• One to three parameter values

– The default display shows

parameters 0103 (OUTPUT

– Use parameters 3401, 3408, and 3415, see page 34,

to select the parameters (from Group 01) to display.

Entering “parameter” 0100 results in no parameter

=0100,thenonlytheparameterspeciedby3408

appears in the Control Panel display.

– You can also scale each parameter in the display, for

example, to convert the motor speed to a display of

conveyor speed. Parameters 3402…3405 scale the

parameterspeciedby3401,parameters3409…3412

scaletheparameterspeciedby3408,etc.
