2.4 Elimination of Heat
 DM556T reliable working temperature should be < 60℃ (140°F)
 It is recommended to use automatic idle-current mode to reduce motor heating. That means set the SW4 pin of
DIP switch at “OFF” position.
 It is recommended to mount the drive vertically to maximize heat sink area. Use forced cooling method to cool if
necessary.
