Operating Instruction - Frequency Inverter 230V / 400V ... - opis.cz

Contact-controlled:If the parameter Braking Time 632 is set to the value 0.0 s, the direct current brake iscontrolled by the Start clockwise and Start anticlockwise signals. The time monitoringand limitation by Braking Time 632 are deactivated. The braking current flows up tothe logical status 0 (low) of the controller release (S1IND).ParameterSettingsNo. Description Min. Max. Fact. sett.632 Braking Time 0.0 s 200.0 s 10.0 sTo avoid current surges, which can possibly lead to a fault switch-off of the frequencyinverter, a direct current may only be impressed into the motor after the motor hasbeen demagnetized. As the demagnetization time depends on the motor used, it canbe set with the parameter Demagnetizing Time 633.The selected demagnetizing time should be approximately three times the Act. RotorTime Constant 227.ParameterSettingsNo. Description Min. Max. Fact. sett.633 Demagnetizing Time 0.1 s 30.0 s 5.0 sThe selected stopping behavior is supplemented by a current controller to control thedirect current brake. The PI controller checks the current impression of the set BrakingCurrent 631. The proportional and integrating parts of current controller can beadjusted via parameters Amplification 634 and Integral Time 635, respectively. Thecontrol functions can be deactivated by setting the parameters to 0.ParameterSettingsNo. Description Min. Max.

By activation of the auto-start function via parameter OperationMode 651, the frequency inverter accelerates the drive after connection of the mainsvoltage. The controller release signal and the start command are necessary accordingto the regulations. When the motor is switched on, it is accelerated according to theparameterization and the reference value signal.Operation mode0 - Off1 - Switched onFunctionThe drive is accelerated, after application of the mainsvoltage, as soon as the controller release signal and thestart command are present.The drive is accelerated by the frequency inverter as soonas the mains voltage is applied.Warning!Comply with VDE provision 0100 part 227 and provision 0113, in particularSections 5.4, protection against automatic after main line voltagefailure and voltage recovery, and Section 5.5, undervoltage protection.Appropriate measures must be taken to exclude any risk for staff, machinesand production goods.In addition to that, all specific regulations relevant to the application aswell as all national directives are to be complied with.02/06 89
