  11. ST130 | Parameter transfer to the control panel – What do I have to do?

    To transfer all parameters stored in the frequency inverter to the memory location of the control unit, proceed as follows: Go to […]

  12. ST130 | Warning light 230 V e.g. fault case – How to connect?

    A warning lamp with 230 V must be supplied externally. The warning lamp and the frequency converter are then connected in series. […]

  13. ST130 | Operation with minimum frequency – What do I have to do?

    Should the motor continue to run at a certain minimum frequency? Set F0.11 (lower frequency limit) between 0 Hz and the set […]

  14. ST130 | Power Class – Which model do I need?

    As a rule, the power class of the inverter should correspond to that of the motor. In the case of heavy starting […]

  15. ST130 | Initial commissioning – What do I have to observe (motor data)?

    Before commissioning a frequency inverter, it is essential that the factory settings are loaded y0.00 = 1. Then the rated motor data […]

  16. ST130 | Factory settings – How do I reset the inverter?

    To reset the ST130 frequency inverters to their factory settings, parameter y0.00 = 1 must be set. With 1, all parameters are […]

  17. ST130 | Forward, Reverse, Stop – Which parameters and terminal assignment?

    The ST130 frequency inverters have terminals DI1, DI2 and DI3 with which the inverters can be switched to forward and reverse operation […]
