7-2 Installation of the servo amplifier
CAUTION
1. Always observe the installation directions. Failure to observe this could lead to
faults.
2. Secure the specified distance between the servo amplifier and control
panel, or between the servo amplifier and other devices. Failure to observe
this could lead to faults.
3. Do not let conductive objects such as screws or metal chips, etc., or
combustible materials such as oil enter the servo amplifier or servomotor.
4. Do not block the servo amplifier intake and outtake ports. Doing so could
lead to failure.
7-2-1 Environmental conditions
Environment Conditions
Ambient temperature
0°C to +55°C (with no freezing)
Ambient humidity 90% (RH) or less (with no dew condensation)
Storage temperature
–15°C to +70°C (with no freezing)
Storage humidity 90% (RH) or less (with no dew condensation)
Atmosphere Indoors (Where unit is not subject to direct sunlight)
With no corrosive gas, combustible gas, oil mist or dust
Altitude 1000m or less above sea level
Vibration 5.9m/s
2
or less
CAUTION
1. The ambient temperature condition for the servo amplifier is 55°C or less.
Because heat can easily accumulate in the upper portion of the amplifier,
give sufficient consideration to heat dissipation when designing the power
distribution panel. If required, install a fan in the power distribution panel to
agitate the heat in the upper portion of the amplifier.
2. If a servo amplifier fault should occur, turn OFF the power on the servo
amplifier's power supply side.
3. Shut off the power with the error signal. Failure to do so could cause the
regenerative resistor to abnormally overheat and fires to occur due to faults
in the regenerative transistor, etc.
4. Always install the MDS-B-CV-370 external contactor. Do not use the
external contactor with other CV power supply units. Failure to observe this
could lead to damage.
5. The MDS-B-V14L-110/150 do not have built-in dynamic brakes. Always use
the external dynamic brake unit.
