Analog Output (cont’d)
Offset
Analog Offset is the analog signal level that will be output when the encoder is at zero
RPM. This allows the minimum analog signal to be greater than zero volts or 4 mA.
Because the analog output module has 4096 increments (12 bits) of signal level avail-
able, the offset is specified as the number of increments of signal that should be output
at zero RPM. Calculate Analog Offset values as follows:
For 0-10 VDC: (Minimum Signal/10) x 4096
Example: For a 2 VDC minimum signal; Offset = (2/10) x 4096 = 819
For 4-20 mA: ((Minimum Signal - 4)/16) x 4096
Example: For a 5 mA minimum signal; Offset = ((5-4)/16) x 4096 = 256

Purpose
This screen displays the number of analog outputs that will be programmed into the
controller.
The controller can have one or two analog outputs, and each can be offset and scaled
by different values. See ANALOG OUTPUT for details.
Programming
Use the numeric keys to enter “1” or “2” analog channels. An analog output module is
required to generate an analog output signal.
