Capacitor
・
A smoothing capacitor deteriorates its characteristic under the effect of ripple current. The operating life
of capacitor varies depending on the ambient temperature and using conditions but it lates about 5 years
under the general operating condition.
１２－１－５
Relay
・
Contacts wear due to the open/close current. Relay reaches the life limit by about 100,000 times of operation
１２－１－６
Cooling fan
・ Due to the bearing’s operating life, the cooling fan has the life of 10,000 to 30,000 hours
under continuous operation.
１２－１－７
Battery
・
Battry life is basically about 5 years. But it varies depending on the application to use.
１２－１－８ Ｅ２ＰＲＯＭ
・
E2PROM for parameters storing has the limit of overwriting frequency. Data holding time is about 10 years.
１２－２
Guarantee
The overwriting frequency under the guaranteed condition is as follows as an outline. It is restricted
by the shortest condition in the following terms.
Parameter overwrite
（
Fn01 to Fn12
）
Each 10,000 times/total
Program overwrite 10,000 times/each axis
Tightening history data Tightening of about 10,000,000 times/axis
Engine number data About 59,520,000 units
Alarm history Alarm 10,000 vtimes occurrence/each axis

Tightening operation glossary
UNIIT
：
Multiple axes control up to 30 axes can be treated as each axis to independently operate
or as a group of several axes (a unit) to operate together. One interface unit can control the maximum 7 units.
At least one controller belongs to one unit (maximum 30 axes control to one unit),
and one input command is assigned to one unit and then all belonging axes start operation simultaneously.
In SIO, different station numbers assigned to each unit.
PROGRAM
：
Screw tightening program can form the program from 1 to 24 on each axis.
One program begins with the control flag(Zero magnification check is performed or not, etc.) and rating setting,
and it is possible to set operation to maximum 77 steps.
However, the rating block number, screw number and end is handled as 1 step.
At least one block should have been set in the program.
