01
Product Identification
1FT7084-5AH71-1BG0 is a SIMOTICS S-1FT7 permanent-magnet synchronous compact motor with shaft height 80 and natural cooling. Its rated speed is 4,500 rpm, with a rated torque of 9.5 Nm and rated current of 7.80 A under the 100 K operating data.
The motor uses an AS24DQI 24-bit absolute singleturn encoder with DRIVE-CLiQ and RJ45 connection. It has a plain shaft, Pt1000 temperature monitoring, IP64 protection and an IM B5 flange arrangement compatible with the documented 1FT6 mounting context.

Functions
- Delivers dynamic synchronous servo motion with a compact permanent-magnet rotor design.
- Provides 4,500 rpm rated operation and an 8,000 rpm mechanical maximum for suitable motion profiles.
- Returns 24-bit absolute singleturn position data through the DRIVE-CLiQ encoder interface.
- Uses Pt1000 monitoring to report winding temperature to the drive system.
- Supports natural cooling without a separately powered fan.
- Interfaces to a selected SINAMICS motor module sized for the motor current and motion duty.
04
Applications
- High-dynamic machine axes requiring precise speed and position control.
- Packaging, handling and production machinery using SINAMICS DRIVE-CLiQ feedback.
- Compact servo installations that can dissipate motor heat by natural cooling.
- Axis replacement where the IM B5 flange, shaft, encoder and connector orientation match.
- Motion systems whose load profile remains within the rated and maximum torque-speed envelope.
05
Lifecycle
- Match the complete 1FT7084-5AH71-1BG0 order number because winding, encoder, shaft and connector options are encoded in the MLFB.
- Retain the motor nameplate, drive parameters, encoder configuration and mechanical coupling data before exchange.
- Verify the 18 A recommended motor-module rating against the installed SINAMICS hardware and duty cycle.
- Check flange dimensions, shaft fit, cable interfaces, connector orientation and IP64 sealing during installation.
- Complete motor identification, encoder alignment and controlled axis tuning before returning the machine to production.
