Maintenance
The ULTRA 200 Series drive is designed to function with minimum
maintenance.
Periodic Maintenance
Normally the only maintenance required is removal of superficial dust
and dirt from the drive and a quick check of cable insulation and
connections.
Cleaning
To clean the drive, use an OSHA approved nozzle that provides
compressed air under low pressure <20 kPa (30 psi) to blow the
exterior surface and the vents clean.
Cable Inspection
Inspect the connections, particularly the power connections, to ensure
their tightness.
●
All power connections should be torqued to 1.4 Nm (12 lb-in).
●
D-shell signal connectors can be inspected for proper seating.
●
Visually inspect all cables for abrasion.
Fuse Replacement
The +24VDC, +5VDC and Motor Encoder power lines are fused for
protection. All fuses are 1A fast acting fuses, Refer to Appendix A,
“Options and Accessories” for the part number and Figure 11.1 for
fuse locations. A spare fuse, F4, is included on the circuit board for
convenience.

Intro
ATTENTION: DC bus capacitors may retain hazardous
voltages for several minutes after input power has been
removed, but will normally discharge in several seconds.
Measure the DC bus voltage to verify it has reached a safe
level each time power is removed before working on the
drive; or wait for the time indicated in the warning on the
front of the drive.
Failure to observe this precaution could result in severe
bodily injury or loss of life.
