V/I Input Point 1 Setting
/I
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 setting 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

• 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 settings.
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 signal 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.
