Voltage Ripple Warning Bit 3
The Voltage Ripple Warning bit is set if the
ripple on the DC bus exceeds the voltage
ripple threshold value stored in local tunable
VRT_E0%. Hex Value: 0008H
Sug. Var. Name: WRN_VR@
Access: Read only
UDC Error Code: N/A
LED: N/A
This bit is intended to be used to detect an input phase loss if three-phase AC input
is used, but it can also be used for a common bus supply.
Reference In Limit Warning Bit 4
In Vector mode, the Reference in Limit
Warning bit is set if the reference to the
regulator exceeds the maximum value
permitted (+/- 4095) or is being limited by
the system in response to an overvoltage or
undervoltage warning. Hex Value: 0010H
Sug. Var. Name: WRN_RIL@
Access: Read only
UDC Error Code: N/A
LED: N/A
In Volts per Hertz mode, this bit is set if current limit is selected and the regulator
has detected a specified current output within a specified time limit. The regulator
will begin adjusting output frequency to limit current.
This bit is also used by the bridge test to indicate an illegal test code. Refer to the
SA3100 Drive Configuration and Programming instruction manual (S-3056) for
additional information on the bridge test.
Tuning Aborted Warning Bit 5
The Tuning Aborted Warning bit is set if any
of the automatic tuning procedures (e.g.,
resolver balance and gain calibration) is not
successful. Hex Value: 0020H
Sug. Var. Name: WRN_TUN@
Access: Read only
UDC Error Code: N/A
LED: N/A
Over Temperature Warning Bit 7
The Over Temperature Warning bit is set if
the Power Module’s heatsink reaches a
temperature of 90° C. Hex Value: 0080H
Sug. Var. Name: WRN_OT@

UDC Error Code: N/A
LED: N/A
