Siemens SIMOTICS M-1PH8 Configuration Manual

Lifetime operating energy W
max
MJ: Max. possible switching energy of the brake (for
emergency stop) until the brake linings have to be replaced, W
max
= W
E
x z
Number of emergency stops z: The speci󹪝ed number of emergency stops refers to the
speci󹪝ed conditions. A conversion can be made for operation under di󹪜erent conditions:
Number of EMERGENCY STOPs z = W
max
/W
E
Coil current A: Current to release the brake.
Opening time t
0
ms: Separating time until the brake opens (the speci󹪝ed values refer to the
maximum braking torque and at rated voltage).
Closing time t
C1
ms: Interlocking time until the brake closes according to diagram
"Terminology (time) for holding operation." (the values refer to the maximum braking torque
and at rated voltage.).
Use for the intended purpose
"Single-disk spring-operated brake control modules" are for mounting on induction or
synchronous motors and intended for use in commercial or industrial systems. Use in hazardous
areas is absolutely prohibited. The integrated single-disk spring-operated brake
(electromagnetically opening system) is designed as holding brake. Occasional Emergency Stop
operations are possible.
NOTICE
Irreversible reduction of the braking e󹪜ect
The braking e󹪜ect can be irreversibly reduced if you do not comply with the permissible number
of braking operations per hour and/or the maximum permissible operating energy per hour.
Further, this can have a negative impact on the function of the holding brake.
• When setting up machines and systems (when using the jog mode), carefully observe the
information provided in the Table "Technical data of holding brakes".
• You can equip the holding brake with a manual brake release to remove the holding torque.
NOTICE
Inadvertent operation of the holding brake
Material damage can occur if you inadvertently apply or release the holding brake.
• Secure the holding brake against inadvertent operation and misuse. The mechanical
manual brake release must be in the center position when not actuated (see the diagram
“Spring-actuated single-disk brake module"). Only then is the brake completely closed, and
it is ensured that the spring-actuated single-disk brake module can provide its full braking
e󹪜ect.
• You can remove the manual release lever. Strictly observe the speci󹪝c system-related
regulations, e.g. in the crane construction area relating to whether manual brake release is
permissible.
• For the rated operating conditions, see DINVDE0580:1994-10. For the degree of
protection see DIN VDE 0470, part 1. If deviations exist, coordinate special measures with
the manufacturer.
