5.4. CN4 : Motor Cable Connector
l Since the Motor cable supplied with the Megatorque Motor System should always be used, you
need only plug the Motor cable connector into CN4. Knowledge of the pin assignment or signal
name is not necessary. This section is offered for reference.
Caution : • Do not change the cable length.
• Do not use other connector between the Motor cable and CN4.
Danger : • Be careful for orientation of the connector when inserting it. The connector is
a self-lock type. Insert the connector to its bottom, otherwise it will not lock.
• Never insert/remove the CN4 connector with the Driver Unit power turned
on.
• A high voltage is applied to this connector after the power is turned on. Be
very careful not to cause short-circuit.
