TS01 NTSD Mode
The NTSD Mode defines the assignment of the NTS inputs to the NTSD speed
thresholds.
The NTSD inputs can be assigned in parameters LI04 - LI11 to the corresponding
hardware inputs X2A1-8, or by FB21-27 to the corresponding serial Control Word special
function bits 9-15.

No function.
Threshold 1*
Single NTSD threshold.
Threshold 2, Binary
Encoded*
Two NTSD thresholds, binary coded from two inputs.
Threshold 3, Binary
Encoded*
Three NTSD thresholds, binary coded from two inputs.
One switch per threshold***
Up to three NTSD thresholds, each assigned to an individual
input.
* If any NTS input is not active at the beginning of a run, the drive will enter normal
acceleration until the programmed NTS threshold speed is reached then slow down to
the NTSD target speed.
*** If any NTS input is not active at the start a NTS Input Failure fault will be triggered.
The following tables indicate the NTSD speed threshold according to the NTSD mode
and input states.
