156 Program features
When the mechanical brake is closed and the drive stopped, that is, brake control is
active, the drive generates alarm BRAKE SLIP if the difference of the motor actual
speed and the speed reference is greater than the value of parameter
81.02 SPD
STD DEV LVL for a period longer than defined with parameter 81.04 SPEED MATCH
DLY.
The figure below illustrates the operation of the Speed match function.

Diagnostics
Parameters Additional information
81.01 SPEED MATCH Enables/disables the Speed match function.
81.02 SPD STD DEV LVL Defines the speed matching steady state deviation.
81.03 SPD RMP DEV LVL Defines the speed matching ramp state deviation.
81.04 SPEED MATCH DLY Defines the time delay for generating fault SPEED MATCH.
