Function
Series “HVAC”:
To monitor the drive, the changeover contact of the relay K1 - terminals K11, K12, K14 - can be
assigned with different functions.
C008 = -12-, -13-, -14-:
- The display value(C054) is smoothened with a ring memory with 500 ms.
- The value set under C156 corresponds to a percentage of the rated controller current [I
r
].
- With the control mode “Square characteristic” (C014 = 3), C156 is internally adapted via the field
frequency (C011):
C156
internal
[%] C156 [%]ô
fd 2 [Hz 2 ]
C011 2 [Hz 2 ]
For instance, a belt monitoring can be implemented with this function extension.
Important C156 is only stored in PAR1.
