11. Verify the new rating shown in Port 10, P21 [Effctv I Rating].
Set Port 10, P20 [Recfg Acknowledg] to 1 “Acknowledge” to accept the
reconfiguration.
12. Press the Stop key on the HIM to clear the fault.
P20 [Recfg Acknowledg] automatically returns to 0 “Ready.”
13. Use the HIM download function, DriveExecutive download function, or
DriveExplorer download function to download the parameter settings
saved in Step1.
14. Run the reconfigured drive at the reduced rating and power limits.
Use the Re-Rate Feature to Add or Replace a Drive Assembly
This procedure describes how to use the Re-Rate feature to increase the drive
rating because a drive assembly has been added. For example, a drive assembly has
been repaired and is being reinstalled. Because the drive was Re-Rated when the
drive assembly was removed it needs to be re-rated again to run at full rating and
power limits.
1. Save the drive’s current parameter settings using the Human Interface
Module (HIM), DriveExecutive, or DriveExplorer.
2. Remove all incoming power to the drive.
3. Add the drive assembly to the drive and connect it to the fiber interface
board in consecutive order.
IMPORTANT Drive parameters are set to factory defaults when the new rating is
acknowledged. If a condition exists that does not allow the drive
parameters to be set to factory defaults, setting P20 to 1
“Acknowledge” will not be accepted. Such conditions include the drive
is currently running, DeviceLogix is currently running, or the drive is
communicating with a PLC.
IMPORTANT Do not use the Compare Screen Copy function in DriveExecutive or the
Error Check Download function in DriveExplorer to perform this step.
ATTENTION: To avoid an electric shock hazard, verify that the voltage
on the bus capacitors has discharged completely before servicing.
Measure the DC bus voltage at the DC+ and DC- TESTPOINT sockets on
the front of the power module.
