YASKAWA CIMR-HB4A0112 Hoist Drive – Heavy‑Duty 400V Inverter for Cranes, Hoists, and Winches

The YASKAWA CIMR-HB4A0112 belongs to the H1000 hoist series, designed specifically for lifting applications that demand precise torque control, safe brake handling, and high overload capacity. From my experience, the “HB4A0112” code tells you two key things right away: it’s the 400V class (4A) and it’s typically a ~112 A rating in heavy-duty hoist service—often paired with 45–55 kW motors at 400 V, depending on duty cycle. If you’re retrofitting an older hoist panel, this model seems to drop in nicely with standard panel-mount practices and offers the hoist‑centric functions maintenance teams expect.

Our Order Placement Process and Guarantees

• Quotation & confirmation of model/specs.
• Payment terms: 50% advance payment; full payment before delivery.
• Lead time: typically 1 week if in stock; no more than one month at the latest.
• Shipment via FedEx, UPS, or DHL (express, trackable).
• Warranty period: 365 days.

Key Features

• Hoist‑specific control – Brake sequence management, torque proving, and pre‑excitation routines help prevent load slip when releasing the mechanical brake.
• Heavy‑duty overload – Designed for lifting cycles with high peak torque; typically up to 150% for 60 s and 200% for short bursts (3 s), so starts under load are confident.
• Reliable stopping and holding – Coordinated brake output and speed supervision minimize hook drift and keep loads steady during inching.
• Flexible feedback options – Open‑loop operation for induction motors, with optional encoder feedback cards for closed‑loop speed/torque regulation when needed.
• Built for integration – Standard RS‑485 Modbus‑RTU and optional fieldbus cards (EtherNet/IP, PROFINET, PROFIBUS‑DP, DeviceNet, CANopen, EtherCAT) make it easy to drop into existing PLC architectures.
• Braking and energy handling – Supports dynamic braking resistors or external regenerative units for frequent up/down cycles and fast deceleration.
• Environmental resilience – Operates in typical -10 to +40°C cabinets; derating provisions help in warmer enclosures with proper ventilation.
• Safety – Safe Torque Off (STO) capability is available on this series, commonly implemented as dual‑channel for SIL2/PL d architectures.

Technical Specifications

Application Fields

The CIMR-HB4A0112 is purpose‑built for vertical motion. Typical sites include bridge and gantry cranes, EOT cranes in steel and fabrication plants, port and logistics hoists, winches and trolleys, stage hoists, and warehouse lifting systems. You might notice that cycles with frequent starts/stops, inching, and load holding benefit the most from the H1000’s brake coordination and torque‑proving logic.

Advantages & Value for Procurement

• Reliability under hoist duty – Proven in lifting environments where thermal stress and shock loads are common.
• Compatibility – Works with standard 400 V induction motors; encoder options enable closed‑loop upgrades without redesigning the whole system.
• Cost control – Proper braking or regeneration selection can cut wear on mechanical brakes and reduce energy losses in repeated lowering cycles.
• Integration support – Fieldbus cards and typical Modbus‑RTU simplify PLC connectivity; parameter sets can be cloned for fast commissioning.
• Lifecycle serviceability – Spares, fans, and option cards are readily available in most regions.

Installation & Maintenance

• Cabinet & ventilation – Mount vertically in an IEC/UL compliant enclosure with adequate top/bottom clearance. In most cases, forced ventilation is needed above 40°C ambient or for high cycling.
• Wiring – Use properly sized 3‑phase supply and motor cables; segregate control wiring; bond PE/ground with low impedance. Fit line reactors/EMC filters when required by site standards.
• Braking hardware – Size dynamic braking resistors or regen units to suit decel time and load inertia. Thermal protection on the resistor is strongly recommended.
• Commissioning – Run motor autotuning (static or rotating, as applicable), set brake control timings, and verify torque‑proving before releasing loads. A quick load test at low speed helps catch setup issues early.
• Routine maintenance – Quarterly dust cleaning, fan check/replacement as needed, terminal re‑torque, and event log review. Firmware updates can be scheduled during downtime if recommended by the manufacturer.
• Safety – Implement STO wiring per dual‑channel guidance where required. Lockout/tagout and lift with chains rated for the equipment mass when servicing.
