Siemens 1FL6042-2AF21-1AA1 Servo Motor

This is a low-inertia (높은 동적 성능) servo motor ~의 지멘스 SIMOTICS S-1FL6 series. It is specially matched with SINAMICS V90 series servo drives to form a cost-effective and high-dynamic servo system.

The motor features a rated power of 0.75 kW, rated torque of 2.39 N·m and rated speed of 3000 rpm. It is equipped with a built-in TTL incremental encoder (2500 pulses per revolution). The output shaft is designed with parallel key and without holding brake. Its protection class reaches IP65 (with standard shaft seal). With fast response, high acceleration and stable operation, it is ideal for various motion control applications requiring superior dynamic performance.

Matching Selection & Replacement Instructions

1. Recommended Matching Drives

Pulse control version: 6SL3210-5FB10-8UF0 (0.75 kW, 200 V 클래스, Frame FSB)

PROFINET communication version: 6SL3210-5FE10-8UF0 (0.75 kW, 200 V 클래스, Frame FSB)

Voltage and power ratings must be strictly matched. Mismatched combination will trigger drive alarms and even burn out motor windings.

2. 대사 & 호환성

Direct replacement with identical functions: 1FL6042-2AF21-1LA1 (only 90° elbow connector, identical electrical performance; applicable when installation space is limited)

Functional upgrade replacement: For position retention after power failure, select multi-turn absolute encoder model 1FL6042-2CF21-1AA1. The drive shall support absolute encoder protocol accordingly.

Prohibited replacement: Do not replace with high-inertia models of the same power (예를 들어. 1FL6044 series), due to incompatible shaft height, voltage and installation dimensions.

일반적인 응용 분야

포장 기계: 필름 공급, flying shear and fixed-length cutting stations for labelers, horizontal packaging machines and bag making machines

자재 취급: Small pick-and-place devices, linear modules and loading/unloading mechanisms for electronic components

3C 어셈블리: High-precision positioning and high-speed reciprocating axes for screw drivers, dispensers and chip mounters

Light industry equipment: Tension and position control for screen printers, small winding machines and indexing tables

일반 자동화: High-dynamic scenarios such as small manipulators, conveyor positioning and feeding of inspection stations

일반적인 결함 & Troubleshooting Matrix

Standard Models of Matched V90 Drives

The model 1FL6042-2AF21-1AA1 is a 200~240 V three-phase, 0.75 kW low-inertia incremental encoder servo motor. It is exclusively matched with SINAMICS V90 drives of the same voltage and power rating. Two official standard models with different control interfaces are available, which can be directly connected and automatically identify motor parameters.

Key Matching Instructions

1. 전기적 매개변수 매칭

Both drives accept 200~240 V AC input (단상 / three-phase applicable) with rated output current of 4.7 에이. It fully matches the motor rated current 2.6 A and peak current 7.8 에이, enabling the motor to operate at 3 times overload capacity.

2. Encoder Compatibility

Both drives natively support the motor’s TTL incremental encoder (2500 lines per revolution with zero signal). No additional encoder card is required. Motor nameplate parameters can be read automatically after power-on without manual input.

3. Selection Restrictions

Do not use 400 V class V90 drives (order number starting with `5FE`). Mismatched voltage will directly burn out motor windings.

It is not recommended to use drives with higher power rating. Although the motor can run, mismatched protection thresholds will lead to failure of overload protection and potential safety hazards.

보충 노트

Updated hardware models of the same power (예를 들어. suffix 8UA1, 8UF1) are only hardware revisions with identical functions and interfaces, which can be used as direct replacements. If the motor is later upgraded to absolute encoder type, no drive replacement is required; only parameter modification is needed.

Standad Order Numbers for Pre-assembled Cables

1FL6042-2AF21-1AA1 is a 200 V low-inertia servo motor with incremental encoder, no brake and straight connectors. Only power cables and encoder cables are required. Adopt Siemens MOTION-CONNECT 300 series pre-assembled cables, plug-and-play with IP65 protection class. The power cable is connected to drive via terminals, while the encoder cable uses dedicated connectors.

1. 전원 케이블 (4×2.5 mm², ~을 위한 200 다섯 0.75 kW low-inertia motor)

Motor-side straight connector, fully compatible with motor straight outlet interface.

2. Encoder Cables (for 2500-line incremental TTL encoder)

Matched with built-in incremental TTL encoder, with differential shielding.

3. Optional Brake Cable (Not required for this motor, for reference only)

If replaced with braked motor of the same frame (예를 들어. 1FL6042-2AF21-1AB1), an extra brake cable is needed.

선택 & 애플리케이션 노트

1. Connector Matching: The above cables are equipped with straight connectors on motor side, perfectly matching motors with suffix 1AA1. For motors with elbow connectors (suffix 1LA1), select cables with the second letter B (예를 들어. 6FX3002-5CK32-1BD0).
2. Length Limit: The maximum length of standard pre-assembled cables for 200 V low-inertia series is 20 중. 7 m and 15 m cables are only for 400 V high-inertia motors and not available for this series.
3. 설치 시나리오: MOTION-CONNECT 300 cables are designed for fixed installation. Not applicable for cable chains and continuous reciprocating motion. Select high-flexibility cables for dynamic operation.
4. 배선사양: Route power cables and encoder cables separately with a spacing of ≥20 cm. Implement reliable single-end grounding for shielding layer to avoid encoder signal loss or alarms caused by electromagnetic interference.
5. Custom Cable Solution: For on-site customized length, purchase separate motor-side connectors for crimping: Power connector: 6FX2003-0LL13; Incremental encoder connector: 6FX2003-0SL11.
