Page 15: Installation
Installation Installation When installing into an enclosure ensure sufficient ventilation. The ambient temperature must not exceed +45 °C. Install the controller with the terminals at the top. External operating elements (e.g. switch, fuses) must not be arranged close (≤ 250 mm) to the controller 480. If this distance is not observed, a suitable cover must be provided in order to avoid accidental contact with the controller board. - Page 16 An electrical latching also prevents an automatic reconnection after the controller has cooled. The latching can only be eliminated by disconnection and reconnection of the mains! Notes for the connection of controller and motor Lenze controller Motor (acc. to DIN 42017 / VDE 0530 part 8) Function Termina...

Installation of the CE typical drive system The electromagnetic compatibility of a drive system depends on the type and accuracy of the installation. - Page 19 Assembly • Make the contact from controller, RFI filter, and mains chokes to the grounded mounting plate with as large a surface as possible. Zinc-coated mounting plates allow long-lasting contacts. For painted plates the paint of the mounting plates must be removed in all cases. •...

Page 26: Armature Voltage Control With "I X R Compensation
Armature voltage control with "I x R compensation" Caution! In this operating mode all control terminals carry mains potential. It is therefore necessary that all input and output signals required for the control of the controller are safely separated electrically by measures outside the controller and have another protection against direct contact (double basic insulation). -
Page 27: Speed Control With Tacho Feedback
Speed control with tacho feedback Caution! In this operating mode, the control electronics has a simple basic insulation. Take measures outside the controller to ensure that the input and output signals of the control have a double basic insulation. • Set set-value potentiometer or master voltage to zero. Connect mains. -
