3-3 Location and installation
3-3-1 Environment of location
The environmental conditions of the location for RSF supermini series actuators must be as follows.
◆
Service temperature: 0
°
C to 40
°
C
When the actuator is installed in a closed space, the temperature in the
space may be higher than the atmosphere because of heat emission by the
actuator. Design the closed space size, ventilation system, and device
locations so the ambient temperature near the actuator is always less than
40
°
C.
◆
Service humidity:
20 to 80% relative humidity, without condensation
Make sure no water condensation occurs at the place where there is a large
temperature change in a day or due to frequent heat-and-cool cycles due to
the operation of the actuator.
◆
Vibration:
less than 49m/sec
2
(10Hz~400Hz)
◆
Impact:
less than 300 m/sec
2
◆
Make sure the actuator is in an area free from: dust, water condensation, metal powder, corrosive
gas, water, water drops, and oil mist.
◆
Locate the driver indoors. Do not expose it to the sunlight.
3-3-2 Considerations into External Noise
Pay sufficient attention when installing the actuator: The actuator may malfunction by external noise
depending on the conditions of installation.
u
Make sure that the FG line of RSF-5B is securely grounded.
u
Because RSF-3C does not have any FG line from the motor enclosure. Thus, when using it,
make sure that that enclosure is securely grounded to the body of the equipment through the gear
head house. In addition, make sure that the body of the equipment is securely grounded.
u
Do not bind the motor line and encoder signal line together.
u
Do not draw any external power line (i.e., driver power supply line, 100/200 VAC line.), actuator
signal line, and motor line through the same pipe or duct or bind them together.
The noise tolerance values of RSF supermini equipment are listed below.
They are guide values from a measurement that were performed using a standard relay cable in a
noise test environment while the clamp filter included with the product was installed to the equipment..
Note that the noise tolerance values in your actual environment of use may differ from them.
