Siemens 6BK1136-6AB01-0CU0 SIMATIC ET 200SP F-TM ServoDrive HF 5A 24-48V DC Servo Drive

The Siemens 6BK1136-6AB01-0CU0 is the F-TM ServoDrive HF drive controller module for the SIMATIC ET 200SP distributed I/O system, designed for servo and stepper motors operating in safety low-voltage environments. It accepts a 24 to 48 V DC bus (16.8–57.6 V range), delivers a 5 A rated output with a 15 A peak, and integrates hardwired STO (Safe Torque Off) for functional-safety applications without an additional safety relay.

Selection Notes

The 5 A rated current (15 A instantaneous peak) targets small-frame servo and stepper motors in the sub-300 W range — typical candidates include SIMOTICS S-1FK2 and compact stepper actuators powered from a 24 V or 48 V PELV bus. The 3:1 peak-to-rated ratio supports short-duration acceleration torque without thermal derating at steady state. Hardwired STO (antivalent dual-channel 24 V DC) satisfies functional-safety stop-category requirements without an external safety relay, reducing panel footprint compared to a standard TM ServoDrive paired with an F-DQ relay. The BiSS-C encoder interface enables single-cable absolute-position feedback at 599 Hz output frequency, sufficient for most positioning axes in the ET 200SP backplane. If the application demands higher continuous torque (above 5 A RMS) or ground-fault monitoring, step up to a higher-rated ServoDrive variant; if STO is to be handled via PROFIsafe over the backplane rather than hardwired, the non-HF F-TM ServoDrive is the correct selection.
