5-3-13 Supplemental Information
Restrictions
• Inverter positioning 0 and inverter positioning 1 each use one high-speed
counter and one serial port (except that a serial port is not used when an
Analog Output Unit is used). (High-speed counter 0 is allocated to inverter
positioning 0 and high-speed counter 1 is allocated to inverter positioning
1.)
• When inverter positioning 0 or 1 is used, the corresponding pulse output
(0 or 1) and the corresponding PWM command (pulse output 0 or 1) can-
not be used.
Precautions
• Determine the in-position range based on the mechanical system. Use a
smaller range if positioning precision is required. If the range is too small,
however, time may be required when stopping. If stopping quickly is more
important than precision, increase the in-position range.
• The error counter cycle also affects the conversion between the output
value and the inverter frequency command value. Refer to
5-3-9 Auto-
matic Calculation of Inverter Frequency Command Value
for details.
• If inverter positioning does not end normally, adjust the following settings.
Reduce the acceleration/deceleration rates.
Lower rates will stabilize operation at the end of acceleration/deceleration.
Reduce the target frequency.
Change the error counter cycle. Increasing the error counter cycle improve
stopping precision, but it may also cause unstable speeds during opera-
tion.
Adjust the gain.
Increasing the gain will improve stopping precision, but it may also cause
unstable speeds during operation.
