Limit
Master application cycle time
This is the time frame in which the master application generates new setpoints
(e.g. in the position controller cycle).
T
MAPC
Time basis for T
≤ T < T Time of actual-value sensing
I DP
This is the time at which the actual position value is captured before the start of
each cycle.
T = integer multiple of T
I

I_MIN
the drive unit (= 250 µs).
Time of setpoint transfer
O_MIN
This is the time at which the transferred setpoints (speed setpoint) are
DP
accepted by the closed-loop control system after the start of the cycle.
T = integer multiple of T
O
When T
T
O_MIN
the drive unit (= 250 µs).
Data exchange time
DP
This is the time required within one cycle for transferring process data to all
available slaves.

Data_Exchange
This service is used to implement user data exchange between master and
slave 1 - n.
Acyclic service
This service is used to implement user data exchange between master and
slave 1 - n on an acyclical basis.
Reserve: "Active pause" until the isochronous cycle has expired
