Supplemental GUI Content
The following step numbers correspond to the step
numbers in the “How to use the GUI” section in the Quick
Start Guide.
13. Voltage Reading Function
READ to display the voltages in the pink column.
VREF
… Output Motor Current Reference Voltage
Displays the reference voltage for 5 Output motor
current setting
VREF = (Output Motor current) × 5 × 0.22 W
14. Status Check Function
The red lamps and counters indicate the status
detected by the LV8702 from the outputs of each
terminal (DST1, DST2, MONI) of the LV8702.
When the Real Time Update is turned on, the
outputs from the terminals are periodically Read
and displayed.
Close to Stall and Stall Detected are enabled when
the high
− efficiency drive function is set to
Efficiency = High, and the number of times of
occurrence is displayed in boxes.
This count is reset by pressing Clear.
(Maximum count = 255)
When the Real Time Update is turned off, the
status when the Read button is pressed is
displayed.
Normal:
Normal conditions (DST1:H, DST2:H)
Close to Stall:
Electrical detection of danger of stall
(DST1:H, DST2:L)
Stall Detected:
Electrical detection of stall state
(DST1:L, DST2:H)
Warning:
Detects the state of short
− circuit between the OUT
terminal and the power supply and GND of the
OUT terminal and the IC overheat state
(DST1: L, DST2: L).
Step Pulse Receive Error:
Detects (MONI) positional deviation of the motor
caused by noise
− jumping into the STEP input
terminal of the LV8702.
About Warning:
When the overheat protection function is activated,
all OUTs turn OFF and the motor stops.
When the temperature drops, the Warning state is
released and the motor drive is restarted.
When the short
− circuit protection function of the
OUT terminal is activated, all OUTs are turned
OFF and the motor stops.
This condition can be reset by switching Chip
Enable/ Disable from Operation to Standby to
Operation.
15. GUI Language Settings
