PowerPak Power Fault Manager
The Brooks Automation MagnaTran 7 PowerPak provides power allowing a con-
trolled shutdown of the robot during loss of +24V power.
The PowerPak does not require any hardware to replace. The PowerPak mounts
directly to the MagnaTran 7 drive while access to the robot I/O panel remains.
Operation
Upon loss of primary power, the PowerPak will supply a maximum of 20A for 2 sec-
onds and signal the robot to start a controlled shutdown. After two seconds, the Pow-
erPak removes battery power from the robot.
The following timing sequence is
initiated in these instances:
•
When +24VDC power is less than +22VDC, the Power Pack is switched on.
•
When +24VDC power is less than +22VDC and lasts more that 50mS, the
Power Pack is switched on and AC_FAIL_UPS is asserted.
•
When +24VDC power is less than +22VDC and lasts more that 2 seconds, the
Power Pack is switched on, AC_FAIL_UPS is asserted and at the end of 2 sec-
onds, power is removed from the robot.
