PAGES 5 THRU 8 – MAXIMUM VALUES
These pages are used to display the maximum value of
certain VSD readings. Along with the value, the date and
time the maximum value occurred are also displayed. The
password is required to view these values.

Reset Values –
This is the only setting in the group. It is used
to reset the above maximum values to 0.
PAGES 9 AND 10 – VSD SETUP
These pages are used to make adjustments to the VSD or
enable some functions. The password is required to modify
these settings.
Maximum Motor Speed –
This is read only and is used to
display the maximum motor speed.
Minimum Motor Speed –
This is read only and is used to
display the minimum motor speed.
Proportional Gain –
Used to adjust the proportional gain of
the controller’s PID.
Integral Gain –
Used to adjust the integral gain of the
controller’s PID.
Control D Factor –
Used to adjust the derivative gain of the
controller’s PID.
Ramp Rate –
Used to adjust the PID’s ramp rate.
Skip Speed Point –
This is used to set the mid-point of the
skip speed band.
Skip Speed Band –
This is used to set the range of the skip
speed band.
Minimum Speed Offset –
This setting is used to raise the
minimum speed.
Variable Speed Delay –
This setting is adjustable from 0 to
60 seconds. When set to a value greater than 0, the controller
will limit the compressor to minimum speed for this time
period after starting. At the end of this time period, the
controller will resume PID control.
Idle Mode –
This setting is used to select idle mode
operation.
