Magnetek/Yaskawa GPD 515 AC Drive Fault Indications11/17/2016Alarm and fault indication on the Magnetek/Yaskawa GPD 515 AC drive is how the control informs a user that there is a problem. Failure in the GPD 515 / G5 series falls into two categories. Alarm condition and fault condition. An alarm indication is a warning that a drive trouble condition will soon occur or that there is an error in programming. The drive will continue to operate during this condition. A fault indication is displayed when the fault relay has been tripped. If this occurs, the motor will coast to a stop. Some quick and general information on the fault indications and causes are listed in this article.BUS – Communication error from serial communication cardCALL – Control data not received when power supply is turned onCE – Control data was not received after initial communicationCF – Drive cannot determine the speed of the motorCPF00 – Communication between the keypad and drive was not establishedCPF01 – Communication error between the keypad and driveCPF02 – Baseblock circuit faultCPF03 – EPROM faultCPF04 – Internal A/D faultCPF05 – External A/D faultCPF06 – Option card connection failureCPF20 – A/D converter faultCPF21 – Communication self-diagnostic errorCPF22 – Communication model code errorCPF23 – Communication DRAM errorDEV – Speed deviationE-15 – Communications errorEF – External faultEF0 – Fault from option cardEF3 – Fault at terminal 3EF4 – Fault at terminal 4EF5 – Fault at terminal 5EF6 – Fault at terminal 6EF7 – Fault at terminal 7EF8 – Fault at terminal 8E-10 – SI-F Communication errorERR – EPROM write-in faultFbL – PID feedback reference lossGF – Ground faultLF – Output phase lossOC – Overcurrent faultOH – Cooling fin overheatOH1 – Drive overheatOH2 – Drive overheat pre-alarmOL1 – Motor overloadOL2 – Drive overloadOL3 – Overtorque detect 1OL4 – Overtorque detect 2OPE01 – Drive capacity selection faultOPE02 – Parameter set out of rangeOPE03 – Multi-function input setting faultOPE05 – Option card selection errorOPE06 – PG-X2 card not installedOPE07 – Multi-function analog input selection errorOPE08 – Selection parameter errorOPE10 – V/f data setting faultOPE11 – Carrier frequency parameters set out of rangeOPR – Keypad disconnected while in run modeOS – Motor overspeed faultOV – Overvoltage faultPF – Drive input phase missingPGO – Pulse generator wires are disconnectedPUF – Fuse blownRH – Braking resistor overheatRR – Braking transistor failureSC – Short circuit on drive output terminalsSVE – Zero servo faultUV – Undervoltage or momentary power lossUV1 – Main circuit undervoltageUV2 – Control circuit undervoltageUV3 – Main contactor faultWhen your Magnetek/Yaskawa GPD 515 drive experiences a fault or alarm, often the fault condition can be reset and operation can continue. Sometimes it will take a minor adjustment to a parameter or set of parameters. Some faults can be cleared be unseating and reseating an option card to make sure there is a good connection. If a fault cannot be cleared by resetting the drive, taking minor corrective action, or cycling power to the drive, a good next step to try is to disconnect the motor wires from the drive output terminals. If the fault can now be reset, the cause is most likely the motor or wiring to the motor. However, if the fault remains and still cannot be reset, the problem is within the drive. At that point you can call on the repair experts at Precision Electronic Services, Inc. at 800-732-4695, to fix your drive and get your GPD 515 or G5 series AC drive back into production.
