5.2.5 Holding brake (option)
5.2.5.1 Properties
Operation with holding brake on the SINAMICS S
The SINAMICS S drive system has various types of brake control. A detailed description of the
individual functions and corresponding parameter assignment information is provided in the
following manuals:
• SINAMICS S120 Function Manual (6SL3097-4AB00-0AP1)
• SINAMICS S120/S150 List Manual (6SL3097-4AP00-0AP3)
Information on the current carrying capacity of the brake outputs/adapters of the individual
SINAMICS power units can be found in the corresponding manuals. It may be necessary to
control the brake using additional switching elements.
Ensure that the brake data are correctly parameterized in SINAMICS. This is particularly
important for the setting values:
• Maximum motor speed (reduced value for the "holding brake" option)
• Opening and closing times of the holding brake
• Moment of inertia of the holding brake
The corresponding setting values are listed for the specic brakes in the "Technical data of the
holding brake" table.
Functional principle of the holding brake
A brake can be mounted at the DE side of 1PH8 motors, shaft heights 80, 100, 132, 160, 180 and
225.
These brakes are electromagnetic units for dry-running operation. An electromagnetic eld
is used to release the brake which is applied using spring force. They function according to
the closed-circuit principle, i.e. when in a no-current state, the spring-actuated brake closes
and holds the drive. When power is applied to the brake, it is released and the drive is free to
rotate.
In the event of a power failure or an Emergency Stop, the drive is braked from its actual
speed down to standstill.
