FR-F800 5 - 279
Method to adjust only stall prevention operation level without adjusting gain voltage (current).
(When changing the gain value from 150% to 130%.)
Operation
Parameter selection
Turn to choose " " (Pr. 920) for the terminal 1, and " " (Pr. 933) for the terminal 4.
Press to show the present set value. (150.00%)
Changing the stall prevention operation level
Turn to change the set value to " ". (130.00%)
Press to enter the setting. " " and " ( )" flicker alternately.
Checking the mode/monitor
Press three times to change to the monitor / frequency monitor.
Start
Turn ON the start switch (STF or STR) to apply a voltage across terminals 1 and 5 (4 and 5).
Operation is performed with 130% stall prevention operation level.
Tab. 5-124: Adjusting only the stall prevention operation level without adjustment of a voltage
(current)
NOTES If the gain and bias of the stall prevention operation level setting are too close, an error ("Er3") may
be displayed at setting.
For operation outline of the parameter unit (FR-PU07), refer to the Instruction Manual of the
FR-PU07.
Set the bias setting using the calibration parameter C16 (Pr. 919) or C38 (Pr. 932). (Refer to page 5-
275.)
