Basic Information

• Model: JANCD-NTU30B (common suffixes: ‑1, ‑2)

• Alternate P/N: F352065‑1

• Revisions: C02, C03 (common)

• Manufacturer: Yaskawa Electric / Motoman Robotics

• Applicable controller: NXC100 series (only; not NX100/DX200)

• Function: Servo power ON/OFF control, interlock & contactor drive

• Origin: Japan

• Status: Active (new, refurbished, used available)

Technical Specifications

• Control supply: 24 VDC (from NXC100 backplane)

• Main power: 200–220 VAC three‑phase (to servo amplifiers)

• Fuses: Onboard fuses for control and power circuits

• Operating temp: 0–40 °C

• Humidity: 5–85 % RH (non‑condensing)

• Protection: Overcurrent, overvoltage, E‑stop & safety door interlocks

Key Functions

1. Servo power sequencing: Controls main contactors (KM1/KM2) to switch three‑phase power to servo amps in safe order.

2. Safety interlock: Enforces E‑stop, door open, mode conditions before enabling servo power.

3. Contactor drive: Drives coils of high‑power servo contactors.

4. Fault monitoring: Reports power‑on status and errors to the NXC100 CPU.

5. Voltage regulation: Stabilizes control voltages for logic and safety circuits.

Compatibility & Mounting

• Controller: NXC100 only (works with JANCD‑NCP30B (CPU), JANCD‑NSP30B (backup))

• Mounting: Installed in the NXC100 power supply section, connects to backplane and main contactors.

• Variants:

  • JANCD‑NTU30B: Standard NXC100 power sequence board

  • JANCD‑NTU30B‑2: Updated revision (component upgrades, C03)

  • JANCD‑NTU01: NX100 equivalent (different form/fit, not interchangeable)

Installation & Maintenance

• Cut all power (AC and 24 VDC) before service.

• Use ESD wristband to prevent static damage.

• Inspect fuses, contactor wiring, and interlock loops during service.

• Verify E‑stop and safety door functions after replacement.

• Service only by qualified technicians.
