TROUBLESHOOTING
This section contains four troubleshooting flowcharts to help you resolve four possible
system operating problems. The four scenarios that are addressed by the flowcharts
are:
Motor Does Not Stop
Motor Does Not Run
Motor Runs at Wrong Speed
Motor Runs Unstable
If you need to verify the integrity of the ML–Drive independently, refer to the
Troubleshooting: Diagnostics section, page 4-3.
If these troubleshooting procedures do not solve your problem, perform a “Clear/7”, as
follows:
• Make a record of your current Control Parameter values. When you
perform the Clear/7 procedure, all Control Parameters return to the default
values.
• Turn off the power to the ML-Drive.
• Press the “Clear” key and the “7” key, then continue to press these keys
while you apply power to the ML-Drive. The “Clear 7” procedure restores
the factory default settings and automatically performs the Power Up
diagnostic routines.
• Reenter the values for your Code Parameters.
