It is recommended to use automatic idle-current mode, namely current automatically reduce
to 60% when motor stops, so as to reduce driver heating and motor heating;
It is recommended to mount the driver vertically to maximize heat sink area. Use forced
cooling method to cool the system if necessary.
3. Pin Assignment and Description
The driver has two connectors namely P1 & P2, Connector P1 for control signals connection,
Connector P2 for power and motor connections.
The following tables are brief descriptions of the two
connectors

NOTE
:
FULL CURRENT AND HALF CURRENT CHOICE: (PORT SW 4)
FULL CURRENT:-IF THE DRIVER IS IN FULL CURRENT MODE THIS WILL LEAD TO MOTOR HEAT AND IT WILL ALSO
DAMAGE THE DRIVER.
HALF CURRENT:-THE DRIVER SHOULD ALWAYS BE IN HALF CURRENT MODE AS THIS WILL REDUCE THE HEAT
OF MOTOR AND DRIVER.
