Stop!
The control card will be damaged if
ƒ the voltage between X5/39 and PE or X6/7 and PE is greater than 50 V,
ƒ the voltage between voltage source and X6/7 exceeds 10 V (common mode)
in case of supply via external voltage source.
Limit the voltage before switching on the drive controller:
ƒ Connect X5/39, X6/2, X6/4 and X6/7 directly to PE or
ƒ use voltage−limiting components.
ƒ For trouble−free operation, the control cables must be shielded:
– Connect the shield of digital input and output cables at both ends.
– Connect the shield of analog input and output cables at one end (at the drive
controller).
– For lengths of 200 mm and more, use only shielded cables for analog and digital
inputs and outputs. Under 200 mm, unshielded but twisted cables may be used.
