Functional principle
The limit signal issued depends on:
●
The operating state of the motor
●
The TPF function
●
The parameterized "activity".
Hysteresis for Limit Monitor
You can set the hysteresis for limit monitors here:
Range
0 - 15 % of the threshold value in 1 % increments (5 %)
Note
When using Limit Monitors, always ensure that the correct range and unit are used for the
analog values connected to the limit input. These always have a direct influence on the unit
of the limit value to be set.
Examples of typical units and ranges in SIMOCODE pro:
Unit
Range
Temperatures (e.g. max. temperature)
1 K
0 - 65535
Operating hours
1 s
0 - 1193046
Motor stop time
1 h
0 - 65535
Active power
1 W
0 - 4294967295
Apparent power
1 VA
0 - 4394967295
Timer actual value
100 ms
0 - 65535
Currents (e.g. max. current I_max)
1 % I
e
0 - 66535
Analog Module inputs
-
0 - 27648 (S7-Format)
Thus, for example, a limit value of 473 (K) should be parameterized for a Limit Monitor to
monitor a maximum temperature of 200 °C.
