3402 SIGNAL1 MIN -

Defines the minimum expected value for the first display parameter.

• Use parameters 3402, 3403, 3406, and 3407, for example to convert

a group 01 parameter, such as 0102

SPEED (in rpm) to the speed of a

conveyor driven by the motor (in ft/min). For such a conversion, the

source values in the figure are the min. and max. motor speed, and

the display values are the corresponding min. and max. conveyor

speed.

Note: Selecting units does not convert values. Parameter is not

effective if parameter 3404

OUTPUT1 DSP FORM = 9 (DIRECT).
