8.2.6 Scale correction
This is the function of correcting the motor speed measured value and control output when the motor
speed measured value differs from the actually measured value or motor speed set value differs from
the actually measured value.
H-SIO-A correction trigger:
Sets whether correction is executed.
Setting
rage:
0:
Normal
1:
Correction
executed
2: Correction canceled (Return to motor speed measured value and control
output value before correction.)
When the power is turned on, setting is 0.
H-SIO-A correction actual measured value:
Sets the actual measured value at scale correction.
Setting rage: Within display scale range
[ Operation procedure ]
1.
Sets the actual measured value to H-SIO-A correction actual measured value.
2.
Sets the 1 to H-SIO-A correction trigger.
Scale correction is executed, and then control output and motor speed measured value are revised.
When conducting the correction again, re-set the H-SIO-A correction actually measured
value, and then set the H-SIO-A correction trigger to 1 after it is set to 0 once.
The correction can be conducted in the open and closed loop control states. However, it is
recommended that the correction be conducted in the open loop control state as the output
becomes constant and stable under this state.
Conduct the correction within the range of
±
5 % . If the correction exceeding 5 % is required,
adjust the display and output scales.
Processing time of correction execution or cancel is about 1 second. Do not turn OFF the
power during the processing time. In addition, maintain the setting more than 0.5 second in
order to let it recognize modification in setting modification.
