38 P9 ASD Installation and Operation Manual
Command Mode and Frequency Mode
Control
Command control includes instructions such as Stop , Run , Jog , etc. The source of the Command
signal must be established for normal operation.
Frequency commands control the output speed of the P9 ASD. The source of the frequency control
signal must be established for normal operation.
The source of the command control and frequency control may be either internal or external. Once the
source signal is selected for either function, the system may be configured to use the selected signal all
of the time or switch under user-defined conditions.
Command and Frequency control may be carried out using any one of several control methods (signal
sources) or combinations thereof. In the event that multiple control commands are received, the signal
sources are assigned priority levels. The primary control method for
Command and Frequency control
uses the settings of F003 and F004 , respectively.
Command Control ( F003 )
The Command Mode selection of F003 establishes the
primary source of the command input for the ASD.
However, the
Override feature may supersede the F003
setting as indicated in Table 4 on pg. 40 .
Table 4 shows the hierarchy of the control sources
managed by the Override function. The level of the
control item of the hierarchy is listed from left to right,
most to least, respectively. As indicated in the table, the
Override setting may supersede the F003 setting.
Placing the EOI in the Hand mode selects the RS485 (2-wire) as the Command Mode control source.
Hand mode operation may be superseded by other Override settings.
Example: With the EOI set to Hand , Communication Board input or RS485 (4-wire) input will
supersede EOI control input.
The remaining control sources may be placed into the Override Mode using communications.
The source of the Command control signal may be selected by:
• The F003 setting,
• Placing an item from the Command signal source selections in the Override Mode via
communications, or
• Placing the EOI in the Hand mode (places only the RS485 [2-wire] or the RS485 [4-wire] in the
Override Mode).
Possible Command signal source selections include the following:
• Terminal Block (default),
• EOI Keypad,
• RS485,
• Communication Option Board, or
• F003 setting (used if no signal sources are in the Override Mode).
Note: The Terminal Board is placed in the Override Mode for Command functions by
activating a discrete terminal that is assigned to Command Terminal Board Priority .
