Drive Warning Register B-3
Bad Gain Data Warning Bit 8
The Bad Gain Data Warning bit is set if any
of the following conditions is detected: Hex Value: 0100H
Sug. Var. Name: WRN_BGD@
Access: Read only
UDC Error Code: N/A
LED: N/A
• A current minor loop gain variable or a vector algorithm variable has been
modified by the user outside of acceptable limits. The invalid value will be ignored
by the system and the last acceptable value entered will be used. For a
description of the tunable variables, refer to Appendix B.
• Drive parameter(s) have been loaded that are outside of acceptable limits. This is
also part of an interlock test that will prevent the drive from entering the run mode.
See register 205/1205, bit 0.
• The following relationship between the power loss fault threshold (PLT_E0%), the
overvoltage warning threshold (OVT_E0%), and the undervoltage warning
threshold (UVT_E0%) is not true: PLT_E0% < UVT_E0% < OVT_E0%.
• OVT_E0% > 975V for 575 VAC Power Modules,
> 800V for 460 VAC Power Modules,
> 400V for 230 VAC Power Modules.
Thermistor Open Circuit Warning Bit 9
The Thermistor Open Circuit Warning bit is
set if an open is detected in the Power
Module’s thermistor circuit. Hex Value: 0200H
Sug. Var. Name: WRN_TOC@
Access: Read only
UDC Error Code: N/A
LED: N/A
Flex I/O Communication Warning Bit 13
The Flex I/O Communication Warning bit is
set if a Flex I/O communication problem is
detected and logged in registers 10, 11, 22,
or 23. Hex Value: 2000H
Sug. Var. Name: WRN_FLX@
Access: Read only
UDC Error Code: N/A
LED: I/O FLT
Refer to the SA3100 Drive Configuration and Programming instruction manual
(S-3056) for further information.
CCLK Not Synchronized Warning Bit 14
The CCLK Not Synchronized Warning bit is
set if the CCLK counters in the PMI
Regulator and the UDC module are
momentarily not synchronized. Hex Value: 4000H
Sug. Var. Name: WRN_CLK@
Access: Read only
UDC Error Code: N/A
LED: N/A
