V/I Input Point 1 Setting

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
of the
Terminal Board
to
Voltage
or
Current
(see
Figure 9 on
pg. 23
).

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
.
