A rectifier is a device that permits current flow in one direction and blocks the
flow of current in the other direction. In today's technology, rectifiers are of
the silicon diode type. The ACS 501 uses six rectifiers, configured into a
three-phase bridge configuration, as the power converter section of the drive.
Slip compensation is a feature in the ACS 501 that allows the drive to
compensate for motor slip caused by increased load.
Start-up Data parameters allow you to set certain parameter values prior to
starting the ACS 501. You set these parameters according to the language you
want the drive to display (such as German, Spanish, or English), the supply
voltage providing power to the drive, and so on. In most cases, these
parameters are one-time settings made only during the drive installation
process.
Start-up Data parameters are not accessed through the same display levels as
Operating Data parameters, Main level, or Group level. Instead, you must first
view Operating Data Parameter 1 (Output Frequency), press and hold [ * ] on
the Control Panel Keypad, then press [Right Arrow]. Only this procedure
accesses Start-up Data parameters on the ACS 501.
Supply voltage in this manual means the input voltage that provides power to
the ACS 501. Supply voltage is connected to ACS 501 Terminals L
