Digital Outputs Description: The standard 8720MC has 10 digital inputs and 10 digital outputs. Parameter 661 provides a means
of monitoring the status of the 10 digital outputs. The status of each of the 10 outputs appears in one of the bits (0
to 9) in the Output Image word. The output status can be displayed on the HIM or DriveExplorer
via SCANport as a
bit pattern.
Structure of the digital output word:
Bit 0 = Digital Output 1
Bit 1 = Digital Output 2
Bit 2 = Digital Output 3
Bit 3 = Digital Output 4
Bit 4 = Digital Output 5
Bit 5 = Digital Output 6
Bit 6 = Digital Output 7
Bit 7 = Digital Output 8
Bit 8 = Digital Output 9
Bit 9 = Digital Output 10

Group:
Digital Outputs Description: Parameters 662 to 671 contain the linkable parameter number for the 8720MC digital outputs. For
example if it is desired to support an output that indicates that the 8720SM motor high winding output is enabled,
via digital relay contact output 3, then this can be accomplished by entering parameter number 526,
“Hi_Wind_Enable” into parameter 664. Entry can be made via the HIM or DriveExplorer.
Parameter 610,
“Drive_OK”, is permanently assigned to parameter 662. All other outputs have default assignments based on the
application as determined by parameter 501. Parameters 663 to 671 can be modified by the user if the default
settings are not appropriate for the intended application. For the 8720MC outputs 1 to 4 are relay contacts while 5
to 10 are solid state 24vdc drivers.

Analog Outputs Description: The 8720MC Drive supports two +/-11 bit analog outputs. Parameter 681 provides a means of
linking the 8720MC physical address of: connector P4, row 1, terminal 1 and row 2, terminal 6 (analog output 1)
to a variable within the drive. This allows the user to link an external analog output to a linkable variable within
the 8720MC Drive. A +/- 10V dc analog voltage can be provided at analog output 1 which represents the value of
an 8720MC parameter such as % rated torque value or velocity feedback value or % power. Analog output 1,
parameter 681 contains the parameter number of the linked variable. If a +/- 10V dc analog output representing
actual velocity is desired at analog output 1 then parameter number 40, velocity feedback, must be entered into
parameter 681. The analog output value can be modified by multiplying the source variable by the scaling factor
stored in parameter 682.
