All Control Modes of ABB ACS580-01-246A-4

All ACS580 drives share one unified control core with no functional cuts for the 246 A (R8 frame) model. Three major control categories are supported: Scalar V/F, Sensorless Vector, Vector with Encoder, subdivided into 5 operation modes to cover fans/pumps, general heavy loads and high-precision positioning applications.

99. Scalar V/F Control (Parameter 99.04 = SCALAR)
100. Linear V/F (Default for Light Load Fans & Pumps)

Voltage rises linearly with frequency with uniform voltage boost from 0~50 Hz. Suitable for fans, blowers, pumps and general centrifugal loads.

Features: Simple structure, multi-motor parallel drive (one VFD driving multiple asynchronous motors); weak low-speed torque, zero torque at 0 Hz.

Applications: HVAC systems, constant-pressure water supply, multi-pump parallel systems.

2. Quadratic V/F (Square Curve, Dedicated for Fans & Pumps)

Voltage increases proportional to the square of frequency, matching the torque characteristic of fans and pumps for optimal energy efficiency.

Features: Greatly reduces motor excitation loss and reactive power under light load; even weaker low-speed torque.

Typical scenarios: Cooling tower fans, circulation pumps, dust extraction blowers.

3. Boostable Torque V/F (Voltage Boost V/F)

Raises output voltage at low frequencies to compensate insufficient low-speed torque.

Applications: Belt conveyors, mixing equipment, light starting resistance loads.

99. Sensorless Flux Vector Control (Parameter 99.04 = SENSORLESS)

The primary general heavy-load control of ACS580; no encoder required, standard for this 246 A model with no extra options needed.

Core Performance

2. Torque response ＜10 ms, far superior dynamic speed regulation over V/F control
3. Supports precise current limiting, anti-stall protection and continuous heavy-load operation
4. Static & rotating motor identification supported, compatible with new and old motors

Applicable Loads

Conveyors, mixers, extruders, compressors, woodworking machinery, single heavy-duty motor drives.

Limitations

Cannot maintain full torque at zero speed (0 Hz); precise closed-loop speed control unavailable without encoder feedback.

III. Vector Control with Encoder (Parameter 99.04 = ENCODER)

Requires optional FEN-01 / FEN-11 encoder interface module installed in the VFD expansion slot.

1. Supports pulse encoders: HTL / TTL incremental encoders
2. Closed-loop speed control with 100% continuous rated torque at 0 Hz
3. Speed control accuracy ±0.01% of rated speed
4. Enables simple positioning, jog operation and tension control

Applications

1. Two Operation Reference Modes (Speed Command Source, Independent of Above Motor Control Algorithms)
2. Local Control (Panel Reference)

Frequency set via control panel knob / buttons; local start-stop and speed adjustment for single-unit commissioning.

2. Remote Control (External Reference, Mainstream for Engineering)

Speed commands and start-stop signals come from external channels with flexible combinations:

1. Analog reference: AI1/AI2 (0–10 V / 4–20 mA)
2. Multi-speed DI digital terminal reference: Up to 7 fixed preset speeds
3. Pulse frequency reference (optional IO module required)
4. Fieldbus reference: Modbus RTU (standard), Profibus DP, Profinet, EtherNet/IP, etc.

6. Special Process Control Modes (Built-in Functions Based on Vector / V/F Core)
7. PID Process Control

Independent onboard PID regulator; no external PLC required for automatic constant pressure and flow control of pressure, liquid level and temperature.

2. Multi-pump Cycling Soft Start (HVAC Special Function)

Applicable Scenarios of Closed-Loop Vector Control with Encoder for ABB ACS580-01-246A-4

Preface

This control mode uses parameter code 99.04=ENCODER. Optional FEN-01 (HTL) / FEN-11 (TTL) incremental encoder modules are mandatory. Real-time speed feedback from the motor shaft encoder delivers three core advantages:

1. Continuous 100% rated torque holding at 0 Hz (sensorless vector cannot hold load at zero speed)
2. Speed control accuracy ±0.01% rated speed with no low-speed jitter or step loss
3. Supports precise tension closed-loop control, multi-axis synchronization, simple positioning and constant-torque processes

Closed-loop vector control is only selected for working conditions requiring zero-speed load holding, high low-speed precision, stable tension, multi-axis synchronization and slip-free heavy start-stop. Standard fans, pumps and single ordinary conveyors can operate reliably with sensorless vector or V/F control only.

1. Winding & Unwinding Industry (Most Typical High-power Application, Matching 132 kW Class 246 A Model)

Applicable Equipment

Paper rewinders, plastic film extrusion winders, rubber calender winding/unwinding machines, non-woven slitting machines, metal foil wire drawing & winding machines, cable stranding machines

Mandatory Process Requirements for Closed-Loop Vector

1. Smooth low-speed startup and constant tension maintenance during shutdown; no loose rolls, stretching or material breakage at zero speed
2. Automatic constant tension as roll diameter dynamically changes between large and small reels, speed follows upstream master machine
3. No tension fluctuation during high-low speed switching to prevent wrinkling or stretching deformation of web materials
4. Multi-section linkage: Synchronized operation of unwinding-traction-winding three axes

Open-loop Disadvantages: Insufficient low-speed torque without encoder leads to web slipping and out-of-control tension.

1. High-precision Positioning / Intermittent Reciprocating Heavy-duty Equipment

Applicable Equipment

Large gantry feeders, heavy plate translation positioning tables, stone cutting feeders, cement block stacking conveyors, large packaging reciprocating cross-cutting machines

Process Requirements

1. Precise stop at target positions with minimal repetitive positioning error; frequent jog & inching maintenance operations
2. No position shifting or slipping when stationary under full load
3. No speed overshoot during acceleration & deceleration; no jitter or impact on heavy start-stop

III. High-inertia Overhauling / Vertical Lifting Constant-torque Loads (High-power 110/132 kW Heavy-duty Conditions)

Applicable Equipment

Downward mine belt conveyors, large bucket elevators, heavy vertical mixers, lifting silo discharge drives

Process Pain Points Unsolvable by Open-loop Control

Reverse load generated by material self-weight requires full torque braking maintained at zero shutdown speed; overhaul runaway and overvoltage alarms easily occur at low descending speeds. Encoder closed-loop corrects speed in real time to suppress regenerative impact and stabilize DC bus voltage with braking units.

1. Multi-motor Synchronized Production Lines (Long-distance High-power Synchronous Transmission)

Applicable Equipment

Cement kiln chain conveyors, long-distance multi-drive mine belts, multi-layer drying synchronized roller tables, continuous metal pickling lines

Process Requirements

Rigid synchronization of multiple motors with minimal speed deviation across sections to avoid plate stretching, belt deviation and tearing. Closed-loop vector with encoder feedback achieves far superior multi-motor synchronization accuracy compared to open-loop sensorless vector.

1. Heavy-duty Equipment for Extrusion, Kneading & High-viscosity Mixing

Applicable Equipment

Plastic single/twin-screw extruders, rubber internal mixers, chemical high-viscosity reactor agitators, main asphalt mixing machines

Process Requirements

1. Extremely high starting resistance for low-temperature high-viscosity materials; full torque output at 0 Hz to avoid startup stalling
2. Constant extrusion torque throughout operation for uniform output thickness
3. No torque ripple under steady low-speed operation for consistent product thickness
4. Centrifuges & High-speed Precision Rotating Equipment

Applicable Equipment

Large chemical separation centrifuges, high-speed paper dehydration centrifuges, large horizontal food centrifuges

Process Requirements

High-precision stable speed across wide speed ranges with minimal speed fluctuation during acceleration/deceleration. Real-time speed correction via encoder feedback at high operating speeds eliminates resonance and uneven material stratification.

VII. High-power Stenter, Setting & Padder Equipment for Textile Printing & Dyeing

Applicable Equipment

High-power stenters, water squeezing & calendering machines, continuous dyeing long lines

Process Requirements

Synchronized drafting of multiple rollers without fabric stretching or shrinkage; zero-speed load holding during low-speed fabric threading to avoid fabric accumulation and slipping; stable tension throughout operation.

VIII. Scenarios Unsuitable for Closed-Loop Vector Control (Select V/F or Sensorless Vector Directly)

1. Fans, cooling towers, circulation pumps, dust extraction blowers (variable-torque loads with no zero-speed load holding demand)
2. Single light-duty belt conveyors, small mixers, compressors (no high-precision synchronization or tension control requirements)
3. One-drive-multiple parallel multi-motor systems (only scalar V/F control applicable; encoder closed-loop cannot support multi-motor parallel driving)
