Parameter Description
Teach Mode This parameter is only important when your application provides a
combination of the two inputs (e.g. A + B). The setting determines how to
scale the total result of the selected A/B calculation
Teach Mode = 0: The unit will automatically calculate a new "full scale"
Teach Mode = 1: The total result will use the same scaling as applied to
Teach Mode = 2: Before calculating the combination result, the channel B
Analog Mode: Determines which Analog output format should be used (see 5.3):

Output Mode = 0
-10V ... 0 ... +10V
Analog Offset: Parameter to shift the zero position of the Analog output over the full range
of +/- 9999 mV resp. +/-19,998 mA (if applicable). Normal setting is 0.
Analog Gain: Allows setting the maximum swing of the Analog output.
Setting 1000 results in a full scale signal of 10 volts or 20 mA,
setting 500 will reduce the signal to 5 volts etc.
*) Example: Provided you have set both inputs A and B to a range of 0 ... 10 kHz for a 0 ... 10 volts
output, and after this you switch over to the sum mode A + B:
Teach Mode = 0 would allow to apply the full frequency range of 10 kHz to each of the inputs at the
same time, because the automatic re-scaling function has set a full range scale of 20 kHz for the
expected maximum of the sum A + B.
Teach Mode = 1 would reach the full-scale output already with a sum of A + B = 10 kHz, because only
the 10 kHz / 10 volts scaling of input A will apply

frequency will be pre-scaled using the conversion
parameters „Multiplier" and „Divisor" , so that a direct
compare between two frequencies of different scaling
can take place.
