Configuring the UDC Module’s Registers 3-31
I/O Status Register (Continued) 201/1201
Tuned Iz Done Bit 10
The Tuned Iz Done bit is set to indicate that
the system has successfully tuned the value
in STATOR_IZ_E2%. Hex Value: 0400H
Sug. Var. Name: TUNED_IZ@
Access: Read only
UDC Error Code: N/A
LED:
N/A
Note that this bit is used in Constant Power applications only. Refer to Appendix E
for more information on this procedure.
Drive Fault Register 202/1202
The bits in the Drive Fault register indicate the cause of a drive shutdown. The bits in this register are latched
until they are reset by setting the Fault Reset bit (bit 8) of the Drive Control register (100/1100, bit 8). After
turning the Fault Reset bit on, the drive may be re-started after turning the desired command bit in register
100/1100 off and then back on again. If the fault condition still exists, the identifying bit in this register will
immediately set again.
The fault conditions reported in this register result in turning off the drive. The UDC task is not stopped
automatically if a drive fault occurs unless it is specifically instructed to in the application task. The user must
ensure that the AutoMax application task tests register 202/1202 and takes appropriate action if a fault
occurs.
Note that the status of this register is also reported in the error log for the task in which the error occurred.
Power Module Overtemperature Bit 0
The Power Module Overtemperature bit is
set if either of the following conditions
occurs: Hex Value: 0001H

UDC Error Code: 1016

• The PMI detects that motor current exceeds 100% of the Power Module’s
continuous capacity at maximum current for a pre-determined amount of time. At
maximum rated current, this trip will occur in 0.5 second. Trip will occur faster if
the motor is stalled instead of running.
• Hardware detects that the temperature of the Power Module’s heatsink exceeds
the maximum rating.
Instantaneous Overcurrent Bit 1
The Instantaneous Overcurrent bit is set if
any of the three motor feedback currents (Iu,
Iv, Iw) exceeds 133% of maximum rated
RMS current. Hex Value: 0002H
