 10bit, accuracy ±1.0%

Encoder feedback: Incremental A/B/Z phases, 5V differential, supports 1024–4096 ppr

Highest response frequency: 500kHz (incremental)

Control mode: Speed closed-loop, spindle direction (positioning accuracy ±0.1°)

2. Interface Terminals

CN1: Spindle command 0–10V + Enable / Fault I/O

CN2: Encoder feedback (A/B/Z, 5V differential)

CN3: Backplane bus (40-pin), connects JCP10 main control board

CN4: Spindle direction / Gearshift output (relay contacts, 250VAC/2A)

3. Electrical and Environmental

Power Supply: DC24V ±10%, power consumption approximately 10W

Size / Weight: Approximately 245×210×25mm, weighs 1.5kg

Operating Environment: Temperature 0–50℃, humidity 30%–85% (no condensation)

Isolation Voltage: I/O and system side AC1000V/1min

LED Indicators: PWR (Power), RDY (Ready), ERR (Fault), ENC (Encoder)

III. Differences from JSP02/JSP04

JSP11: Old analog spindle board, 0–10V, single axis, basic positioning, economy type

JSP02: Upgraded analog spindle board, higher accuracy (±0.5%), more stable direction

JSP04: MECHATROLINK-III bus, 4-axis联动， high-precision positioning， high-end application

IV. Installation and Wiring Tips

Installation： J300 cabinet Slot 4 (spindle slot)， anti-static， clean gold fingers.

Wiring： CN1 analog use shielded wire， single-ended grounding； CN2 encoder differential line should be away from power lines.

Self-check： Normal operation when PWR is constantly on， RDY flashes， ERR extinguishes.

Common Alarms：

ALM30： Backplane communication failure → Check CN3 cable， JCP10 power supply

ALM31： Encoder abnormal → Loose wiring， insufficient 5V power supply， encoder damage

ALM32： Spindle command abnormal → CN1 short circuit， analog output chip failure
