Setting tips
ƒ To avoid an early response in the case of forced ventilated motors, deactivate the
function, if necessary.
ƒ The current limits C0022 and C0023 only have an indirect effect on the I 2 t
calculation. However, you can prevent the motor from being actuated at the
maximum possible utilisation by the settings of C0022 and C0023.
)
Note!
If the controller is actuated at an increased rated power, the I 2 t monitoring can
respond if C0120 is set to a smaller value than 100 %.
2.4 Residual hazards of Lenze controllers
Protection of persons
ƒ According to their enclosure, Lenze controllers (frequency inverters, servo inverters,
DC speed controllers) and their components can carry a voltage, or parts of the
controllers can move or rotate during operation. Surfaces can be hot.
– If the required cover is removed, the controllers are used inappropriately or
installed or operated incorrectly, severe damage to persons or material assets can
occur.
– For more detailed information please see the documentation.
ƒ There is a high amount of energy within the controller. Therefore always wear
personal protective equipment (body protection, headgear, eye protection, ear
protection, hand guard) when working on the controller when it is live.
ƒ Before working on the controller, check if no voltage is applied to the power
terminals.
– the power terminals U, V, W, +UG, −UG, BR1 and BR2 still carry dangerous voltage
for at least 3 minutes after power−off.
– the power terminals L1, L2, L3; U, V, W, +UG, −UG, BR1 and BR2 carry dangerous
voltage when the motor is stopped.
– the relay outputs K11, K12, K14 can carry dangerous voltage when the drive
controller is disconnected from the mains.
ƒ The discharge current to PE potential is > 3.5 mA. In accordance with EN 61800−5−1
– a fixed installation is required.
– the design of the PE conductor has to be double or, in the case of a single design,
must have a cable cross−section of at least 10 mm 2 .
ƒ The controller can only be safely disconnected from the mains via a contactor on the
input side.
