FFunctional Description

Release torque [33I]
The Brake Release Time [33C] sets the time the AC drive
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 level of release (holding)
torque. The set release torque is internally overruled 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 direction.
