The standard installation position of the servo drives in the control
cabinet is the vertical installation position.
Servo drives with a built-in mains filter may exhibit a small leakage
current due to the capacitors in the filter. This fault current may
cause malfunctions of standard residual current circuit breakers.
Therefore, use so-called AC/DC-sensitive residual current circuit
breakers type B, in which DC current is also accounted for. Beckhoff
recommends residual current circuit breakers with switch-on delay.
A power failure can lead to the uncontrolled run-out of the drive
axes. Linear axes or lifting axes could then drive without braking
against the end stop. Via the uninterruptible power supply in the In-
dustrial PC, you have the possibility to buffer the supply voltage to
the control electronics until all axes are safely stopped.
