NOTE
By default, if the enable signal is present the drive will not Enable until the button is pressed. To automatically enable the
drive when the enable signal is present set P2-19 = 2 or 3. This then disables the use of the & STOP buttons
In keypad mode, the speed can be adjusted using the & keys on the built in keypad, or a remote mounted Optiport Plus
keypad, in addition to pushbuttons connected to the digital inputs
The reverse input only functions under the following conditions :-
P1-12 = 1, P2-19 = 2 or 3. P2-35 must not be 2 or 3
P1-12 = 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 P1-12 =2, the direction of motor can be reversed by
pressing the button
Closing the reverse input (When using a setting of P2-01 that inlcuides 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.
