Frequency Control (F004); Frequency Control Selections - Toshiba WX9 ASD Installation & Operation Manual

Frequency Control (F004)

The Frequency Mode 1 (or the Frequency Mode 2) setting establishes the user-selected source of the
control input for the ASD frequency. The signal source selected here is used for speed control unless the
Reference Priority Selection parameter is configured to automatically switch this setting (see F200) or
if the Override feature is enabled (via communications or via the Hand mode operation).
The source of the Frequency control signal may be selected by:
• The F004
• Placing a signal source in the Override Mode via communications, or
• Placing the EOI in the Hand mode (places only the RS232/RS485 or TTL in the Override
Mode).

Frequency Control Selections

The following is a listing and description of the
Frequency Mode (F004) selections (Program 
Fundamental  Standard Mode Selection  Frequency
Mode 1).
Settings:
1 — VI/II
0 to 10-volt DC analog input connected to VI or a 4 – 20 mA (or 0 to 1 mA) DC current
connected to II (cannot use both simultaneously).
2 — RR (default setting)
0 to 10-volt DC analog input connected to RR.
3 — RX
-10 to +10-volt DC analog input connected to RX.
4 — RX2
-10 to +10-volt DC analog input connected to RX2.
5 — CN8
Allows for Frequency control input via the CN8 connector of the Control Board.
6 — Binary/BCD Option
Allows for discrete input terminal input to control the ASD output.
7 — Common Serial (TTL)
To use the EOI for control requires that the
8 — RS232/RS485
To use the EOI for control requires that the
9 — Communication Option Board
Routes the control and monitoring I/O to CNU3 of the Control Board of the WX9 ASD (Option
Card connector).
10 — UP/DOWN Frequency
Discrete input terminals may be configured to increase or decrease the speed of the motor by
momentarily connecting the assigned discrete input terminal to CC. See
Function on pg. 81
11 — Pulse Input (option)
Configures the system to receive pulse input. See PG Speed Reference Setpoint on
