Setting 1: Match Frequency Reference and Motor Speed
Note: In V/f control the drive ignores the value set to L4-08 and refers to the soft-starter output to determine whether a speed agreement
situation has been reached.
The following functions are influenced by the speed agree condition:
• Overtorque alarms oL3 and oL4 when parameters L6-01 or L6-04 are set to 1, 3, 5, or 7.
• DriveWorksEZ functions that use speed agree output
• The Up 2/Down 2 functions
• Multi-Function Digital Output Settings

Notes on Controlling the Brake for the Hoist Application
The frequency detection function is used for controlling the brake.
When
an external Baseblock command is present while
a Run command is active, the frequency reference will be kept as
long as the Run command is active. To avoid improper brake operation make sure that frequency detection is set so that
the brake does not open during Baseblock (L4-07 = “0”, default).

The braking sequence should be designed as follows:
• A normally open signal (N.O.) should be used to control the brake so that it is released when terminal MA-MC closes.
