DESCRIPTION OF PARAMETERS

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 230/240 Vac (on 240/200 Vac models), 460/480 Vac (on
480/400 Vac models), or 575/590 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.

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 - MIN FREQ,
and 11 - MAX FREQ).
The following table shows how each preset speed is selected using the TB-13
terminals. The terms OPEN and CLOSED refer to the state of the TB-13 terminal
relative to TB-2.
