DIP Selector Switches. Basic Operation. Before installing and putting this equipment into operation, please read these safety instructions and warnings carefully and all the warning signs attached to the equipment. Make sure that the warning labels are kept in a legible condition and replace missing or damaged labels. Children and the general public must be prevented from accessing or approaching the equipment! This equipment must only be used for the purpose specified by the manufacturer.

Unauthorised modifications and the use of spare parts and accessories that are not sold or recommended by the manufacturer of the equipment can cause fires, electric shocks and injuries. Keep these operating instructions within easy reach and give them to all users!

European Low Voltage Directive. The units are certified for compliance with the following standards:. EN Semiconductor converters - General requirements and line commutated converters Safety of machinery - Electrical equipment of machines. European Machinery Directive. A Declaration of Incorporation is available on request.

European EMC Directive. Underwriters Laboratories. ISO Siemens plc operates a quality management system, which complies with the requirements of ISO In order to ensure correct and safe operation, it is vital the following instructions are strictly adhered to:.

Operation of a motor with a higher nominal power than t he inverter or a nominal power less than half that of the inverter is not allowed. The inverter must only be operated when the nominal current in P exactly matches the motor rating plate nominal current.

If this instability occurs, the mains supply to the converter must be disconnected. When using the analogue input, the DIP switches must be correctly set and the analogue input type selected P before enabling the analogue input with P If this is not done, the motor may start inadvertently. Sensorless vector control allows the inverter to calculate the changes required in output current and frequency in order to maintain the desired motor speed across a wi de range of load conditions.

For additional product information such as application examples, part numbers, operation with long cables etc, please refer to catalog. Easy to install, program and commission. High starting torque and accurate motor speed regulation by vector control. Factory default parameter settings pre-programmed for European, Asian and North American requirements.

Output frequency and hence motor speed can be controlled by:. Frequency setpoint using the keypad. High resolution analogue setpoint voltage or current input. External potentiometer to control motor speed. Motorised potentiometer function. Serial interface. Built-in brake chopper for external resistor MMV. Two fully-programmable relay outputs 13 functions. Automatic recognition of 2,4,6 or 8-pole motors by software.

Integral software controlled cooling fan. Side-by-side mounting wit hout additional clearance. Environmental Requirements. Refer to DA64 Catalogue. Do not drop the inverter or expose to sudden shock. Do not install the inverter in an area where it is likely to be exposed to constant vibration. Electro- Do not install the inverter near sources of electro-magnetic radiation.

Do not install the inverter in an environment, which contains atmospheric pollutants such as dust, corrosive gases, etc. Take care to site the inverter away from potential water hazards. Do not install the inverter beneath pipes that are subject to condensation. Avoid installing the inverter where excessive humidity and condensation may occur.

Additional ventilation may be required for horizontal mounting. Ideal Installation. Figure: 1. Make sure that there is an adequate air-flow through the cabinet, as follows:. If necessary, install cabinet cooling fan s.

Note :. Note: The Plastic Material of the case can be degraded by oil or grease. Care should be taken to ensure that the mounting surface and fixings are thoroughly degreased before use. The inverters are designed to operate in an industrial environment where a high level of Electro-Magnetic Interference EMI can be expected. Usually, good installation practices will ensure safe and trouble-free operation.

If problems are encountered, the fo llowing guidelines may prove useful. In particular, grounding of the system at the inverter, as described below, may prove effective. Figures 1. Ensure that all equipment in the cubicle is well earthed usi ng short, thick earthing cable connected to a common star point or busbar.

It is particularly important that any control equipment that is connected to the inverter such as a PLC is connected to the same earth or star point as the inverter via a short, thick link.

Flat conductors e. The return earth from motors controlled by the inverter should be connected directly to the earth connection PE on the associated inverter. Wherever possible, use screened leads for connections to the control circuitry. Terminate the ends of the cable neatly, ensuring that unscreened wires are as short as possible. Use cable gl ands whenever possible. Separate the control cables from the power connections as much as possible, using separate trunking, etc.

Varistor suppressors are also effective. This is particularly important if the contactors are controlled from the relay on the inverter. Use screened or armoured cables for the motor connecti ons and ground the screen at both ends via the cable glands. If the drive is to be operated in an Electro-magnetic noise-sensitive environment, the RFI filter should be used to reduce the conducted and radiated interference from the inverter. For optimum performance, there should be a good conductive bond between filter and metal mounting plate.

For Frame Size A units Fig. Figure 1. On no account must safety regulations be compromised when installing inverters! These drive units can also be operated on non-grounded line supplies. However, we do not recommend this. However, if the drive units are operated on non-grounded line supplies, then the following points must be carefully observed:.

It is mandatory that line reactors are used. They are used to adapt line impedances and to minimize voltage peaks. It is also mandatory to use output reactors. The max. The drive unit is shutdown with fault F overcurrent if one or several output conductors develop a ground fault. The maximum clock cycle frequency is 2kHz. Only non-filtered drive units may be used. We recommend that ground fault monitoring devices are used at the incoming supply which can detect ground faults at the drive converter output If necessary, an insulating transformer should be used.

Drive inverters can be operated with residual-current protective devices under the following conditions:. Residual-current protective devices with mA type A are permissible. Universal residual-current protective device with mA type B must be used. Only one drive inverter may be connected to a residual-current protective device. The neutral conductor of the line supply must be grounded.

The motor cables may not be longer than 50m when shielded or m when non-shielded. The pulse frequency P may not exceed max. Installation after a Period of Storage.

It is necessary to reform the capacitors in the in verter if the unit has been stored for a prolonged period:. Period of storage 1 year old or less:.
