1.2 Core Main Functions

1. High-speed serial bus communication between main CPU(YCP series) and each servo amplifier(SRDA series); transmit motion command, position loop data, speed loop instruction in real time

2. Collect servo feedback data: actual motor position, motor current, servo fault codes, overheat, encoder abnormal signal, feed back to main CPU for operation judgment and alarm display

3. Process robot brake control signal, output servo enable, brake release instruction to each axis drive module

4. Transmit safety chain signal from YSF safety board to servo system, execute emergency stop, servo cutoff protection

5. Distribute system DC24V control power for internal servo peripheral circuits

2. Electrical & Environmental Specifications

4. LED Status Indicator Description

1. PWR(Green): Power indicator

   • ON: DC24V input normal; OFF: Fuse blown or backplane power abnormal

2. RUN(Green): System communication running lamp

   • Slow flashing: Normal communication with main CPU and all servo drives; Always OFF: Backplane bus fault or CPU communication lost

3. SERVO(Red): Servo system fault lamp

   • Steady ON: At least one servo drive communication break / servo alarm; Flash: Partial axis bus short-circuit or cable open circuit

4. SAFE(Yellow): Safety chain status lamp

   • ON: Safety loop closed, servo allowed to enable; OFF: E-stop pressed or cabinet safety door open, safety chain broken

5. DIP Switch Setting (S1 On PCB)

• No station address setting required (fixed core system board, address solidified inside controller firmware)

• BIT1: Servo bus terminal resistance setting: ON=enable terminal resistance (used when last servo on bus), OFF=disable

• BIT2~BIT4: Reserved factory setting, keep default OFF position, no modification allowed

6. Standard Installation Steps

Step1 Pre-operation Safety

Step2 Board Insertion

Step3 Servo Cable Wiring

Step4 Power On Confirmation

7. System Software Configuration

8. Common Troubleshooting

Fault 1: PWR LED always OFF

1. Check onboard 2A fuse burnout, replace with same specification fuse

2. Re-seat YIF01 board; test DC24V output of corresponding backplane slot

Fault2 RUN LED OFF, PWR normal

1. Poor contact between YIF01 and backplane gold finger, wipe gold finger with dry alcohol cloth and reinsert

2. Check main YCP CPU board working status

Fault3 SERVO RED LED steady ON, partial axis alarm

1. Inspect corresponding CN servo bus cable open/short-circuit, replace damaged shield wire

2. Check failed axis servo amplifier power supply status

Fault4 SAFE lamp OFF, servo cannot turn ON

10. Maintenance Precautions

1. All disassembly, wiring work must be completed under full power-off state

2. Every 6-month regular maintenance: Clean PCB surface dust, check connector terminals looseness and cable aging

3. For faulty board: Integral replacement recommended; non-professional disassembly of onboard components is prohibited
