Matching Selection & Replacement Instructions
- Recommended Matching Drives
Pulse control version: 6SL3210-5FB10-8UF0 (0.75 kW, 200 Classe V, Frame FSB)
PROFINET communication version: 6SL3210-5FE10-8UF0 (0.75 kW, 200 Classe V, Frame FSB)
Voltage and power ratings must be strictly matched. Mismatched combination will trigger drive alarms and even burn out motor windings.
- Sostituzione & Compatibilità
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 (per esempio. 1FL6044 series), due to incompatible shaft height, voltage and installation dimensions.
Applicazioni tipiche
Macchine per l'imballaggio: Film feeding, flying shear and fixed-length cutting stations for labelers, horizontal packaging machines and bag making machines
Movimentazione dei materiali: Small pick-and-place devices, linear modules and loading/unloading mechanisms for electronic components
3C assembly: High-precision positioning and high-speed reciprocating axes for screw drivers, dispensers and chip mounters

Difetti comuni & Troubleshooting Matrix
| Fenomeno di guasto | Causa ultima | Step-by-Step Solutions |
| Drive reports encoder fault (per esempio. F31110) | Loose encoder connector / oxidized pins; damaged cable; electromagnetic interference; defective encoder | 1. Spegnimento, 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 | Inceppamento meccanico; 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 | Circuito aperto / poor contact of power cables; drive enable signal disconnected; freno (opzionale) 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. |

Key Matching Instructions
- Corrispondenza dei parametri elettrici
Both drives accept 200~240 V AC input (monofase / three-phase applicable) with rated output current of 4.7 UN. It fully matches the motor rated current 2.6 A and peak current 7.8 UN, 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.
Note supplementari
Updated hardware models of the same power (per esempio. 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.
