Make sure the parameter assignments for the brake data in the SINAMICS are correct. This
is particularly important for the setting values:
●
Maximum motor speed (reduced value for the "holding brake" option)
●
Release and engaging times of the holding brake
●
Moment of inertia of the holding brake
The corresponding setting values are listed for the specific brakes in the "Technical data of
the holding brake" table.
Functional principle of the holding brake
A brake can be mounted at the drive end of 1PH8 motors, shaft heights 80 and 100.
These brakes are electromagnetic units for dry-running operation. An electromagnetic field is
used to release the brake which is applied using spring force. They function according to the
closed-circuit principle, i.e. the spring-applied brake is triggered when the current is
interrupted and holds the drive. When power is applied to the brake, it is released and the
drive is free to rotate.
When the power fails or an emergency stop is issued, the drive is braked from its actual
speed down to standstill.
Connection of the brakes (must be provided by the customer)
●
Alternating voltage 230 V AC, 50 ... 60 Hz
●
DC voltage of 24 V DC
Ambient temperature
The brake module is designed for an ambient temperature of -5 °C to +40 °C. At
temperatures below -5 °C and longer periods without power being applied to the brake, then
it cannot be excluded that the friction disk freezes. In this case, special measures must be
applied after first contacting the manufacturer.
Note
Restricted maximum motor speed for a motor equipped with brake
The maximum speed of a motor with brake is limited to the maximum speed of the brake
(see n
max, Br
speed specified in the characteristic curves).
Note
Selection and ordering data
The selection and ordering data can be found in the Configuration Manual "SIMOTICS M-
1PH8 main motors", Chapter "Selection and ordering data".
Holding brakes in the 24 V DC version are UL-approved. Please consult your Siemens
regional office for further information about holding brakes in the 230 V AC version.
