8.8 FAQ Pertaining to the Utility Software
This section describes the frequently asked questions (FAQ) pertaining to the utility software.
Updated Parameters are not Stored.
Writing data to a parameter (e.g., #1=2) changes only that value in RAM of the drive.
Therefore, that data is erased when the power is turned OFF. If you want to store updated
data, rewrite the parameter in EEPROM (e.g., ##1=2), or write all parameters using the @16
command.
The Utility Software Stops during Waveform Display due to a Communication Error.
Insufficient performance of your PC may be the cause. Check if the operating conditions are
met. Close all other applications if possible. Especially, if you are using the oscilloscope
function, it uses up more CPU power than any other functions.
If a communication error still occurs, change the communication cycle to a slower cycle.
However, in such a case, the oscilloscope function cannot be used.
A Communication Error Occurs while Using the Oscilloscope Function for an Extended Period in Windows
98.
Particularly in Windows 98, it seems there is a time contention problem between the power
supply monitor interrupt and the communication port interrupt. When using the oscilloscope
function, disable all power supply monitor related functions.
Waveforms Different from Expected Waveforms were Obtained when the Time Axis was set to a Long
Range.
Especially when the time axis is set to a long range, waveforms different from actual
waveforms may be obtained especially relating to sampling. Always take account of an
aliasing problem before using.
Communication Errors Occur Frequently on a USB-RS232C Converter.
Some converters may not operate correctly in this system. In particular, failure to receive data
occurs with the frequently communicated oscilloscope function. Also, an error may occur
during communication with the drive connected to the COM port of a PC due to the effect of
the drive software's in the converter.
How can I Control the Drive from a PC Using an RS232C/485 Port?
We have control DLL for this purpose. You can create an application that controls multiple
drives in Visual Basic from your PC by installing this control DLL. For more information,
contact our Support Desk.
Installation Failed in Windows 98.
The utility software is supported in Windows 98 Second Edition or higher.
How can I Update Various Resource Files?
We periodically update the PDF and CSV files referenced from the utility software. To update
these files on your system, download the latest versions from our Web site and overwrite
them into the install folder.
