8.4.2.3 Switching thresholds
Upper speed threshold for brake release:
Switching threshold (
C02581/1 ) + hysteresis for release ( C02581/2 )
Lower speed threshold for brake application:
Switching threshold (
C02581/1 ) - hysteresis for application ( C02581/3 )

Tip!
The lower speed threshold for brake application should be set to approximately 5 ... 20 % of
the maximum speed to minimise the wear of the brake and provide for an optimum brake
reaction by a low grinding of the brake.


Stop!
Do not set the lower speed threshold for closing the brake too high to prevent excessive
wear of the brake!

Note!
When comparing speeds, only the absolute value of the motor speed and not the
direction of rotation is considered.
