The safety function pulse enable is active, if no voltage is applied to the input terminals

(X3-3/5). The pulses for IGBT control are inhibited.
24 V must be applied to the available terminals (X3-3/5), to deactivate the safety function.

The starting and the shutdown sequence of the release signals and of the safety relay must be
considered, in order to assure a faultless operation of the drive.

NOTE
The safety function must be checked, before commissioning the machine, in which
the BM4000, with the safety function STO is installed. For this purpose a protective
function must be enabled (for example door contact). The motor must be with zero-
torque.
