Program the SF 500 as follows:
Parameter
P390 = 1
P391-01 = 30
P391-02 = 60
P391-03 = 90
P391-04 = 120
P391-05 = 150
P392-01 = - 10.7
P392-02 = 11. 1
P392-03 = - 5.1
P392-04 = 8.7
P392-05 = -6.0
Note:
Often only one point of compensation is required, usually at a low rate
value. In the prior example, if compensation was only required at 30 t/h, program
the following parameters. Optimize compensation by establishing the next rate
value that agrees with the material test, the compensation is zero and is entered
as the next compensation point.
