Analysis of Possible Scenarios

1. Non-standard Model: This model may be a project-specific customized product, a special batch product, or a regional product that is not included in Siemens’ standard product lineup.
2. Spare Part or Replacement Part: It may be a component or repair spare part of the servo motor brake system, rather than a complete product sold independently.
3. Model Nomenclature Discrepancy:

– Standard Siemens servo motor brakes are usually bound to the motor model instead of having independent part numbers.

– Standard naming example: 1FK7084-2AC71-1AA0 (with brake), distinguished by the suffix letters of the order number.

– Some brake components may adopt “Z + numbers” as option codes, z.B., “-ZF70” (with brake).

General Characteristics of Siemens Servo Motor Brake Systems

Funktionsprinzip

– Electromagnetic brake, released when energized and engaged when de-energized.

– Prevents unintended movement of the motor caused by gravity or external forces after power-off.

– Commonly used in applications with high safety requirements such as vertical axes and lifting mechanisms.

Typical Parameters

– Betriebsspannung: Normally 24V DC (±10 %)

– Operating Current: ≤0.6A

– Holding Torque: ≥12Nm (varies with motor specifications)

– Response Time: Adjustable via the drive parameter (p1216)

Verkabelungsmethode

V90 Series: The brake interface (X7) is integrated on the front panel of the drive.

Other Series: Connected to the drive via a dedicated connector.
