ABB ACS580-07 - Protecting the Drive against Ground Faults; Residual Current Device Compatibility; Implementing the Emergency Stop Function; Implementing ATEX-Certified Thermistor Protection

Protecting the drive against ground faults
The drive is equipped with an internal ground fault protective function to protect the unit
against ground faults in the motor and motor cable. This function is not a personnel safety
or a fire protection feature. See the firmware manual for more information.
￭ Residual current device compatibility
The drive is suitable to be used with residual current devices of Type B.
Note:
As standard, the drive contains capacitors connected between the main circuit and the
frame. These capacitors and long motor cables increase the ground leakage current and
may cause nuisance faults in residual current devices.
Implementing the emergency stop function
The drive can be equipped with emergency stop function of stop category 0. For safety
reasons, install the emergency stop devices at each operator control station and at other
operating stations where emergency stop can be needed.
Note:
Pressing the stop key on the control panel of the drive, or turning the operating switch of
the drive from position "1" to "0" does not generate an emergency stop of the motor or
separate the drive from dangerous potential.
See the user’s manual for the wiring, start-up and operation instructions.
