Applied Motion PDO2035 - Manual (Page 14)

Mounting the Drive
You should mount the PDO 2035 on the heat transfer plate as shown below. Use #8
or #10 screws.
The amplifiers in the drive generate heat. Unless you are running at 1 amp or
below, you may need a heat sink. To operate the PDO 2035 continuously at maximum
power you must properly mount it on a heat sinking surface with a thermal constant
of no more than 4
°
C/watt. Often, the metal chassis or enclosure of your system will
work as an effective heat sink.
