FAQ
1. What type of servo motor is the Siemens 1FT7105-5AF71-1BG1?
The Siemens 1FT7105-5AF71-1BG1 is a SIMOTICS S 1FT7 permanent-magnet synchronous servo motor designed for industrial motion-control applications. It provides 8.8 kW of rated power at 3,000 rpm and is naturally cooled. The motor is suitable for demanding positioning, speed-control, and torque-control applications used with Siemens SINAMICS drive systems.
2. What are the rated speed and rated torque of the 1FT7105-5AF71-1BG1?
The motor has a rated speed of 3,000 rpm and a rated torque of 28.0 Nm. The static torque is 41.0 Nm at a 60 K temperature rise and 50.0 Nm at a 100 K temperature rise. For short-duration dynamic operation, the specified maximum torque reaches 200 Nm. The actual available torque depends on speed, drive configuration, duty cycle, load profile, and thermal operating conditions.
3. What type of encoder is used on the 1FT7105-5AF71-1BG1?
The 1FT7105-5AF71-1BG1 uses an AS24DQI absolute encoder with 24-bit single-turn resolution. It communicates with the SINAMICS drive through the DRIVE-CLiQ interface and provides absolute shaft-position feedback for closed-loop control. This configuration is suitable for precision positioning, coordinated motion, and multi-axis applications where accurate position feedback is required.
4. Does the Siemens 1FT7105-5AF71-1BG1 have a holding brake?
No. This configuration does not include an integrated holding brake. If the application requires the motor shaft to remain mechanically fixed after stopping or power loss, an external holding or braking system should be installed where required. For vertical or gravity-loaded axes, the external brake should be appropriately rated for the load and integrated with the machine’s safety and control functions.
5. What is the maximum permissible speed of the 1FT7105-5AF71-1BG1?
The maximum permissible mechanical speed is 6,000 rpm, while the maximum permissible inverter speed is 4,630 rpm. When operating the motor with the associated SINAMICS drive, the applicable inverter speed limit must be respected. The actual operating speed should also remain within the limits of the mechanical transmission, coupling, load, bearings, and complete machine.
6. What cooling method does the 1FT7105-5AF71-1BG1 use?
The motor uses natural cooling and does not require a separate forced-air cooling system in its standard configuration. Because this model has an 8.8 kW rated power, adequate heat dissipation is important during continuous operation. The installation should provide sufficient ventilation, while ambient temperature, duty cycle, load profile, and continuous torque demand should be considered when evaluating thermal performance.
7. What mounting configuration does the 1FT7105-5AF71-1BG1 use?
The motor uses IM B5 flange mounting and supports IM V1 and IM V3 mounting positions. It features a conventional flange design compatible with the 1FT6 mounting concept and uses a plain shaft for mechanical power transmission. The power connector is rotatable, which can simplify cable routing during installation. Accurate shaft alignment and secure flange mounting are important for reducing mechanical stress and vibration.
8. What should be checked when commissioning the Siemens 1FT7105-5AF71-1BG1?
Before commissioning, verify that the SINAMICS drive contains the correct motor data and encoder configuration. Check the power connections, protective grounding, DRIVE-CLiQ communication, encoder feedback, and Pt1000 temperature-sensor wiring. Perform an initial low-speed test to confirm rotation direction, position feedback, current response, acceleration, and deceleration. If encoder faults, abnormal current, positioning errors, excessive vibration, or unusual temperature occurs, stop operation and inspect the drive parameters, feedback connections, mechanical coupling, and load conditions before continuing.
