Direct Access Parameter Information
Q9 Plus ASD Install/Op Manual
V/I Input Point 1 Setting
Program Frequency Speed Reference Setpoints
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 Input Point 1 Frequency setting when operating in the Speed
control mode or is associated with the V/I Input Point 1 Rate set-
ting when operating in the Torque Control mode.
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 or Current (see
Figure 9. on pg. 17).
• Program Fundamental Standard Mode Selection
Frequency Mode 1 V/I.
• Program Fundamental Standard Mode Selection
Command Mode Selection Terminal Board.
Speed Control
Perform the following setup to allow the system to perform Speed
control from the V/I input terminal:
• Set V/I Input Point 1 Frequency (F202).
• Set V/I Input Point 1 Setting (F201) — the input analog signal
level that corresponds to the frequency setting at V/I Input
Point 1 Frequency.
• Set V/I Input Point 2 Frequency (F204).
• Set V/I Input Point 2 Setting (F203) — the input analog signal
level that corresponds to the frequency setting at V/I Input
Point 2 Frequency.
• Provide a Run command (F and/or R).
Once set, as the V/I input voltage or current changes, the output
frequency of the ASD will vary in accordance with the above set-
tings.
This parameter value is entered as 0% to 100% of the V/I input
signal range.
The V/I input is commonly used for a 4 – 20 mA current loop sig-
nal where
4 mA equals 20% of a 20 mA signal. Set this parameter to 20%
for 4 – 20 mA current loop signal applications.
Note: When using the isolated V/I input terminal, the IICC
terminal must be used as the return (negative) connection.
Note: If using P24 to power a transducer that is to be used to
supply the V/I input signal, it may be necessary to connect
IICC to CCA.
