3 Configuration menus and parameters
3.1.1
Setup Menu - item entry
When in each of the menu items you will be asked to respond to a question. For
example: “Enter 33.3 rpm frequency, Hz: (45 – 65): 50.0”. The question will be
followed by the units, the range of acceptable values in between the brackets (45 -
65), and finally the current value: 50.0. Either provide a new value within the range
specified or press the Return key (CR) to accept the current value. The section
questions will repeat until the Q key is pressed. The Q key can pre pressed at any
time, not just at the end of a section to exit the current setup menu.
3.1.2
System Parameters
Configuration items in this menu relate to general behaviour of the overall controller.
If you live in the UK and are using a 110v synchronous motor, then the default values
should work fine. Worldwide users may need to set the 33.3 & 45 rpm frequencies:
Parameter / Description
Units
Range
Default
value
Enter 33.3 rpm frequency, Hz:
The frequency that needs to be supplied to the
motor to achieve 33.3 rpm rotation
Hz
30-65
50
Enter 45 rpm frequency, Hz:
The frequency that needs to be supplied to the
motor to achieve 33.3 rpm rotation
Hz
65-90
67.5
Soft start frequency delta, Hz:
The difference from the 33.3 rpm starting
frequency when first powered on.
Hz
0-30

How many phases on motor:
The number of windings on the motor you are
controlling. Most synchronous motors are 2
phase. Three and four phase motors require an
additional expansion board that contains
additional DDS generators and motor amplifiers.

Motor full speed voltage, %:
When the motor is running at full speed (WOW
<=0.02%) the voltage drive can be reduced in
order to reduce motor vibration. This parameter
will reduce the drive from 100% to the specified
value. Keep at 100% if feature is not used. You
must have a platter sensor for this function to
work.

Power standby sleep time, min:
If the motor drive is idle (not spinning) for longer
than the specified period, the board switches to
low power/sleep mode. It is woken by pressing
