you can choose whether the slave is to run at a fixed
speed set in par. 19-03 or whether it is to maintain current speed. For the duration of the Hold

this having any effect on the slave drive. While the Hold function is activated you can change the
speed with inputs 32 and 33. The speed is changing according to the settings in par. 19-04
