See recommended terminal
tightening torques in Section 6.
J4-8 CLOSED allows normal control operation.
OPEN disables the control and motor coasts to a stop.
J4-9 Momentary CLOSED starts motor operation in the Forward direction.
J4-10 Momentary CLOSED starts motor operation in the Reverse direction.
Note: Closing both J4-9 and J4-10 at the same time will reset a fault condition.
J4-11 Momentary OPEN motor decels to stop (depending on Keypad Stop mode).
J4-12 CLOSED selects the Level 1, Input, Command Select parameter value.
OPEN selects EPOT.
J4-13 CLOSED selects ACC / DEC / S-CURVE group 2.
OPEN selects ACC / DEC / S-CURVE group 1.
J4-14 Momentary CLOSED increases motor speed while contact is closed.
J4-15 Momentary CLOSED decreases motor speed while contact is closed.
J4-16 If J4-16 is connected, you must set Level 2 Protection block, External Trip to
“ON” to activate the opto input.
CLOSED allows normal control operation.
OPEN causes an external trip fault. The control will disable and the motor
