3-32 SA500 Drive Configuration and Programming
Drive Fault Register (Continued) 202/1202
DC Bus Overvoltage Bit 2
The DC Bus Overvoltage bit is set if the DC
bus voltage exceeds 400 VDC. Hex Value: 0004H
Sug. Var. Name: FLT_OV@
Access: Read only
UDC Error Code: 1018
LED:
P.M. FLT
Vcc Power Supply Undervoltage Bit 3
The Vcc Power Supply Undervoltage bit is
set if the input to the +5V supply for the PMI
drops below the necessary voltage to
maintain regulation. Hex Value: 0008H
Sug. Var. Name: FLT_VCC@
Access: Read only
UDC Error Code: 1019
LED:
P.M. FLT
Position Following Error Bit 4
The Position Following Error bit is set if the
maximum position error exceeds the value
set in the PMI Tach Loss Maximum Position
Error register (register 166/1166). Hex Value: 0010H
Sug. Var. Name: FLT_POS@
Access: Read only
UDC Error Code: N/A
LED:
N/A
This may be due to a loss of tachometer feedback or undesirable motor response in
the position loop.
Velocity Error Exceeded Bit 5
The Velocity Error Exceeded bit is set if the
maximum velocity error exceeds the value
set in the PMI Tach Loss Maximum Velocity
Error register (register 156/1156). Hex Value: 0020H
Sug. Var. Name: FLT_SPD@
Access: Read only
UDC Error Code: N/A
LED:
N/A
Motor Speed Feedback Broken Wire Bit 8
The Motor Speed Feedback Broken Wire bit
is set if a sine or cosine signal from the
resolver is missing due to a broken wire or if
the resolver gain tunable (RES_GAN%) has
been set too low. Hex Value: 0100H
