5.7 “Cyclic Synchronous Torque (CST)” operating mode
In this mode, the drive receives the torque target at fixed time intervals (cycles) from
the control. In this case, the drive no longer calculates ramps but only transfers the
target values directly to the torque or current controller.
In this operating mode the limit switches on the digital inputs 2
0
and 2
1
are ignored.
The target torque is transferred cyclically via PDO by means of the object 0x6071, to
which the drive responds immediately. Bit 4 in the control word does not have to be
set.
