8 YASKAWA ELECTRIC TOBP C710606 40A YASKAWA AC Drive - J1000 Finless Installation Manual
3 Conditions of Acceptability
3 Conditions of Acceptability
Adhere to the installation conditions specified in this manual to take full advantage of the
finless design of this drive.
◆ Ambient Temperature
The drive ambient temperature shall not exceed 50 ºC (122 ºF) for the drives installed
location.
◆ Heatsink Plate Temperature
The aluminum panel on the back of the drive is referred to as the “heatsink plate.” The
heatsink plate temperature should never exceed 90 °C
Table 6 and Table 7 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
level (90 °C). 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 89 ºC, U4-08 will display:
Checking Heatsink Plate Temperature Using an Analog Output
Example: When using Multi-Function Analog Output Terminal AM, set the parameters
shown in Table 1.
