8.2 WARNING PARAMETERS
The warning parameters are displayed in the Status page to indicate that a particular condition is taking
place, although the drive is not locked.
Those parameters are marked by a W followed by the parameter number.
8.2.1 W002: SPEED FEEDBACK LOSS
W002 - Speed Fdbk switched to Varm
The drive has switched from tacho or enP/Nr feedback to armature feedback.
When the run contacts open, the warning disappears and the equipment
restores the prior feedback type.
8.2.2 W003: HARDWARE LIMIT CURRENT NOT AT MAXIMUM VALUE
Should the display show warning message W003 (Imax [T2] <100%), trimmer
T2 of the control board has NOT been completely rotated clockwise. The
trimmer indicates a hardware limitation of the armature current, which is also a
wrong position. In fact, it would cause a disagreement between the preset
current limit values (shown by the display) and the maximum armature current to
be obtained. Then, the latter value would be lower than that required.
In this case it is necessary to turn trimmer T2 completely clockwise. Then, the
warning disappears. Trimmer T2 is located on the right side of the control
board, near the two 7-segment displays which can be seen through the small
slot on the drive cover. The trimmer should be used by the Service personnel
only, to temporarily reduce all the current limits during special test performances.
After that, it should be reset to its maximum position.
8.2.3 W004: SAFE RESTART AFTER AN ALARM RESET
W004 - Open-Close ENABLE to run
If par. C094 (StartSafety) is set to 1:Yes and an alarm tripped has been manually
or automatically reset, this warning indicates the steps to take for the drive
restart. This warning disappears when the ENABLE input opens.
8.2.4 W005: RESTART AFTER AN EMERGENCY STOP FROM KEYPAD
W005 - Open-Close START to run
If the equipment has been stopped by pressing the “STOP” key on the keypad
(par. C103 (EmergStop) set on purpose), this warning indicates the steps to take
for the drive restart. This warning disappears when the START input opens.
