Power Interface
± 15V interface is the interface to provide power for the motor drive inside the control
box, the voltage is plus or minus 15V (± 15V).
* Table below shows the cable interface definition for ±15V.
DC24V interface is the interface to provide power for the control box internal control
system, and the voltage is DC24V (DC24V).
* The table shows the definition of POWER 2 cable connection.
