Default values depend on the macro used. Values specified are for the default macro. See chapter
Application macros
Note: Terminals 3, 6 and 9 are at the same potential.
Note: For safety reasons the fault relay signals a "fault" when the ACS550 is
powered down.
WARNING! All ELV (Extra Low Voltage) circuits connected to the drive must be used
within a zone of equipotential bonding, i.e. within a zone where all simultaneously
accessible conductive parts are electrically connected to prevent hazardous voltages
appearing between them. This is accomplished by a proper factory grounding.
The terminals on the control board as well as on the optional modules attachable to
the board fulfil the Protective Extra Low Voltage (PELV) requirements stated in
EN 50178, provided that the external circuits connected to the terminals also fulfil
the requirements and the installation site is below 2000 m (6562 ft).
You can wire the digital input terminals in either a PNP or NPN configuration.
