Schneider ELAU SM140-30-370-P1-45-S1-B0 Servo Motor

Core Features

• ✓ Plug-and-Play Legacy Upgrades:  Designed with a standard IMB 5 conventional flange, this motor is physically identical to earlier 1FT6 and 1FK7 generations, allowing you to instantly modernize your machinery without costly mechanical redesigns.
• ✓ Zero-Homing Startups (24-Bit Encoder): Features a state-of-the-art AS24DQI single-turn absolute encoder. By communicating natively via DRIVE-CLiQ, the drive instantly knows its exact rotational position upon power-up, bypassing tedious homing routines.
• ✓ Failsafe Load Suspension: Integrates a heavy-duty holding brake directly onto the plain shaft. This critical safety mechanism automatically engages during power losses, firmly locking vertical axes or suspended weights in place to prevent equipment damage.
• ✓ Rugged, Fanless Architecture (IP65): Delivers 5.65 kW of continuous power silently through optimized natural convection cooling. Paired with a strict IP65 protection rating, it thrives in environments exposed to heavy dust and multi-directional water spray.

Q: How does the encoder handle position memory after a power cycle?

A: Because it utilizes a 24-bit absolute encoder (AS24DQI), it permanently tracks its mechanical position. When power is restored to the SINAMICS S120 drive system, the exact axis location is immediately recognized via the DRIVE-CLiQ network, eliminating the need for reference point approaches.

Q: Is the 1FT7086-1AF71-1BH1 difficult to retrofit into older machines?

A: Not at all. It is specifically built with a conventional flange that shares the identical mounting footprint of legacy SIMOTICS 1FT6 and 1FK7 motors. You get all the benefits of next-gen performance as a simple, direct drop-in replacement.

Q: Can this motor be used safely on vertical or gravity-loaded axes?

A: Yes, absolutely. The internal holding brake is normally engaged and releases only when power is applied. If an emergency stop occurs or power fails, the brake instantly clamps the plain shaft, safely suspending heavy loads and protecting your machine from catastrophic drops.
