Fig. 4−2 Influence of the delay time (C0912)
Switch−off threshold OU
Switch−on threshold OU
The period of time between exceeding the switch−off threshold OU and undershooting the
switch−on threshold OU equals or is higher than the delay time set in C0912.
After undershooting the switch−on threshold OU, the pulse inhibit is deactivated.
The period of time between exceeding the switch−off threshold OU and undershooting the
switch−on threshold OU is lower than the delay time set in C0912.
The pulse inhibit is deactivated after the delay time in C0912 has elapsed.
ƒ The delay time in [ms] is set under C0912. The Lenze setting can be changed by the
factor 0.5 ... 2.
