Display Type Menu The DISPLAY TYPE menu is the top level of the menu tree. This will
always be the initial top line display when power is first applied to the
drive and after the Reset input has been given.
METER DISPLAY
This is a menu title for all of the parameters that can be displayed in digital
meter form on the drive display. The following paragraphs describe the
function of each item.
Motor Speed
When selected, the display will show the actual bipolar motor speed as
measured from the resolver feedback.
Data Format: RPM 00000
Spindle Speed
Displays the actual spindle speed as calculated from the programmed gear
ratio and actual motor speed. The display is bipolar.
Data Format: RPM 00000
% Load
Indicates the percent rated motor load. The displayed data is determined
from the torque command with continuous rated motor torque from zero
speed to base speed, and continuous rated power output from base speed to
maximum speed. This will give the same 100% output reading. The
maximum reading shows the peak capability of the drive/motor
combination as a percent of the continuous rating and may vary for
different drive ratings. This is a unipolar output.
Data Format: %000
% Torque
When selected, the percent rated motor torque is shown. This is identical to
the % Load parameter except that it is a bipolar output.
Data Format: %000
Power Output
The motor output power expressed in kilowatts (kW) will be displayed. At
zero speed the motor power is zero regardless of the torque output. For a
percent load output equal to 100% throughout the speed range, the Power
Output will increase linearly from zero at zero speed to rated power at base
speed. It will then remain constant from base speed to maximum speed.
This is a unipolar output.
