J1-8 CLOSED allows normal operation.
OPEN disables the control and the motor coasts to a stop.
J1-9 CLOSED operates the motor in the Forward direction (with J1-10 open).
OPEN motor decels to stop (depending on Keypad Stop mode).
J1-10 CLOSED operates the motor in the Reverse direction (with J1-9 open).
OPEN motor decels to stop (depending on Keypad Stop mode).
Note: Closing both J1-9 and J1-10 at the same time will reset a fault condition.
J1-11 CLOSED selects Analog Input #1.
OPEN selects Level 1 Input block, Command Select parameter.
Note: If Command Select (Level 1 Input block) is set to Potentiometer, then Analog
Input #1 is always selected regardless of this switch position.
J1-12 CLOSED selects STOP/START and Reset commands from terminal strip.
OPEN selects STOP/START and Reset commands from Keypad.
J1-13 CLOSED selects Level 1 Input block, Command Select parameter.
OPEN selects speed commanded from Keypad.
Note: When changing from Terminal Strip to Keypad (J1-12 or J1-13) the motor speed
and direction will remain the same after the change.
J1-14 Selects preset speeds as defined in the Speed Select Table (Table 3-10).
J1-15 Selects preset speeds as defined in the Speed Select Table (Table 3-10).
J1-16 If J1-16 is connected, you must set Level 2 Protection block, External Trip to "ON"
to activate the opto input.
CLOSED allows normal operation.
OPEN causes an external trip fault. The control will disable and the motor coasts
to a stop. An external trip fault is displayed (also logged in the fault log).
