Program the SF 500 as follows:
Parameter Function
P390 = 1 linearization ON
P391-01 = 30 point 1, rate
P391-02 = 60 point 2, rate
P391-03 = 90 point 3, rate
P391-04 = 120 point 4, rate
P391-05 = 150 point 5, rate
P392-01 = - 10.7 point 1, compensation
P392-02 = 11.1 point 2, compensation
P392-03 = - 5.1 point 3, compensation
P392-04 = 8.7 point 4, compensation
P392-05 = -6.0 point 5, compensation
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.
