Drive Heatsink Plate Installation Screw Size and Tightening Torque (Finless Drive)
Screw size and torque specifications for heatsink plate installation screws that hold the drive to a metal back panel are
listed in
.
Table 2.11 Screw Size and Tightening Torque
NOTICE:
Tighten all screws according to specified torques. Failure to do so may inhibit drive cooling and possible damage the drive.
◆
Heatsink Plate Temperature (Finless Drive)
The aluminum panel on the back of the drive is referred to as the “heatsink plate.” The heatsink plate temperature should
never exceed the following values:
CIMR-TCBV
, CIMR-TC2V0001 to 0020, CIMR-TC4V0001 to 0011: 90
°
C
CIMR-TC2V0030 to 0069, CIMR-TC4V0018 to 0038: 80
°
C
Standard replacement time for this product is ten years, provided the following conditions are met.
lists the thermal characteristics of the drive.
Use parameter U4-08 to check the temperature of the heatsink plate as described below.
NOTICE:
The drive may be damaged if the temperature of the heatsink plate exceeds specified tolerance levels (90
°
C or 80
°
C,
depending on the model). Excessive heat can also shorten the performance life of various drive components.

Checking and Monitoring Heatsink Plate Temperature
Checking Heatsink Plate Temperature Using the LED Operator
Scroll to parameter U4-08 (heatsink plate temperature).
When the temperature of the heatsink plate is 89ºC, U4-08 will display:
