External trip input
Open: Forward

Open: Trip
Closed: No Trip
Notes: By default, if the enable signal is present the drive will not Enable until the START button is
pressed. To automatically enable the drive when the enable signal is present set P2-19 = 2 or 3.
This disables the use of the START & STOP buttons.
In keypad mode, the speed can be adjusted using the UP & DOWN keys on the built in keypad, or a
remote mounted keypad, in addition to push buttons connected to the digital inputs.
The reverse input only functions under the following conditions:
- P1-07 = 1, P2-19 = 2 or 3. P2-35 must not be 2 or 3.
- P1-07 = 2. P 2-35 must not be 2 or 3.
The external trip input can be used to connect a motor thermistor by connecting between
terminals 1 and 4
When P1-0 7 = 2 , the direction of motor can be reversed by:
- pressing the START button.
- closing the reverse input (When using a setting of P1-08 that includes this function).
- using a negative speed reference (e.g. select a preset speed of -10Hz).
Since all of these functions can be active at once, care must be taken to ensure the motor always
turns in the correct direction.
