System Parameters 1 through 6.
V/F Curve button (not available for the IRADK31 Motor Controller Board).
Motor Parameters
These are generally self-explanatory. Information on the motor hardware itself (items 1
through 6) can be found on the motor’s nameplate or in its data sheet. The “Motor Type”
filed is auto-populated with the motor type identified upon connection.
Selecting the appropriate check boxes in “Feed back Devices” selectively enables the
configuration for motion feedback sensors. When only “Hall Sensor” check box is selected
the sensor angle and Motion Filter Prescaler (MFM) may be configured; the other options
are disabled. When optical encoders are enabled, the Encoder PPR (pulses per
revolution), and MFM Filter may be configured; Hall Sensors configuration is unavailable.
QEI update mode is default to X4 and cannot be changed. The recommended setting for
the MFM Filter Prescaler to be used with the IRADK31 is “Filter Disabled”.
Note that the Hall Sensors and optical sensors are not mutually exclusive. It is possible for
some control methods to use both types at once.
For the IRADK31, only the Hall Sensor
option is available.
Selecting the “None” option in “Feed back Devices” disables all
sensor configuration options. Information on the sensor type and arrangement can be
found in the motor data sheet.
System Parameters
The system parameters options can only be used with BLDC motors with the firmware
provided with this demo kit.
Acceleration and deceleration rate are defined as RPS/sec for most applications.
Input voltage is the AC input voltage applied to the board. The input voltage should be kept
at 220VAC, regardless of actual AC input applied. Because the board has a voltage
doubler on the input rectifier side, when 115/120VAC is supplied, the DC Bus volrage
would be 320V with voltage doubler circuit. When the input voltage is 220/230V AC, the
DC Bus volrage would also be 320V without voltage doubler circuit.
The calculated DC Bus voltage supplied to the buck converter is given as 2 times the AC
input (when 120VAC is applied) times 1.414, with the on-board voltage doubler enabled.
When the on-board voltage doubler is not used and 230VAC is applied to the board the DC
Bus voltage would be 230V times 1.414.
The PWM frequency determines the resolution of the control firmware. The drop-down
combo box presents a fixed range of values.
