4.1 Important notes
Stop!
The drive controller contains electrostatically sensitive components.
The personnel must be free of electrostatic charge when carrying
out assembly and service operations.
Danger!
ƒ
The connection of all pluggable terminals has to be effected in a
deenergised state.
ƒ
Connecting and disconnecting the voltage supply (X2) due to the
charging processes of the DC bus capacitor may cause traces of
burning on the plug−in connection, and may result in a
destruction of the internal electronic circuit.
ƒ
A false polarity of the DC supply can bring about the destruction
of the drive. Before switching the drive on, ensure that the
polarity of the DC supply is correct.
Note!
For trouble−free operation, the following conditions are required:
ƒ
An installation according to EMC.
ƒ
The shield of the motor cable has to be connected to PE potential
as extensively as possible to prevent effects due to interference.
ƒ
The resolver cable, encoder cable, and the motor cable may have
a length of 10 m at a maximum!
ƒ
The feeding power supply units have to be sufficiently
dimensioned. The power supply units have to be protected
against overcurrent by means of appropriate input fuses.
