Class 8839 58M Enclosed AC Drives
Specifications
Netscape Navigator. No additional software should be required.
2.The embedded
3.Standard Ethernet hubs, switches and routers can be used, although industrial grade devices are recommended if the environmental conditions warrant.
4.The Ethernet Communications Card shall support the following services via the standard Ethernet Port 502:
a)TCP/Modbus Client, with support for periodic I/O Scanning
b)HTTP Server for drive configuration, control, and monitoring.
c)ICMP client to support certain IP services such as the “ping” command.
d)BOOTP client to assign an IP Address via an address server.
5.The Ethernet Communications card shall have diagnostic LED that monitor communication
Note to Specifier: One of the following communication cards can be specified lieu of Ethernet Communication:
Modbus / Unitelway, Modbus Plus, LonWorks, Device Net, Johnson Controls METASYS N2, FIP I/O
2.14MESSAGE DISPLAY CENTER REQUIREMENTS
a.The message display center / keypad display shall be menu based and offer the modification of AC Drive adjustments via a touch keypad. All electrical values, configuration parameters, I/O assignments, application and activity function access, faults, local keypad control, and adjustment storage will be in plain English.
b.The display will be a
c.The AC Drive model number, torque type, software revision number, horsepower, output current, motor frequency and motor voltage shall all be listed on the drive identification display as viewed on the LCD display.
d.The keypad interface shall be configured to display selectable outputs such as speed reference, output frequency, output current, motor torque, output power, output voltage, line voltage, DC voltage, motor thermal state, drive thermal state, elapsed time, motor speed, machine speed reference and machine speed.
e.The operator terminal shall provide a main menu consisting of status, programming, drive configuration, and keypad operation. A hardware jumper lock shall protect drive setup from unauthorized personnel by limiting access to the programming and drive configuration menus. A software password shall be configured to limit access to all menus except status. The status menu shall show meters, I/O map, fault history and drive identification.
f.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.
g.A data entry key will allow the user to confirm a selected menu, numeric value or allow selection between multiple choices.
h.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.
i.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. The STOP key must be programmable for active in all control modes.
j.The keypad interface shall have three backlight colors to indicate functional status. A green color backlight will verify that the AC Drive is running. A red color backlight will indicate an AC Drive fault. An orange color backlight color will designate and idle or drive ready status.
k.The keypad and all door mounted controls must be [Type 1,Type 12] rated.
2.15EMERGENCY FULL SPEED REQUIREMENTS
a.The AC Drive shall include fully rated isolation and bypass contactors complete with Class 20 thermal overload relay protection for emergency full speed capability. Bypass and isolation contactor shall be mechanical and electrical interlocked. Emergency full speed bypass shall be [full voltage cross the line, solid state reduced voltage soft starter, reduced voltage autotransformer type.] Bypass and isolation contactors shall be in [Integrated, Barriered] construction.
1.Integrated bypass shall consist of integrating bypass and isolation contactors into the same enclosure compartment as the AC drive controller if space permits.
