Brake-Release Torque Reference
Program  Crane/Hoist  Closed Loop Hoist Control
This parameter sets the output torque level threshold that must be reached
within the time setting of the
initiate the Brake Release during normal operation.
This setting is also used as a reference during the count-down of the
Release Torque Stable Time.
See Figure 32 on pg. 235 for additional information on this parameter.
Brake-Release Torque (Proving) Time
Program  Crane/Hoist  Closed Loop Hoist Control
The output-torque level requirement for the brake-release function must be met
before the brake can release.
This parameter is used to set a time in which the
Reference (F988) criteria must be achieved.
See Figure 32 on pg. 235 for additional information on this parameter.
Brake-Release Torque Stable Time
Program  Crane/Hoist  Closed Loop Hoist Control
Once the brake signal is initiated this parameter sets the time that the output
torque level must remain at or above the torque level set at
brake is released.
See Figure 32 on pg. 235 for additional information on this parameter.
Brake-Release Mechanical (Delay) Time
Program  Crane/Hoist  Closed Loop Hoist Control
This parameter sets the time for completing the
(F992).
See Figure 32 on pg. 235 for additional information on this parameter.
Brake-Set Mechanical (Delay) Time
Program  Crane/Hoist  Closed Loop Hoist Control
Once the brake signal is initiated this parameter sets the time that must elapse
before the brake engages.
See Figure 32 on pg. 235 for additional information on this parameter.
