given below.
Installation Orientation and Space for
Σ
-V-SD Driver
• Always install the power regeneration converter on the left side of the SERVOPACK.
• We recommend that you install the SERVOPACKs in order of capacity, with the SERVOPACK with the
largest capacity closest to the power regeneration converter.
• All of the
Σ
-V-SD drivers have external heat sinks for cooling.
• Refer to the external dimension diagrams for external dimensions and mounting dimensions of the products
(
4.1.2 External Dimensions
and
4.2.2 External Dimensions
).
• Make sure that the ambient air temperature of the
Σ
-V-SD driver is 0 to 55
°
C near the heat sink and inside
the control panel at a 70% load, and 0 to 40
°
C inside the control panel at a 100% load.
• To prevent oil penetration, seal the mounting screw sections of the power regeneration converter and the
SERVOPACK.
• Always install the
Σ
-V-SD driver with the fan at the top to ensure efficient cooling.
• When mounting the
Σ
-V-SD driver, allow space above and below it to prevent heat buildup.
• When stirring the air inside the control panel, do not allow the airflow to fall directly on the
Σ
-V-SD driver
to prevent dirt from collecting on the
Σ
-V-SD driver.
• Provide the following spaces between the units.
