RA7x/SA7x Pocket Reference Guide 45
3A—Write and Write Protected
Error Description: The drive was write protected and
detected the assertion of the internal write gate.
FN: 59—wrg&wrt.prt.—write gate and write protection
both asserted
Most Probable Cause: ECM, SDI controller, SDI
cable
3B—AGC Fault
Error Description: Either the automatic gain control
(AGC) circuit has failed or read signal amplitude
variations have far exceeded the capability of the AGC
circuit to maintain a proper signal lock. The latter of
these may be caused by a severe signal degradation
ratio (SDR, erasure) from a defective HDA.
FN: 5D—agc.lck.flt.—automatic gain control lock fault
Most Probable Cause: ECM, HDA
3C—Servo Faults
Error Description: There are hardware-detected
inconsistencies with the servo system. These are
divided into two categories: actuator faults and servo
faults.
FN: 57—hrd.svo.flt.—hard servo fault
Most Probable Cause: ECM, HDA
41—SDI Command/Response Timeout
Error Description: The drive detected the start of an
incoming SDI command or the transmission of an SDI
response, but the operation did not complete within a
specified time period.
FN: A8—exp.rsp.tmr.—expired response packet timer
FN: A9—exp.cmd.tmr.—expired command packet timer
Most Probable Cause: ECM, SDI controller, SDI
cable
