Operation sequence
1) Starting with point table No. 1
2) Varying the speed and executing point table No. 2
3) Varying the speed and executing point table No. 3
4) Executing point table No. 1 used at start-up in CW direction when "8" is set to the auxiliary
function of point table No. 3
5) Repeating the above execution in the sequence of 1), 2), 3), 4), 2), 3), 4)
