Digital Inputs Description: The standard 8720MC has 10 digital inputs and 10 digital outputs. Parameter 690 provides a means
of monitoring the digital input status. The status of each of the 10 inputs plus the 2 registration inputs appears in
one of the bits (0 to 11) in the Input Image status word. The input status can be displayed on the HIM or
DriveExplorer via SCANport as a bit pattern.
Structure of the digital output word:
Bit 0 = Digital Input 1
Bit 1 = Digital Input 2
Bit 2 = Digital Input 3
Bit 3 = Digital Input 4
Bit 4 = Digital Input 5
Bit 5 = Digital Input 6
Bit 6 = Digital Input 7
Bit 7 = Digital Input 8
Bit 8 = Digital Input 9
Bit 9 = Digital Input 10
Bit 10 = +24v registration
Bit 11 = +5 v registration

Analog Inputs Description: The 8720MC Drive analog configuration supports two +/-13 bit analog inputs. Analog input 1, the
auto analog reference, is connected to the 8720MC physical address of: connector P1, row 2, terminals 14 and
15. Parameter 691 “AnaInput1_Value” the digital representation of +/- 10V dc analog voltage. Analog Input 1 is
defined in the 8720MC as the analog auto reference command. After scaling, parameter 691 is permanently
linked to parameter 36, the velocity command variable within the 8720MC Drive. This value may be modified by
the scaling factor stored in parameter 695, the analog velocity scale factor. For auto mode, parameter 691 % *
parameter 695 rpm/100% = parameter 36 analog auto velocity reference command in rpm. Parameter 691 is
automatically offset to zero during auto tuning.

Analog Inputs Description: The 8720MC Drive analog configuration supports two +/-13 bit analog inputs. Analog input 2 the
manual analog reference, is connected to the 8720MC physical address of: connector P1, row 2, terminals 16 and
17. Parameter 692 “AnaInput2_Value” stores the digital representation of +/- 10V dc analog voltage. Analog
Input 2 is defined in the 8720MC as the analog manual reference command. Parameter 692 is permanently linked
to parameter 36, the velocity command variable within the 8720MC Drive. This value may be modified by the
scaling factor stored in parameter 696, the manual velocity reference scale factor. For manual mode, parameter
692 % * parameter 696 rpm/100% = parameter 36 analog velocity reference command in rpm.
