Corresponding non-brake model: HG-KN23J-S100

✅ Replacement & Kompatibilitätshinweise

Cannot be directly used with MR-E, MR-J3, MR-J4 drives; only MR-JE series drives are supported

Inländische Alternative: Inovance ISMH1, Xinje MS5 series 200W servo with brake (inertia, flange and shaft diameter must be cross-checked)

✅ Common Fault Points

Missing 24V brake supply → Motor locked
Loose or broken encoder cable → ALM32 (encoder error)
Improper inertia matching → Vibration and overshoot
Aging oil seal → Oil leakage

MR-JE-A: Impuls + analog control; works with any pulse-output PLC / motion controller

MR-JE-B: SSCNETⅢ/H fiber bus; only compatible with Mitsubishi SSCNETⅢ/H simple motion modules, third-party bus masters are not supported

MR-JE-C: Ethernet bus (CC-Link IE Field Basic + Modbus TCP), CiA402 supported, wider controller options

This HG-KN23BJ-S100 motor works with MR-JE-20A / MR-JE-20B / MR-JE-20C. Below are recommended controllers sorted into Mitsubishi native solutions, third-party pulse controllers and third-party bus controllers:

Mitsubishi Native Solutions (Best compatibility, einfache Inbetriebnahme)

1) For MR-JE-B (SSCNETⅢ/H Fiber Bus)

✅ Simple motion modules are mandatory; built-in CPU pulse outputs cannot be used:

FX5-40SSC-S: For FX5U/FX5UC, bis zu 4 Achsen, am weitesten verbreitet

FX5-80SSC-S: For FX5U/FX5UC, bis zu 8 Achsen

QD77MS2 / QD77MS4 / QD77MS16: Q-series PLC (Q03UDV etc.)

LD77MS2/4/16: L-series PLC

RD77MS2/4/8/16: iQ-R series PLC

Merkmale: Fiber communication, good synchronization, elektronische Kamera, mark synchronization, Mehrachssynchronisation; suitable for printing, labeling and synchronized transfer mechanisms. SSCNETⅢ/H exclusive; incompatible with EtherCAT.

2) For MR-JE-A (Pulstyp, Differential / Open-collector Pulse)

Directly use Mitsubishi PLC with built-in pulse outputs, no extra motion module required:

FX3U: FX3U-16MT/32MT, built-in Y0/Y1 pulse (2 Achsen), for simple point-to-point positioning

FX5U / FX5UC: Eingebaut 4 high-speed pulse channels, max 200kHz, cost-effective for small machines

FX2N (altes Modell, nicht für neue Projekte empfohlen)

Q-Serie + QD75 positioning module: QD75D2/D4 (Impulsausgang), multi-axis positioning

MR-JE-A supports differential pulse up to 4Mpps. Differential output controllers are preferred.

3) For MR-JE-C (CC-Link IE Field Basic / Modbus TCP)

FX5U + FX5-CCLIEF (CC-Link IE Field Basic board)

iQ-R, Q-series PLC with CC-Link IE master module

Any Modbus TCP capable PLC can read/write servo registers for positioning control

Third-Party Pulse Controllers (For MR-JE-A only, kostengünstig)

Any controller supporting differential pulse (empfohlen) / open-collector pulse + direction is applicable:

Inovance H3U: Built-in high-speed pulse, bis zu 4 Achsen, mainstream domestic alternative to FX5U
Xinje XD5E/XD6: Pulse PLC, for standalone small machines
Delta DVP-ES2/SS2, DVP-10MC: Impulsausgang, common for legacy machine retrofits
Leadshine, Googol pulse motion control cards: PCIe / network pulse cards, for PC host-based solutions
Wecon, Fatek pulse PLC: Low-cost standalone positioning

Notiz: Differential pulse for MR-JE-A offers strong anti-interference; open-collector pulse is only for short wiring distances.

Third-Party Bus Controllers (For MR-JE-C only)

MR-JE-C supports CC-Link IE Field Basic, Modbus TCP, CiA402:

Inovance AC800, AM400 (with CC-Link IE Basic master)

Modbus TCP PLCs (Omron, Siemens S7-1200/1500, Xinje, Delta)

Motion control cards (Googol, Leadshine, Linghua): Positioning via Modbus TCP; synchronization performance weaker than native CC-Link IE

⚠️ Critical reminder: MR-JE-B does NOT support EtherCAT, Profinet or Modbus; only Mitsubishi SSCNETⅢ/H modules are allowed. This is a common pitfall.

Kurzanleitung zur Auswahl

Einzel / 2-axis simple positioning, begrenztes Budget: FX5U + MR-JE-A (Pulskontrolle)

Multi-axis applications requiring electronic cam, mark synchronization: FX5U + FX5-40SSC-S + MR-JE-B

Mix domestic PLCs without SSCNET fiber: MR-JE-C + Modbus TCP / CC-Link IE Basic supported PLC

Legacy machine retrofit with existing pulse controller: MR-JE-A

Mitsubishi Servo Motor Series + Fahren + Compatible Controller Master List

Important Preconditions

Servo motors must be matched to their corresponding drive series first. Drive interface type (A pulse / B SSCNETⅢ/H / GF CC-Link IE / C CC-Link IE Basic) defines available controllers. Motors cannot cross drive series (J5 motors cannot run directly on J4 or JE drives).
Pulse drives (MR-JE-A / MR-J4-A): Any differential pulse output PLC is compatible. Only Mitsubishi native options are listed below; third-party pulse PLCs (Inovance H3U, Xinje XD6, Delta DVP, Leadshine motion cards) are also usable.
SSCNETⅢ/H (Typ B): Only Mitsubishi SSCNETⅢ/H simple motion modules / motion CPUs. Third-party EtherCAT, Profinet masters cannot connect directly.
CC-Link IE (GF / C): Mitsubishi CC-Link IE master modules + third-party PLCs supporting CC-Link IE Basic.
Software: MR Configurator2 (J3/J4/JE), MR Configurator3 (J5), GX Works3, MT Works2
