One Drive, Any Power, Any Motor. The Unidrive SP is a universal AC and Servo drive with ratings from to 2,hp. No. String, Cause of trip. 1, UU, DC link under voltage. Under voltage trip and restart levels are as follows: Drive voltage rating UU trip level UU restart level. Unidrive SP AC Drive from Emerson/Control Techniques is a complete drive automation range that covers the power spectrum from to 2, hp. All drives .

All drives are going to trip at some point or other. Next time your Unidrive is throwing an error code, the following information may help. This could be because the d. This trip cannot be reset until the voltage falls below the maximum continuous level. If the drive is operating in low emerskn battery mode the over voltage trip level is 1. AC AC instantaneous emerosn current.
SPd Overspeed 8 PS. AC I2t on drive output current see CtL Drive over-heat based on control board temperature see Ld1 Digital output overload 27 O.
If the motor does not stop in 10seconds the drive trips immediately. See trips 36 and 37 below. When this trip occurs the drive mode becomes Open-loop and all the parameters are set to default.
The trip can only be removed by entering a load default sl i. The drive will attempt to stop the motor before tripping except in Regen mode. This trip is initiated eemerson phase loss is detected from d. This is either because the resistance exceeds the maximum measurable value or the drive was not enabled see This trip indicates that the power was removed when parameters were being saved which resulted in an error in a user save parameter bank.
The drive will revert back to the user save parameters that were last saved successfully. If errors occur in both banks an EEF trip is initiated. This trip will occur on every subsequent power up until parameters are saved again. Er Power down save parameters are saved during power down and can be saved when user parameters are saved.
This trip indicates that the power was removed when parameters were being saved which resulted in an error in a power down save parameter bank. The drive will revert back to the power down save parameters that were last saved successfully. This trip will occur on every subsequent power up until power down save parameters are saved again i.
This trip should never occur as there are no write only parameters in the drive. This can occur if the user program file in the drive is being accessed via comms at the same time. P Power module rectifier over temperature OIbr.
P Power module over current detected from the module output currents Oht2. P Power module heatsink over temperature OV. P Power module over voltage PH. P Power module phase loss detection PS.
P Power module power supply fail OIdC. A emmerson has occurred during the alignment of the analogue signals of a SINCOS encoder with the digital emsrson derived from the sine and cosine waveforms and the comms position if applicable. This fault is usually due to noise on the sine and cosine signals.
Hiperface encoder – The encoder type could not be identified during auto-configuration Enc13 Drive encoder trip: EnDat encoder – The number of encoder turns read from the encoder during auto-configuration is not a power of 2 Enc14 Drive encoder trip: EnDat encoder – The number of comms bits defining the encoder position within a turn read from the encoder during auto-configuration is too large.
Unidrive SP Error and Trip codes
The number of periods per revolution calculated from encoder data during auto-configuration is either less than 2 or greater than EnDat encoder – The number of comms bits per period for a linear encoder exceeds Er Data error from electronic nameplate data stored in selected position feedback device. Boot A write to a menu 0 parameter has been initiated via the keypad by exiting edit mode and parameter This occurs when Optn Parameter data or default difference data is being transferred from a SMART card to the drive, but the option module categories are different between source and destination drives.
This trip does not stop the data transfer, but is a warning that the data for the option modules zp are different will be set to the default values and not the values from the card.
This trip also applies emesron a compare is attempted between the data block and the drive. A SMART card is read-only if the read-only flag has been set or the card contains data emwrson with numbers from to Attempting to create data unldrive with numbers from to will always cause a trip.
Unidrive SP – High performance universal AC drive range
Acc An attempt has been made to access a SMART card, but a card is not present or communications failure has occurred between the drive and the card. This trip is also produced if an attempt is made to access a data block that has already been opened by an option module. Typ This trip is produced during a compare if the drive mode in the data block is different from the current drive mode and the file is a parameter or defaults differences file.
This trip is also produced if an attempt is made to transfer parameters from a parameter or default difference to the drive if the drive mode in the data block is outside the allowed range of drive unidrife for the drive.
This trip only occurs if the compare has not already failed with the following trips: Err EnC1 Drive encoder trip: Comms timeout or set up transfer time too long EnC5 Drive encoder trip: Initialisation is required because the encoder type parameter Auto-configuration has been requested by changing parameter Position feedback selected is not valid i.
Servo mode phasing failure because the phasing angle HF Option module in slot 1: This could occur because the module cannot be identified, or the module has not indicated it is running within 5s of drive power-up, unidrlve an internal hardware fault has occurred in the module.
If the module is removed after power-up the drive also produces this trip.
The module has started the watchdog system, but has not subsequently serviced the watchdog within the timeout period. Er Option module in slot 1: The module has detected an error and tripped the drive. The reason for the error is stored in parameter x. The option module is identified by the drive by an option code. The drive stores the codes of the modules fitted when the drive parameters are saved.
The stored codes are compared with the codes from the option modules at power-up. If a module is not present, but a code is stored in drive EEPROM to indicate that it should be fitted the drive trips. HF Option module in slot 2: Hardware fault SL2. Er Option module in slot 2: HF Option module in slot 3: Er Option module in slot 3: Our extensive experience in retrofit and new projects means we have the knowledge to look deep into the control system where we commonly find the peripheral devices are uniidrive rather than the drive module.
Our team of engineers are able to offer on site service and breakdown support throughout the UK to get you up and running again quickly. If you have a faulty drive but don’t require on site support, Drives and Automation are able to repair them at our repair centre in Telford.
Our trained engineers will strip down your drive and send you a repair quotation. If you are happy to proceed we will repair unidrige drive, clean it and load test it before returning emersno to you. Fast turnarounds are usually no problem! Get your faulty Unidrive SP repaired. The Unidrive SP is now a superceded product and is in it’s maintenance period. The maintenance period is expected to last up to ten years subject to raw material and component availability and will end in when no further manufacturer support will unidrivf available.
