18.0 DESCRIPTION OF PARAMETERS
0 LINE VOLTS (LINE VOLTAGE)
This parameter calibrates the drive for the correct input voltage, and can be set to AUTO,
HIGH, or LOW.
When set to AUTO, the drive measures the DC bus voltage when power is applied and
automatically calibrates itself according to the measured value (DC bus voltage is equal to
input voltage multiplied by 1.4).
This parameter can also be set “manually”, using the HIGH or LOW settings. For actual line
voltages of 220 - 240 Vac (on 240/200 Vac models), 460 - 480 Vac (on 480/400 Vac models),
or 575 - 600 Vac (on 590/480 Vac models), set this parameter to HIGH. Also use the HIGH
setting for 240/120 Vac single-phase input models. Refer to the table below.
For actual line voltages of 200 - 208 Vac (on 240/200 Vac models), 380 - 415 Vac (on
480/400 Vac models), or 460 - 480 Vac (on 590 Vac models), set this parameter to LOW.
Refer to the table below.
1-4 SPEED #1- #4 (PRESET SPEEDS #1, #2, #3, AND #4)
PRESET SPEEDS are only active when the drive is in AUTO mode, and are activated via
contact closures between terminal TB-2 and terminals TB-13A, TB-13B, and TB-13C.
These terminals must be programmed as preset speed selects using Parameters 47 - 49:
TB13A, TB13B, and TB13C.
The preset speeds can only be set to values that are within the operating range defined by the
minimum and maximum frequency (see Parameters 10 and 11).
