Mechanical brake (actuation) for RASP5
The control of an external mechanical brake can be set for RASP5 with para-
meters P3-01 to P3-05.

P3-04 Brake M-Level
Release
Required motor torque level at which the
brake may be released.
Determines the torque in % of the rated
motor torque, which has to be present,
before the mechanical brake may be
released.
It is used to ensure that the motor is
connected and produces sufficient torque
to prevent the load dropping on release of
the mechanical brake.
Note:
This function is not active in V/Hz mode
(P6-01 = 6).

P3-05 Brake Release Delay Determines the time before the mecha-
nical brake is released.

￫ The frequency increases and releases the brake when the output frequency exceeds
the value set in P3-02.
Normal operation - drive is running
Stop order The frequency drops and the brake is applied when the output frequency falls below the
value set in P3-03.
￫ The drive continues the ramp to a standstill.
￫ The output of the drive is disabled.
