Base Frequency 4
The Motor #4 Base Frequency setting determines the frequency at which the
output voltage of the ASD reaches its maximum setting. The maximum voltage
setting cannot be more that the input voltage (see the
parameter). There are four Base Frequency profile settings: #1 – #4.
This parameter is used only when the parameters for motor set #4 are
configured and selected. Motor set #4 may be activated via a properly
configured discrete input terminal.
For proper motor operation, the Base Frequency should be set for the name-
plated frequency of the motor.

BIN Speed Frequency #1

⇒
BIN Speed Ref 1
This parameter is used to set the direction, gain, and bias of the discrete input
terminals when using the discrete input terminals as the control input while
operating in the Speed Control mode.
BIN Input Speed/Direction Control Setup
Perform the following setup to allow the system to receive Speed control input
at the discrete input terminals:
•

•
Program
⇒
Input Terminals; select and set the desired discrete input
terminals to Bin Bit(s) 0 – 7 or 0 – MSB (see table
a listing of the available terminal settings). The binary terminal input word
will control the direction, speed, and torque of the motor.
•
Provide a Run command (F and/or R).
Speed/Direction Control
Perform the following setup to allow the system to perform Speed control from
the BIN input terminals:
•
Set BIN Speed Frequency #1,
•
Set the binary input value (% of 255
D
) (BIN Speed Ref #1) that represents
BIN Speed Frequency #1,
•
Set BIN Speed Frequency #2, and
•
Set the binary input value (% of 255
D
) (BIN Speed Ref #2) that represents
the BIN Speed Frequency #2.
Note: 255
D
is the decimal equivalent of the 8-bit BIN word with all
input terminals set to one (255 decimal = 11111111 binary).
Once set, as the BIN input word changes, the directional information and the
output frequency of the ASD will vary in accordance with the above settings.
This parameter sets BIN Speed Frequency #1 and is the frequency that is
associated with the setting of BIN Speed Reference 1.
