9 Diagnostics
The display on the drive gives various information about the status of the drive. These
fall into three categories:
• Trip indications
• Alarm indications
• Status indications
For further information regarding trips, refer to the Mentor MP User Guide.
9.1 Trip indications
Table 9-1 Trip indications
Users must not attempt to repair a drive if it is faulty, nor carry out fault diagnosis other
than through the use of the diagnostic features described in this chapter.
If a drive is faulty, it must be returned to an authorized Control Techniques distributor
for repair.
Trip Number Description
AOC 3
Instantaneous output over current detected: peak output current greater than
225%
AOP 158
Voltage has been applied to the armature but no current feedback has been
detected
AtL.Err 161
Power processor armature timing loop cannot operate with the current PLL
synchronization and the firing angle demand
C.Acc 185 SMARTCARD trip: SMARTCARD read/write fail
C.Boot 177
SMARTCARD trip: Menu 0 parameter modification cannot be saved to the
SMARTCARD because the necessary file has not been created on the
SMARTCARD
C.BUSy 178
SMARTCARD trip: SMARTCARD can not perform the required function as it is
being accessed by a Solutions Module
C.Chg 179 SMARTCARD trip: Data location already contains data
C.cpr 188
SMARTCARD trip: values stored in the drive and the values in the data block
on the SMARTCARD are different
C.dat 183 SMARTCARD trip: data location specified does not contain any data
C.Err 182 SMARTCARD trip: SMARTCARD data is corrupted
C.FULL 184 SMARTCARD trip: SMARTCARD full
cL2 28 Analog input 2 current loss (current mode)
cL3 29 Analog input 3 current loss (current mode)
CL.bit 35 Trip initiated from the control word (Pr 6.42)
C.Optn 180
SMARTCARD trip: Solutions Modules installed are different between source
drive and destination drive
C.Prod 175 SMARTCARD is not compatible with this drive
C.RdO 181 SMARTCARD trip: SMARTCARD has the read-only bit set
C.rtg 186
SMARTCARD trip: the voltage and/or the current rating of the source and the
destination drives are different
C.Typ 187 SMARTCARD trip: SMARTCARD parameter set not compatible with drive
dESt 199 Two or more parameters are writing to the same destination parameter
EEF 31
EEPROM data corrupted: drive mode becomes open loop and serial comms
will timeout with remote keypad on the drive RS485 comms port.
EnC1 189 Drive encoder trip: encoder power supply overload
