NOTE: Application control from PC master software requires that PC master
software control mode must be set. Before changing PC master
software/manual control mode (by PC Master Mode Radio button) the
controller board START/STOP switch must be set to STOP. This is a
protection feature that prevents the motor from unexpected starts!
• Start the motor (Start Motor button)
NOTE: To start the motor with PC master software control mode, two conditions
must be fulfilled. START/STOP switch on the controller board must be
set to START and Start Motor button on PC master software control
page must be “pressed down”.
• Stop the motor (Stop Motor button)
• Set the required speed of the motor (via bar graph)
• Clear failures (Clear Failures button)
PC master software displays the following information:
• Required speed of the motor
• Actual speed of the motor
• dc-bus current
• Temperature of the power stage
• Fault status (no fault, over-voltage, under-voltage, or over-current
in dc-bus)
• Motor status — running/stopped
NOTE: Hardware board identification is not implemented in the software.
Therefore, the PC master software control window displays Power Stage
board, Optoisolation board: Not Recognized.
If the fault status is different from the no faults (when over-current,
over-voltage, or under-voltage fault), the red LED blinks and the motor is
stopped. This state can be exited by application RESET or Clear
Failures button on the PC master software control page.
NOTE: It is strongly recommended that you inspect the entire application to
locate the source of fault before starting it again.
