Spring-applied brakes

Rated data
NOTICE
Engagement and disengagement times apply to rated voltage (± 0 %) and suppressor circuit of
the brakes with a varistor with DC switching. Without a suppressor circuit, the times may be
longer.
The currents are the maximum values when the brake is cold (value used for dimensioning the
current supply). The values for a motor at operating temperature are considerably lower.
Requirements with regard to the DC 24 V brake: smoothed DC voltage, ripple ≤ 1 %.
Maximum switching energy for each emergency stop with n= 3000 rpm for a maximum of 3-6
emergency stops per hour.
