How to Program
Example - Reading a parameter value:
Requires a value in par. 3-4 1 Ramp 1 Up Time.
The ma ster sends the following request:
PKE = 1155 Hex - read par. 3-41 Ramp 1 Up Time
IND = 0000 Hex
PWE
HIGH
= 0 000 Hex
PWE
LOW
=0000Hex
If the value in par. 3-41 Ramp 1 Up Time is 10 s,

Conversion:
The various attributes of each parameter are
displayed in section Factory S ettings.Aparameter
value is only transferred as a whole number. Thus,
use a conversion factor to transfer decimals.
E
xample:
Par. 4-12 Motor Speed, Low Limit has a conversion
factor of 0.1. If you wish to preset the minimum
frequency to 10 Hz, transfer the value 100. A
conversion factor of 0.1 means that the value
transferred is multiplied by 0.1. The value
100 is thus perceived as 10.0.
