C-60 Programming Parameters
Name: Drive_Ok Data Type: Bit Flag R, Link
Parameter No.
610
File:
I/O Interface
Group:
Event Links Description: The 8720MC drive parameter 610 “Drive OK” is permanently linked to digital output 1, Parameter
661, the drive OK output relay contact. This is provided as a motion controller output to indicate that there are no
major faults and that the drive can be enabled.

Name: Shut_Down_Error Data Display: Bit Flag R/Link
Parameter No.
615
File:
I/O Interface
Group:
Event Links Description: The 8720MC drive parameter 11 defines 14 different types of shut down errors which can occur.
Parameter 615 becomes true if any of these shut down errors occur. Parameter 615 remains true until the fault is
removed and its is cleared by the Drive Error Reset input or the SERCOS master. Parameter 615 can be linked to
a digital output by writing its parameter number into an output source word. In so doing if a shut down error
occurs the digital output will become true.

Name: Power_Supply_OK Data Type: Bit Flag R/link
Parameter No.
617
File:
I/O Interface
Group:
Event Links Description: The standard 8720MC-RPS has a regenerative power supply fault relay contact output. If this fault is
connected to terminal P5-36, Digital Input 10, an interlock to “Power Supply OK” is created. When 8720MC-RPS
Fault contact is closed an RPS fault condition does not exist. Therefore, a high input to the 8720MC digital I/O is
interpreted as “Power Supply OK” when it is linked to parameter 617. If the 8720MC digital input goes low,
“Power Supply OK” will become false and an 8720MC shut down error (parameter 11, bit 9) will occur. After the
fault is removed a Drive Error Reset is necessary to clear this error. Parameter 617 can be linked to an digital
output.
