Programming Parameters C-53
Name: Enable_Brake_Sol Data Type: Bit Flag R, Link
Parameter No.
528
File:
I/O Interface
Group:
Event Links Description: The 8720MC digital I/O can be linked to events within the drive. One of the 8720MC relay contact
outputs can be linked to parameter 528. Parameter 528 is true whenever the drive is enabled and the brake delay
constants (parameters 206 and 207) are satisfied. Entering 528 into digital outputs 2, 3, or 4 will link the “Enable
Brake Solenoid” event to one of the relay contact outputs.

File:
I/O Interface
Group:
Event Links Description: Parameter 529 can be linked to a digital output and is provided in the SCANport logic status word. It
is used to identify when the 8720MC is capable of following the auto reference from the primary source identified
in parameter 501. If the drive enable input is true and the auto mode of operation is active and there are no drive
faults, parameter 565 will be true.

530
File:
I/O Interface
Group:
Event Links Description: Parameter 530 can be linked to a digital output and is used by the system to indicate that the
manual mode of operation is selected. The manual mode of operation can be established from the HIM by
depressing the stop button. It can also be requested from the digital I/O and the SCANport command word. When
parameter 530 is true manual mode is selected. In manual mode the drive can be jogged by the HIM, the digital
I/O or SCANport at the jog reference speed established by the requesting device. When switching from manual
mode back to auto it is necessary to auto enable the drive by dropping the drive enable input low and returning it
back to the true (+24V dc) state. This prevents an auto ref start when selecting auto mode.
