Maintenance
Before beginning work
In most cases, maintenance should be performed with the main power turned off.
However, some maintenance tasks are performed under emergency stop conditions with the power turned on.
In such cases, ensure adequate safety and press the emergency stop before beginning the maintenance.
The power is turned on during maintenance where any servo-axis must be operated or YSi-V operation
checked. In this case, also ensure adequate safety before beginning the maintenance.
When operating the YSi-V, make sure the following conditions are met.
n
Operating conditions
1. Supply air pressure is kept at correct pressure.
2. All safety covers are closed.
3. Power cable is correctly connected.

Maintenance
1. Maintaining YSi-V performance
The most important condition essential for maintaining the performance of the YSi-V you purchased is using
it under good environmental conditions. Performing daily maintenance and periodic inspections is also
absolutely essential.

NOTE
When using an industrial humidifier as static electricity prevention measures, be sure to refer "1.3 Importance of
appropriate humidity management", and comply it.

Maintenance
1.2 Importance of periodic inspections and cleaning
Periodic inspections and cleaning are extremely important maintenance tasks. Failure to perform inspections
and cleaning will prevent the YSi-V from delivering full performance and may lead to inspection errors or YSi-V
breakdowns.
Examples:
• Dirty optical system (camera, lighting, etc.) may cause recognition errors.
• Poor greasing of axes may cause abnormal noises.
• Poor inspections such as of valves may cause errors in PCB clamping and conveying.
As these examples show, failure to make inspections may lead to YSi-V problems. We strongly recommend you
perform periodic inspections and cleaning to ensure the YSi-V is used under optimal conditions.
1.3 Importance of appropriate humidity management
The inappropriate humidity management of the machine installed floor, it triggers dew drops and may damage
the control circuit inside of machine.
Perform the following itmes to secure machine endurance.
n
Check the temperature and humidity of your site before turning on machines.
• Actuate the air conditioner, humidifier or dehumidifier to adjust the temperature and humidity matched to the
environmental condition described in "1.1 Essential conditions and working environment", confirm the temperature
and humidity of your site settle and then turn on machines.
n
Use the humidifier adequetly.
• Use the water without much impurity for humidifier.
• The spray type humidifier should be installed at high place enough from machines. Adjust the amount of mist to
prevent the dew drops on machine surface.
• Adjust the humidifier operation as necessary. Especially the using of humidifier in humid period, the humidity may
excess 80%.
TIP
The water without much impurity refers to that is filtered by the dedicated equipment.
The impurity amount of filtered water can be perceived by the electrical conductivity of water (S/cm);
General tap water in Japan: 100 - 400 μS/cm
Filtered tap water: approx. 1 - 2 μS/cm
c
CAUTION
For your humidifier, DO NOT use tap water or well water. Those water include small amount of elements as such
Natrium or Chlorine, may cause a decline of insulation, and it may damage the circuit inside of machine.
