Installation and other work may only be carried out by qualified electricians and with the device disconnected. The operating instructions must always be available to these persons and must be strictly observed.
SK 180E Manual for frequency inverters CAUTION The heat sink and all other metal components can heat up to temperatures above 70°C. When mounting, sufficient distance from neighboring components must be maintained. When working on the components, allow sufficient cooling time beforehand Protection against accidental contact may need to be provided. ATTENTION The power unit can continue to carry voltages for up to 5 minutes after being switched off at the mains.

9 Additional Information 9.2 Process controller The process controller is a PI controller which can be used to limit the controller output. In addition, the output is scaled as a percentage of a master setpoint. This provides the option of controlling any downstream drives with the master setpoint and readjusting using the PI controller.

9 Additional Information 9.3 Electromagnetic compatibility (EMC) 9.3.1 General Provisions As of July 2007, all electrical equipment which has an intrinsic, independent function and which is sold as an individual unit for end users, must comply with Directive 2004/108/EEC (formerly Directive EEC/89/336). There are three different ways for manufacturers to display compliance with this directive: 1.

9 Additional Information 9.4 Reduced output power The frequency inverter is designed for certain overload situations. For example, 1.5x overcurrent can be used for 60 sec. For approx. 3.5 sec a 2x overcurrent is possible.
SK 180E Manual for frequency inverters 9.4.2 Reduced overcurrent due to time The possible overload capacity changes depending on the duration of an overload. Several values are cited in this table. If one of these limiting values is reached, the frequency inverter must have sufficient time (with low utilisation or without load) in order to regenerate itself. If operated repeatedly in the overload region at short intervals, the limiting values stated in the tables are reduced.
9 Additional Information 9.4.3 Reduced overcurrent due to output frequency To protect the power unit at low output frequencies (<4.5 Hz) a monitoring system is provided, with which the temperature of the IGBTs (integrated gate bipolar transistor) due to high current is determined. In order to prevent current being taken off above the limit shown in the diagram, a pulse switch-off (P537) with a variable limit is introduced. At a standstill, with 6 kHz pulse frequency, current above 1.
SK 180E Manual for frequency inverters 9.4.4 Reduced output current due to mains voltage The devices are designed with thermal characteristics according to the nominal output currents. Accordingly, for lower mains voltages, higher currents cannot be taken off in order to maintain the stated power constant.
9 Additional Information 9.5 Operation with FI circuit breakers With frequency inverters (except 115V devices), leakage currents of up to 16mA are to be expected if the mains filter is active. These are designed for operation with leakage current circuit breakers for the protection of persons. For further details, please refer to Section 2.7.4. 9.6 System bus Frequency inverters and components communicate with each other via the system bus. This bus system is a CAN bus with CANopen protocol.
SK 180E Manual for frequency inverters Addressing If several frequency inverters are connected to a system bus, these devices must be assigned with unique addresses. This is preferably implemented via DIP switch S2 of the frequency inverter (Section 5.2.2.2). Frequency inverters FI 1 FI 2 FI 3 FI 4 Addressing via DIP switch S2 DIP2 DIP1 ON ON ON OFF OFF ON OFF OFF Resulting Node ID Frequency inverters 32 34 36 38 For field bus modules, no assignment of addresses is necessary.
9 Additional Information 9.7 Energy Efficiency NORD frequency inverters have a low power consumption and are therefore highly efficient. In addition, with the aid of "Automatic flux optimisation" (Parameter (P219)) the inverter provides a possibility for increasing the overall efficiency of the drive in certain applications (in particular applications with partial load).
SK 180E Manual for frequency inverters 9.8 Motor data - characteristic curves 9.8.1 50Hz characteristic curve ( Variation 1:10) a) 115V / 230 V frequency inverter The motor used for 50 Hz operation can be operated up to its rated point 50 Hz/230 V with the nominal torque. In spite of this, operation above 50Hz is possible, however the output torque reduces in a non-linear manner (see following diagram).
9 Additional Information b) 400 V frequency inverter The motor used for 50 Hz operation can be operated up to its rated point 50 Hz/400 V with the nominal torque. In spite of this, operation above 50 Hz is possible, however the output torque reduces in a non-linear manner (see following diagram). Above the rated point, the motor enters its field weakening range, as the voltage cannot be raised over 400 V when the frequency is increased above 50 Hz. Because of the mains voltage, maximum 400 V are available.
SK 180E Manual for frequency inverters 9.8.2 87Hz characteristic curve (only 400 V devices) ( Variation 01:17:00) The 87 Hz characteristic represents an extension of the speed adjustment range with a constant motor nominal torque.
9 Additional Information 9.8.3 100Hz characteristic curve (only 400 V devices) ( Variation 01:20:00) An operating point 100 Hz/400 V can be selected for a greater speed adjustment range with up to a ratio of 1:20. Special motor data are required (see below) that differ from the normal 50 Hz data. It must be ensured in this case that a constant torque is generated across the entire adjustment range but that it is smaller than the nominal torque for 50 Hz operation.

SK 180E Manual for frequency inverters 9.11 Maintenance and servicing information 9.11.1 Maintenance Instructions In normal use, frequency inverters are maintenance-free. Please note the "General data" in Section 8.1. Dusty environments If the frequency converter is being used in a dusty environment, the cooling-vane surfaces should be regularly cleaned with compressed air. If air intake filters have been built into the control cabinet, then these should also be regularly cleaned or replaced.
