Engagement time
For closing (equivalent to the disengagement time for opening), the brake requires an
application time. In the engagement time, the full holding torque is positioned on the
drive, so that the position reached is also maintained during the closing process of the
brake. A minimum engagement time of 150 ms is recommended. This time is
system-dependent.
5.4 System menu
On this menu page, system units, such as conversion factors and display units, direction of
rotation of the motor shaft with regard to the setpoint of the direction of rotation and to
the limit switch are entered. Furthermore, the offset after the reference run and the type
of evaluation of the motion, i. e. a linear axis or a rotary axis, can be specified on this menu
page.

5.4.1 Conversion
Depending on whether a linear axis or a rotary axis is used, here the ratio of the primary
motion (in motor revolutions, gearbox revolutions, or resolver increments) to the
secondary motion on the rotary axis (in revolutions, on the linear axis in m, dm, cm, mm,
mm) is specified. If the unit ”increments” is used, it has to be observed that 4096
increments correspond to one motor revolution or to 360°.
