DirectDrive
Machines equipped with DirectDrive require special
attention with regard to operating environment.
• An especially dusty or linty environment will
require more frequent cleaning of AC inverter
drive cooling fan filter and of AC inverter drive
itself.
• Power line fluctuations from sources such as
uninterruptible power supplies (UPS) can
adversely affect machines equipped with AC
inverter drive. Proper suppression devices should
be utilized on incoming power to machine to
avoid problems.
• A clean power supply free from voltage spikes
and surges is absolutely essential for machines
equipped with AC inverter drive. Inconsistencies
(peaks and valleys) in power supply can cause
AC inverter drive to generate nuisance errors.
If voltage is above 230 Volt for 200 Volt
installation or 460 Volt for 400 Volt installation,
ask power company to correct. As an alternative,
a step-down transformer kit is available from
distributor. If voltage is above 240 Volt for 200
Volt installation or 480 Volt for 400 Volt
installations, a buckboost transformer is required.
• Sufficient space to perform service procedures
and routine preventive maintenance is especially
important for machines equipped with AC
inverter drive.
