Matching Selection & Replacement Instructions
- Recommended Matching Drives
Pulse control version: 6SL3210-5FB10-8UF0 (0.75 кВт, 200 V class, Frame FSB)
PROFINET communication version: 6SL3210-5FE10-8UF0 (0.75 кВт, 200 V class, Frame FSB)
Voltage and power ratings must be strictly matched. Mismatched combination will trigger drive alarms and even burn out motor windings.
- Замена & Совместимость
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 (например. 1FL6044 series), due to incompatible shaft height, voltage and installation dimensions.

Распространенные неисправности & Troubleshooting Matrix
| Явление неисправности | Root Cause | Step-by-Step Solutions |
| Drive reports encoder fault (например. F31110) | Loose encoder connector / oxidized pins; damaged cable; electromagnetic interference; defective encoder | 1. Выключить питание, re-plug the motor-side encoder connector and check for retracted or oxidized pins. 2. Replace with a new shielded cable for testing. 3. Route encoder cables separately away from power cables and implement single-end grounding. 4. Replace the motor if hardware failure is confirmed. |
| Motor overload alarm and overheating housing | Механические помехи; excessive load inertia ratio; excessive loop gain; continuous operation under over-rated load | 1. Power off and rotate the shaft manually to eliminate mechanical sticking or excessive resistance. 2. The recommended load inertia ratio for low-inertia motors is ≤5:1. Install a reducer or switch to high-inertia model if over limit. 3. Properly reduce speed loop / position loop gain. 4. Optimize motion profile and lower continuous load rate. |
| Vibration and abnormal noise during operation | Improper control parameter tuning; loose coupling/flange; encoder signal interference; worn bearing | 1. Gradually reduce position loop gain to eliminate vibration. 2. Fasten mounting bolts and coupling set screws. 3. Check shielding and grounding of encoder cables. 4. If abnormal noise still exists during no-load running, inspect bearing lubrication and wear. |
| No torque output and motor fails to run after power-on | Открытая цепь / poor contact of power cables; drive enable signal disconnected; тормоз (необязательный) not released; defective drive power stage | 1. Measure voltage and continuity of three-phase power cables and fasten connectors. 2. Check enable signal from PLC and drive parameters. 3. For braked models, confirm normal 24 V power supply for brake. 4. Replace the drive to locate the faulty component. |
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
- Согласование электрических параметров
Both drives accept 200~240 V AC input (однофазный / three-phase applicable) with rated output current of 4.7 А. It fully matches the motor rated current 2.6 A and peak current 7.8 А, enabling the motor to operate at 3 times overload capacity.
- 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.
- 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.
Дополнительные примечания
Updated hardware models of the same power (например. 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.

Выбор & Application Notes
- 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 (например. 6FX3002-5CK32-1BD0).
- Length Limit: The maximum length of standard pre-assembled cables for 200 V low-inertia series is 20 м. 7 m and 15 m cables are only for 400 V high-inertia motors and not available for this series.
- Installation Scenario: 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.
- Спецификация проводки: 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.
- Custom Cable Solution: For on-site customized length, purchase separate motor-side connectors for crimping: Power connector: 6FX2003-0LL13; Incremental encoder connector: 6FX2003-0SL11.
