SIMOVERT MASTERDRIVES
The blocks must always be configured so they have the shortest
possible interrogation time (< 5 ms). If too slow an interrogation time is
chosen, setpoint jumps or uneven running of the axis may occur.
Preferably, the interrogation time should be the same as that used for
technology option F01 (interrogation time T4).

Setpoint transfer input
The effective setpoints, such as position setpoint [LU], speed [%],
acceleration [%] and deceleration [%], and the binary signals for type of
positioning (absolute or relative) and for direction selection (forwards or
backwards) all form part of the "set setpoint" transfer.
The speed, acceleration and deceleration setpoints are percentage
values that must always be positive (negative setpoints are limited to
0 %).
