VI/II Reference Point 1
Program
Frequency
Speed Reference Setpoints
This parameter is used to set the gain and bias of the VI/II input
terminals when either terminal is used as the control input while
operating in the Speed Control or the Torque Control modes.
Note:
See note on
for additional information on the VI/II
terminal.
Perform the following setup to allow the system to receive control input at
the VI/II terminals:
•
Program
Fundamental
Standard Mode Selection
Command Mode Selection (0 = Terminal Board).
•
Program
Fundamental
Standard Mode Selection
Frequency Mode 1 (1 = VI/II).
•
Provide a Run command (F or R).
Gain and Bias Settings
When operating in the Speed Control mode, the settings that determine
the gain and bias of the VI/II terminals are:
•
VI/II Speed Frequency Setpoint 1
(
,
•
the VI/II input signal level that represents VI/II Speed Frequency
Setpoint 1 (
),
•
VI/II Speed Frequency Setpoint 2
(
, and
•
the VI/II input signal level that represents VI/II Speed Frequency
Setpoint 2
).
When operating in the Torque Control mode, the settings that determine
the gain and bias of the VI/II terminals are:
•
Torque Reference Setpoint 1
(
)
,
•
the VI/II input signal level that represents the VI/II Torque
Reference Setpoint 1 (
),
•
Torque Reference Setpoint 2
(
)
,
•
the VI/II input signal level that represents Torque Reference
Setpoint 2 (
).
Once set, as the VI/II input changes, the output frequency or the output
torque of the drive will vary in accordance with the above settings.
This parameter sets the VI/II input level that represents VI/II Speed
Reference Setpoint 1
(torque or frequency). This value is entered as 0 –
100% of the VI/II input signal range.
The input signal may be trimmed using
(Bias) and
(Gain).
The default value for this parameter (
) is 20%. The II input is
commonly used for the 4 – 20 mA current loop signal where 4 mA
equals 20% of a 20 mA signal. If the VI input is used (0 – 10 VDC input),
parameter
may be changed to 0.0% (of the input signal).
