Q9 ASD Installation and Operation Manual 83
V/I Reference 1
Program Frequency Settings
This parameter is used to set the gain and bias of the isolated V/I input terminal
when the V/I terminal is used as the control input while operating in the Speed
Control mode or the Torque Control mode.
This parameter sets the V/I input level that is associated with the V/I Frequency 1
setting when operating in the Speed control mode or is associated with the
V/I Torque Reference 1 setting when operating in the Torque Control mode.
Note: See note on pg. 40 for more information on the V/I terminal.
V/I Input Speed Control Setup
Perform the following setup to allow the system to receive Speed control input at
the V/I input terminal:
•Set SW301 of the Terminal Board to Voltage if using a control voltage or to
Current if using a control current (see Figure 9 on pg. 22).
• Program Utility Group Frequency Mode 1 V/I.
• Program Utility Group Command Mode Terminal Block.
Speed Control
Perform the following setup to allow the system to perform Speed control from
the V/I input terminal:
•Set V/I Frequency 1 (F202).
•Set V/I Reference 1 (F201) — the input analog signal level that corresponds
to the frequency setting at V/I Frequency 1.
•Set V/I Frequency 2 (F204
).
•Set V/I Reference 2 (F203) — the input analog signal level that corresponds
to the frequency setting at V/I Frequency 2.
• Provide a Run command (F and/or R).
Once set, as the V input voltage changes or the I input current changes, the output
frequency of the ASD will vary in accordance with the above settings.
This parameter value is entered as 0% to 100% of the V/I input signal range.
Note: When using the isolated V/I input terminal the IICC terminal must
be used as the return (Negative) connection.

V/I Frequency Settings
V/I Frequency 1
Program Frequency Settings
This parameter is used to set the gain and bias of the isolated V/I input terminal
when the V/I terminal is used as the control input while operating in the Speed
Control mode.
This parameter sets V/I Frequency 1 and is the frequency that is associated with
the setting of V/I Reference 1 when operating in the Speed Control mode.
See V/I Reference 1 (F201) for more information on this setting.
