Function Checks Step 12 -- Drive Supplied Contact Settings Check
- Motor Disconnected
Stop the drive. Remove and lock out all incoming power to the drive, then
remove the drive cover.
Reapply power and start the drive. N.O. contact CR2 (terms. 20 & 21 on
the Control and Signal Wiring Terminal Block) will close as presently
programmed by Parameter 23. Once the drive is within
±
2 Hz of set speed,
N.O. contact CR1 (terminals 19 & 20 on the Control and Signal Wiring
Terminal Block) will close since Parameter 24 is presently set to 1.
Step 13a -- Auto Restart Settings Check
!
ATTENTION: Auto restart operation may only be used as
outlined in NFPA79, Paragraph 6-14 (exceptions 1-3) for
specialized applications. Equipment damage and/or personal injury
may result if the settings of Parameters 47-49 are used in an
inappropriate application.
To properly program the drive to restart when required demands that
Parameters 47-49 be coordinated correctly. When Parameter 48 is set to 1
or 2, it will override any setting made in Parameter 47. Likewise the restart
time set in Parameter 49 will affect the restart actions taken by both
Parameters 47 and 48.
Step 13b -- Auto Restart Settings Check
If Power Loss Restart is required, set Parameters 1 and 3.
Stop the drive.
•
Change Parameter 47 from 1 to 3.
•
Change Parameter 49 from 000.1 seconds to 10.00 seconds.
Press the start pushbutton. The directional start pushbutton LED will
immediately light. After 10 seconds the drive will ramp up to 60 Hz and
the main display will show
60.00
.
Remove then reapply incoming power to the drive at the disconnect device
within 100 ms.
LU
will be shown at the main display indicating a power
fault. Press the stop pushbutton to clear the fault, then the start pusbutton to
start the drive. Since Parameter 49 has been changed, the drive will not
restart for 10 seconds.
•
Had the drive been configured for 2-wire control and Parameter 47 set to
0, without clearing the fault, the drive would have automatically
restarted and ramped up to 60 Hz without a waiting time.
•
Had the drive been configured for 2-wire control and Parameter 47 set to
3, without clearing the fault, the drive would have automatically
restarted and ramped up to 60 Hz after 10 seconds.
