TS - Terminal Slowdown Data Parameters
TS01
NTSD Mode
264
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 X2A.10 - 18 or by FB21 - 27 to the corresponding serial
Control Word special function bits 9 - 15.
• NTS1 (Normal Terminal Slowdown 1), NUM = 29
• NTS2 (Normal Terminal Slowdown 1), NUM = 30
• NTS3 (Normal Terminal Slowdown 1), NUM = 31

The following tables indicate the NTSD speed threshold according to the NTSD
mode and input states.
*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.
Description:
No function.
Single NTSD threshold.
Two NTSD thresholds, binary coded from
two inputs.
Three NTSD thresholds, binary coded from
two inputs.
Up to three NTSD thresholds, each assigned
to an individual input.
