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!
The following requirements have to be met with regard to the trouble−free
operation:
ƒ
An installation according to EMC.
ƒ
The shield of the motor cable has to be applied to PE potential on a
preferably large surface in order to prevent negative effects.
ƒ
The resolver cable, encoder cable, and the motor cable may have a
maximum length of 15 m!
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.
