The 1FK7063-5AF71-1EG0 is a 1FK7 Compact permanent-magnet synchronous servo motor designed for closed-loop positioning, speed regulation and cyclic industrial motion.
It provides 11 Nm of static torque, 7.3 Nm of rated torque and a rated speed of 3000 rpm. Its rated output is approximately 2.29 kW.
The defining feature of this EG0 configuration is its EnDat absolute encoder with 2048 positions per revolution.
Unlike newer DRIVE-CLiQ encoder versions, this motor uses a conventional EnDat feedback interface. It is therefore particularly relevant for machines originally designed around an EnDat-compatible drive or encoder-evaluation system.
The motor is supplied with a plain shaft, natural cooling and no integrated holding brake. Its IP64 housing is suited to enclosed industrial machinery where dust resistance and protection against splashing water are required.
This model should not be presented as a universal replacement for all 1FK7063 motors. The encoder interface, shaft configuration, brake option and protection class must match the original machine.

11 Nm Compact Torque Class
The 1FK7063-5AF71-1EG0 belongs to the 11 Nm static-torque class.
Typical applications include:
- Medium-size positioning axes
- Gearbox input drives
- Conveyor sections

Rated and Static Torque
Static Torque
11 Nm at 100 K
Rated Torque
7.3 Nm at 100 K
Recommended Operating-Point Maximum Torque
24.5 Nm
The static-torque value describes operation at standstill under specified thermal conditions.
The rated-torque value describes continuous operation at the rated speed.
The maximum-torque value is available only within the approved current, thermal and drive limits.
3000 rpm Speed Configuration
The AF71 winding is configured for a rated speed of 3000 rpm.
This operating point provides a balance between:
- Continuous torque
- Dynamic acceleration
- Machine-cycle speed
- Gearbox compatibility
- Thermal loading
- Positioning response
It should be distinguished from higher-speed 1FK7063 winding versions.
EnDat Absolute Encoder
The motor uses an EnDat absolute encoder with 2048 positions per revolution.
The encoder supplies:
- Absolute rotor-position feedback
- Speed information
- Motor commutation data
- Direction information
- Closed-loop position feedback
The EnDat interface transfers digital position information between the encoder and compatible drive electronics.
A-2048 Encoder Configuration
The encoder designation for this configuration is A-2048.
Its principal characteristics are:
- Absolute position measurement
- 2048 positions per revolution
- EnDat communication
- Dedicated signal connector
- Compatibility with approved encoder-evaluation hardware
It should not be described as a DRIVE-CLiQ encoder.
EnDat vs DRIVE-CLiQ Feedback
EnDat A-2048
Uses a dedicated EnDat feedback interface.
Requires compatible encoder-evaluation hardware.
Commonly found in earlier drive and machine generations.
DRIVE-CLiQ Encoder
Uses digital DRIVE-CLiQ communication.
Supports electronic motor identification and direct system integration.
Used in later motor configurations.
These encoder systems are not automatically interchangeable.
Encoder-Related Performance Reduction
Official product descriptions state that the motor performance is reduced by approximately 10 percent due to the selected absolute encoder configuration.
This means motor sizing should be based on the official data for this exact order number rather than on a mechanically similar 1FK7063 motor with a different encoder.
Do not copy torque or current values from incremental-encoder or DRIVE-CLiQ variants.
Plain Shaft Configuration
The motor is supplied with a plain shaft.
It is suitable for:
- Clamping couplings
- Bellows couplings
- Shrink-disc connections
- Low-backlash gearbox inputs
- Direct-coupled machine loads
A plain shaft should not be replaced with a keyed-shaft motor without checking the coupling design.
No Integrated Holding Brake
The 1FK7063-5AF71-1EG0 does not include a holding brake.
This configuration is suited to:
- Horizontal axes
- Mechanically self-locking systems
- Axes with an external brake
- Loads that do not require shaft holding after shutdown
Vertical or suspended loads require a separate validated holding arrangement.
IP64 Protection
The motor has an IP64 protection rating.
IP64 provides protection against:
- Dust ingress
- Splashing water from different directions
It does not mean the motor is suitable for:
- Direct high-pressure water jets
- Continuous washdown
- Immersion
- Outdoor exposure without further protection
The final protection level depends on correct connectors, cables and shaft sealing.
Natural Cooling
The motor dissipates heat through its housing and mounting flange without an external fan.
Reliable operation requires:
- Firm flange mounting
- Adequate heat transfer
- Unobstructed airflow
- Correct ambient conditions
- Approved motor parameters
- Operation within the torque-speed curve
The term naturally cooled is more accurate than self-cooling efficiency.
Rotatable Connectors
The power and signal connectors can be rotated to support different cable-routing directions.
This helps with:
- Compact cabinet and machine layouts
- Reduced cable bending
- Easier installation
- Improved connector access
- Cleaner motor-cable routing
Connector rotation limits should be observed during installation.
Motor and Drive Integration
A complete operating axis normally includes:
- Compatible Control Unit
- Compatible Motor Module
- Line or power-supply module
- Motor power cable
- EnDat feedback cable
- 1FK7063-5AF71-1EG0 motor
- Mechanical coupling or gearbox
- Approved motor and encoder parameters
The 600 V DC value refers to the associated drive-system DC link. The motor must not be connected directly to a 600 V DC source.
