Process and Application Parameters [300]
Section 11-3
Brake Fault trip time [33H]
Communication information
Note
The Brake Fault trip time should be set to longer time than the Brake release
time[33C].
The “Brake not engaged” warning is using the setting of parameter “Brake
Engaged time [33E]”.
Following Figure shows principle of brake operation for fault during run (left)
and during stop (right)
Release torque [33I]
The brake release time [33C] sets the time the VSD delays before ramping up
to whatever final speed reference value is selected, to allow the brake to be
fully opened. During this time a holding torque to prevent roll-back of the load
can be activated. The parameter release torque [33I] is used for this purpose.
The release torque initiates the torque reference from the speed controller
during the Brake Release Time [33C]. The release torque defines a minimum
torque of release (holding) torque. The set release torque is internally overrul-
led if the actual required holding torque measured at the previous closing of
brake is higher.
The release torque is set with sign in order to define the holding torque direc-
tion.
