CX-Drive: Setting acceleration duration

[Lux 0]

In CX-Drive there are options to set the acceleration and/or the deceleration time when doing test runs, however these are greyed out for me and I don't know why. I assume there are some parameters somewhere that need to be set but I don't know what those are, and I have tried many parameter combinations but still no joy. The attached image shows the options I cannot select. My setup is: CX-Drive version 1.40.3.14(014) Operating system: Windows XP sp3 Driver: R7D-AP02H Motor: R7M-A20030H The computer is connected to the driver via a R7A-CCA002P2 cable. Any ideas why these options are greyed out?
