Drive Fault Register (Continued) 202/1202
Charge Bus Time-Out Fault Bit 6
The Charge Bus Time-out Fault bit is set to
indicate any of the conditions listed below.
Register 222/1222 provides additional
diagnostics if this fault occurs. Hex Value: 0040H

• The DC bus is not fully charged within 10 seconds after the bus enable bit
(register 100/1100, bit 4) is set.
• The drive is on and feedback indicates that the pre-charge contactor has opened.
• DC bus voltage is less than the value stored in the Power Loss Fault Threshold
(PLT_E0%) tunable variable.
• The lack of 115VAC or 24V DC applied to the precharge module on common bus
units (C through H-frame).
If the Charge Bus Time-Out Fault bit is set, verify that incoming power is at the
appropriate level. If the power level is correct, the problem is in the Power Module.
Over Temperature Fault Bit 7
The Over Temperature Fault bit is set if the
thermistor in the Power Module detects a
temperature of 100° C or more. Hex Value: 0080H

UDC Error Code: 1016
LED: P.M. FLT
Resolver Broken Wire Fault Bit 8
The Resolver Broken Wire Fault 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

Resolver Fault Bit 9
The Resolver Fault bit is set if the fuse
blows on the Resolver & Drive I/O board.
This indicates the board has failed and must
be replaced. Hex Value: 0200H
