This will usually be at the end of a hard acceleration when both the torque and speed of the
motor is high.
Environment
To ensure proper operation of an AZ servo drive, it is important to evaluate the operating
environment prior to installing the drive.

Ambient Temperature Range and Thermal Data
AZ drives contain a built‐in over‐
temperature disabling feature if the baseplate temperature rises above 75
º
C. For a specific
output current, the graphs below specify an upper limit to the ambient temperature range AZ
drives can operate within while keeping the baseplate temperature below 75
º
C. It is
recommended to mount the baseplate of the AZ drive to a heatsink for best thermal
management results. For mounting instructions and diagrams see
“Mounting” on page 23
.
1.
The heatsink used in the above tests is a 15" x 22" x 0.65" aluminum plate.
Shock/Vibrations
While AZ drives are designed to withstand a high degree of mechanical shock
and vibration, too much physical abuse can cause erratic behavior, or cause the drive to cease
operation entirely. Be sure the drive is securely mounted in the system to reduce the shock and
vibration the drive will be exposed to. The best way to secure the drive against mechanical
vibration is to use screws to mount the AZ drive against its baseplate. For information on
mounting options and procedures, see
“Mounting” on page 23.
Care should be taken to ensure the drive is securely mounted in a
location where no moving parts will come in contact with the drive.
