Maintenance and diagnostic functions toprevent unexpected downtime

ZDT

Robot Maintenance andDiagnostic functions using
IoT technology

ZERODOWN TIMEZDT(Zero Down Time) is a proven IoT solution
designed to eliminate unexpected downtime on the factory ﬂoor.
ZDT uses "Mechanical Health", "Process Health", "System Health" and"Maintenance Health" to eliminate downtime.

Optimal maintenance is achievedby analyzing the life of
consumable components
based on actual robot
operating conditions.

Robot status can be monitored
anywhere using a web browser on a
PC or smart device. Advance

Degradation Status

Mechanical Health
Abnormalities for mechanical parts,
such as reducers, are detected andnotiﬁed several weeks before
actual failure. Therefore,
maintenance can bebetter planned.

System Health

It is possible to collect andvisualize machine process dataand achieve early detection ofequipment abnormalities.

More appropreate actions are
performed by knowing theinformation and status required formaintenance, such as robot

Servo Gun Diagnosis

Controller Memory Status

Maintenance ReminderThis function diagnoses thedeterioration of the reducer oneach axis. A notiﬁcation will besent when the degradation
exceeds the threshold, so robot
failure can be predicted inadvance.

This function diagnoses
servo gun abnormalities.
A notiﬁcation is sent when
the disturbance torqueexceeds the threshold, so
downtime due to servo gun
failure can be prevented.

This function calculates and displays
a summary of the free memory spaceon the controller.
It sends a notiﬁcation if free memory
goes below a pre-determinedthreshold, preventing unexpected
downtime due to lack of memory.

This function tracks the status ofrecommended robot maintenanceitems and optimal replacement
time for consumables. In addition
to optimizing maintenance costs,
component life is extended throughproper maintenance timing.
