Pr.5-10 to Pr.5-16 correspond to operation time of each multi-step speed defined by parameters 5-00 to 5-06. The maximum value of these parameters is 65500 sec., and it’s displayed as d65.5.

NOTE

If a parameter is set to “d0” (0 Sec), the corresponding step will be skipped. This is commonly used to reduce number of program steps.
