2.09 Operator Interface
a. The operator interface terminal will offer the modification of AC drive adjustments via a touch keypad.
All electrical values, configuration parameters, drive menu parameters, application and activity
function access, faults, local control, adjustment storage, self-test, and diagnostics will be shown.
There will be a standard selection of four additional languages built-in to the operating software as
standard.
b. The display will be a high resolution, LED screen capable of displaying four 7-segment LED’s for
display of numerical values and codes in combination with a 16-character LCD display for messages.
c. The AC drive keypad will announce horsepower and voltage.
d. The display shall be capable to be configured to display multiple parameters with numeric data that
is selectable and scalable by the operator. A user defined display value proportional to output
frequency shall be available. As a minimum the display values shall consist of speed reference,
output frequency, output current, motor torque, output power, output voltage, line voltage, motor
thermal state, drive thermal state, motor speed, and process speed.
e. The keypad must allow dynamic switching between display variables.
f. The terminal keypad will provide the means of holding four different sets of drives parameters. The
functions will allow both operating commands and programming options to be preset by the operator.
g. A hardware selector switch will allow the terminal keypad to be locked out from unauthorized
personnel.
h. The keypad display will offer a general menu consisting of parameter setting, fault display, and drive
configuration. A software lock will limit access to the main menu. The main menu will consist of
keypad configuration, drive configuration, general configuration, diagnostic mode, and AC Drive
initialization screens.
i. There will be arrow keys that will provide the ability to scroll through menus and screens, select or
activate functions or increase the value of a selected parameter.
j. A data entry key will allow the user to confirm a selected menu, numeric value or allow selection
between multiple choices.
k. An escape key will allow a parameter to return the existing value if adjustment is not required and
the value is displayed. The escape function will also return to a previous menu display.
l. A RUN key and a STOP key will command a normal starting and stopping as programmed when the
AC drive is in keypad control mode.
m. The AC drive shall have 2 LED’s mounted on the front panel to indicate functional status. A green
LED will verify that the AC drive power supply is on. A red LED indicator will indicate an AC drive
fault.
n. A hand-held pocket PC operator interface shall be available for remote programming, diagnostics
and troubleshooting, and I/O Map display of terminal connections. The hand-held pocket PC shall
allow storage of eight drive set-up configurations, allow for the uploading and downloading of
configurations between AC drives or to a personal computer. Memory shall be non-volatile
o. A user interface shall be available that is Windows ® software based for use with personal computer,
serial communication link, or detachable operator interface.
2.10 CONTROL
a. a. External pilot devices shall be able to be connected to a terminal strip for starting/stopping the AC
Drive, speed control, and displaying operating status. Control inputs and outputs will be software
assignable.
b. 2-wire or 3-wire control strategy shall be defined within the software. External relays or logic devices
will not be needed to implement 3-wire control.
c. The control power for the digital inputs and outputs shall be 24 Vdc.
d. The internal power supply incorporates an automatic current fold-back that protects the internal
power supply if incorrectly connected or shorted. The transistor logic outputs will be current-limited
and not be damaged if shorted or excess current is drawn.
e. All logic connections shall be furnished on pull-apart terminal strips.
