*
*Note: Remove factory jumper from J2-8 and J3-24 before connecting switch at J2-8.
J2-8 CLOSED allows normal control operation.
OPEN disables the control and the motor coasts to a stop.
J2-9 MOMENTARY CLOSED starts motor operation in the Forward direction.
J2-10 MOMENTARY CLOSED starts motor operation in the Reverse direction.
Note: Closing both J2-9 and J2-10 at the same time will reset a fault.
J2-11 MOMENTARY OPEN motor decels to stop.
J2-12 CLOSED selects Level 1 Command Source parameter value.
OPEN selects E-POT.
J2-13 CLOSED selects ACC / DEC / S-ACC /S-DEC group 2.
OPEN selects ACC / DEC / S-ACC /S-DEC group 1.
J2-14 MOMENTARY CLOSED increases motor speed while contact is closed.
J2-15 MOMENTARY CLOSED decreases motor speed while contact is closed.
J2-16 Optional External Trip input (not required). If used, you must set Level 2 Drive Protect block, External Trip to “ON”.
CLOSED allows normal operation.
OPEN causes an External Trip to be received by the control (when programmed to “ON”).
