This parameter is used to set the communications reference for scaling.
See

F814
for additional information on this parameter.
Note:
Scaling the communications signal is not required for all
applications.
Changes made to this parameter require that the power be cycled (off then on)
for the changes to take effect.

When enabled at
F810
, this parameter is used to allow the user to set the gain
and bias of the speed control input to the ASD when the speed control signal is
received via the source selected at
F810
.
Gain and Bias Settings
When operating in the
Speed Control
mode and using one of the control
sources from
Settings
above, the settings that determine the gain and bias
properties of the input signal are:
•
Communications Reference Speed Setpoint 1
(frequency)
(
F812
),
• the communications
input signal value that represents
Communications
Reference Speed Setpoint 1
(frequency):
F811
,
•
Communications Reference Speed Setpoint 2
(frequency)
(
F814
), and
• the communications
input signal value that represents
Communications
Reference Speed Setpoint 2
(frequency):
F813
.
Once set, as the input signal value changes, the output frequency of the ASD
will vary in accordance with the above settings.
This parameter sets the
Communications Reference
input value that represents
Communications Reference Speed Setpoint 1
(frequency). This value is
entered as 0 to 100% of the
Communications Reference
input value range.
Changes made to this parameter require that the power be cycled (off then on)
for the changes to take effect.
