Deutschmann Automation GmbH & Co. KG Configurations ROTARNOCK 100
The evaluation only takes place at the cams’ edges, that means, in case the control detects an
edge (switch on- or switch off edge) the output is always updated whenever the direction of rota-
tion corresponds to the programmed direction.
Example:
set direction for direction cams

In the first cycle after switching on the device and after each program change, all outputs are
updated (independent of the programmed direction), that means, in this cycle the ROTARNOCK
acts like a cam control without direction cams.
Afterwards an update of the outputs only takes place if the encoder’s direction of rotation corre-
sponds to the programmed direction of the output and a cam edge (switch on- or switch off-point)
is present.
In the first cycle after switching on the device, it acts like a cam control
without direction cams!
5.7 Encoder monitoring
A 'genuine' encoder monitoring can be configured for Singleturn-applications. It compares the
encoder value read in each cycle with the value read in before and generates an Error 105 if a
deviation greater than +/- 7 increments has been detected for a period equal to eight times the
cycle time. This procedure reliably detects a defective encoder or a damaged cable, but brief
interference on the encoder line does not result in an error message.
Note:
The most significant encoder track (MSB) cannot be monitored, since the encoder (in case the
MSB is defective) acts as if it would permanently jump back and forth between 0...1/2 encoder
resolution.
Error 100 is not suppressed if the encoder is not connected on units for absolute shaft encoders
with a resolution of 360 or 1,000 increments featuring this option.
