In the case of a voltage dip on the mains, the voltage in the DC bus can be
reduced. This can cause the drive system to be cut off the mains when volt‐
age falls below certain levels and certain times are exceeded. When voltage
returns, the drive system has to be reactivated in order to continue operation.
Note on Project Planning "Over‐
voltage Limitation"
If connection to the supply mains is permanent and stationary in industrial en‐
vironment (subsequent to the main distribution board), there aren't any over‐
voltage limiters required up to an installation altitude of 2000 m (h
max_ohne
; see
chapter 5.3 "Installation Conditions" on page 58
). Installation altitudes of
more than 2000 m to a maximum of 4000 m require overvoltage limiters be‐
tween outer conductor and ground (recommended protection level: 2.5 kV).
Overvoltages at the devices can occur due to
●
inductive or capacitive coupling on lines
●
lightning strikes
Use overvoltage limiters at the machine or installation, when the
overvoltages at the devices are greater than the maximum al‐
lowed overvoltages.
Use the overvoltage limiters at long lines of the drive system run
through the building in parallel with power and mains cables.
Electrically place the overvoltage limiters as near as possible to
the point of entrance of the lines at the control cabinet.
