F810
Frequency Point Selection
Program Communications Communication Reference Adjust
This parameter is used to set the communications reference for scaling.
See F811 — F814 for more information on this setting.
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.
Settings:
0 — Disabled
1 — RS485 (2-Wire — NOT USED)
2 — RS485 4-Wire
3 — Communication Card
Point 1 Setting
Program Communications Communication Reference Adjust
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 drive 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 drive
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.
Point 1 Frequency
Program Communications Communication Reference Adjust
This parameter is used to set the gain and bias of the Communications
Reference speed control input.
See F811 for more information on this setting.
This parameter sets Communications Reference Speed Setpoint 1.
Changes made to this parameter require that the power be cycled (off then on)
for the changes to take effect.
