To the left operation in one direction To the right operation in one direction 4 7 Thermal protection of the drive Protection limit 12t The built in thermal model of the drive enables to calculate temperature of the drive in the theoretical way The Model is developed on the basis of the following assumptions the temperature of windings changes according to exponential law the drive achieves the maximal temperature for continuous work at a rated current change of temperature depends on a ratio I In 2 the constant of time of cooling for stopped drive is four times more than a constant of time of heating during operation Fig 4 17 Definition a Dependence of calculated temperature from motor s current b and c Relative long term motor current value for frequency higher then 25 Hz is determined by parameter 3 3 For frequency lower then 25 Hz long term current is lower smaller efficiency of the cooling fan which is placed on a drive shaft and it is determined by parameter 3 4 These parameters are determined in comparison with rating value of a drive current for 100 0 96 In Thus the area of long term work fig 4 17a is defined When cooling the motor without additional ventilation only with the internal fan par 3 4 is necessary to set up on value of 35 96 of rated motor current If additional ventilation of the drive is used value of par 3 4 can be set up to 75 If the motor current is outside of

47. t touching live parts consists of automatic switching off by special short circuit protection or differential current protection or voltage limitation to a level not exceeding acceptable values in case of an insulation failure The short circuit to ground at the frequency converter output can be not detected by short circuit protection devices due to DC link circuit The protection against interpolar and ground short circuit on the output of the converter is provided However this protection is based on IGBT transistors blocking what does not conform to the requirements of fire prevention protection Due to that for safety of staff it is necessary to make local equipotential connections In the frequency converter there are provided appropriate terminals properly marked protected from corrosion to make equipotential connections Protection Use of gG or aM fuses is allowed in the circuits however taking into account necessity of protection of the rectifier bridge of the frequency converter the best solution is gR or aR fuses You can use overcurrent protection but the response time of such devices is longer than properly chosen fuse Frequency converter is protected from drive overloading motor overheating under and overvoltage in an DC link circuit of the converter a short circuit at the converter output it protects converter only Usage of differential current protection due to electrical shock prevention can appear unfavorable
