Use P46 – [Input Mode] to select the control
method for start, stop, and direction control.
There are four settings from which to choose:
D Setting 0 – three wire control (this is the
factory default setting).
D Setting 1 – two wire “run forward/run
reverse”control. Note: The “run” inputs must
be maintained.
D Setting 2 – program keypad module control.
See page 3–1.
D Setting 3 – momentary “run forward/run
reverse” control. Note: The “run” inputs do
not need to be maintained.

Control Wiring (continued)
 Do not exceed control wiring length of 15 meters (50
feet). Control signal cable length is highly dependent
on electrical environment and installation practices.
To improve noise immunity the control terminal block
common must be connected to earth ground.
Consult factory for longer control signal cable length
applications.

ATTENTION: The program keypad
module stop key simulates momentary
pushbutton operation. For “two wire”
control schemes (P46 – [Input Mode],
setting “1”) the program keypad module
stop button will only provide a “stop”
function while the stop key is depressed.
ATTENTION: When changing the
parameter setting for P46 – [Input
Mode], you must cycle power for the
change to take effect.
