REMARKS
 When a parameter is set as the acceleration/deceleration time (0.1s), the 0.01s increment is dropped.
 When a parameter is set as the acceleration/deceleration time (0.01s), the parameters are limited at the maximum
value of the parameter setting range. For example, Pr.7 = "361.0s" when 0.1s increment is selected, and Pr.7 =
"360.00s" when 0.01s increment is selected.
