FAQ
1. What type of servo motor is the Siemens 1FK7100-2AF71-1RG1?
The Siemens 1FK7100-2AF71-1RG1 is a SIMOTICS S 1FK7 Compact permanent-magnet synchronous servo motor. It is designed for industrial motion-control applications that require controlled speed, accurate positioning and stable torque performance. The motor uses natural cooling and an absolute encoder with DRIVE-CLiQ communication.
2. What are the rated power and rated speed of the 1FK7100-2AF71-1RG1?
The motor has a rated power of 3.8 kW and a rated speed of 3000 rpm. The optimum operating speed is also 3000 rpm. The maximum permissible mechanical speed and maximum inverter speed are both 5000 rpm. The actual operating speed should be selected according to the machine load and motion profile.
3. What is the rated torque of the Siemens 1FK7100-2AF71-1RG1?
The rated torque is 12.0 Nm at a 100 K temperature rise. The static torque is 14.90 Nm at 60 K and 18.00 Nm at 100 K. The maximum torque is 55 Nm under the specified operating conditions. Continuous torque must be selected according to the motor’s thermal characteristics and the drive operating limits.
4. What encoder is installed on the 1FK7100-2AF71-1RG1?
The motor uses an AM20DQI absolute encoder with 20-bit single-turn resolution and 12-bit multi-turn information. The encoder provides 1,048,576 resolution counts and supports a multi-turn range of 4096 revolutions. The DRIVE-CLiQ interface allows the encoder information to be transferred directly to a compatible Siemens drive for closed-loop motion control.
5. Does the Siemens 1FK7100-2AF71-1RG1 have a holding brake?
No. The standard 1FK7100-2AF71-1RG1 configuration is supplied without a holding brake. If the machine requires the motor shaft to remain mechanically secured after the servo drive is disabled, an external holding mechanism or a suitable motor variant with an integrated brake should be considered.
6. What cooling method does the 1FK7100-2AF71-1RG1 use?
The motor uses natural cooling. No separate external fan or liquid-cooling system is required for normal operation. Proper heat dissipation remains important, particularly when the motor operates continuously at high torque or is installed in an enclosed machine structure.
7. Which mounting positions are supported by this Siemens servo motor?
The 1FK7100-2AF71-1RG1 supports IM B5 mounting and can also be installed in IM V1 and IM V3 positions. The mounting flange should be securely fixed, and the motor shaft should be correctly aligned with the driven mechanism. Proper alignment helps reduce vibration, bearing loads and mechanical stress during operation.
8. What should be checked when commissioning the 1FK7100-2AF71-1RG1?
Before commissioning, verify the motor order number, compatible Siemens drive, power connections, grounding, mechanical coupling and DRIVE-CLiQ encoder connection. Confirm that the AM20DQI encoder is correctly detected by the drive and verify the motor rotation direction at low speed. The operating speed and load can then be increased gradually while monitoring current, torque, vibration and motor temperature.
