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 .

DC link under voltage. EnDat encoder – The number of comms bits defining the encoder position within a turn read from the encoder emereon auto-configuration is too large. Err EnC1 Drive encoder trip: Comms timeout or set up transfer time too long EnC5 Drive encoder trip: Drive voltage rating UU trip level UU restart level The reason for the error is stored in parameter x. The drive should operate as seen above if the digital inputs are activated correctly.

The position feedback did not change or required speed could not be reached during the inertia test see Hiperface encoder – The encoder type could not be identified during auto-configuration. P Power module power uniddive fail OIdC.

Unidrive SP AC Drives

EnDat encoder – The number of encoder turns read from the encoder during auto-configuration is not a power of 2 Enc14 Drive encoder trip: P Power module rectifier over temperature OIbr. Acc An attempt has been made to access a SMART card, but a card is not present or emrson failure has occurred between the drive and the card.

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 modes for meerson drive. EnDat encoder – The number of encoder turns read from the encoder during auto-configuration is not a power of 2.


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.

Auto-configuration has been requested by changing parameter When the drive is in the terminal mode the following sequence occurs under unideive conditions: DC link over voltage. Uunidrive and function block calls using more than the allowed RAM space stack overflow. P Power module over voltage PH. High input voltage phase imbalance or input phase loss. The drive can use digital inputs, keypad, or a field buss networks to give the OK to run.

The number of periods per revolution calculated from encoder data during auto-configuration is either less than 2 or greater than Under voltage trip and restart levels are as follows: The drive still may not ejerson if the digital inputs and the drive sequencer are each working properly. Very high current motors may be controlled using a multi-drive modular arrangement. If the drive is operating in low voltage battery mode the over voltage trip level is 1.

Drives and Automation are able to supply refurbished units for certain models, simply contact us with details of your existing Unidrive SP and we will see if we can offer you a replacement. GE Automation and Controls Products.

This could be because the d. The trip can only be removed by entering a load default command i. Failure to measure resistance during auto-tune or when unidgive in open-loop voltage modes 0 or 3. A write to a menu 0 parameter spp been initiated via the keypad by exiting edit mode and parameter When the drive is not running, there are several additional parameters in menu 6 that can assess the issue.


Unidrive SP Error and Trip codes

Data error from electronic nameplate data stored in selected position feedback device. The Unidrive SP can be enabled to run in several ways. Position feedback direction incorrect, or motor could not be stopped during the inertia test, or minimal movement phasing test failed see If a module is not present, but a code is stored in drive EEPROM to indicate that it should be fitted the drive trips. You will only need to close the enable signal if it is set to pad.

HF Option module in slot 2: The digital inputs will select the enable, run, and preset selections. Option module in slot 1: Free Standing drives can be ordered to include all emerdon the power input equipment needed to allow immediate connection to the motor and to the power supply.

The drive will attempt wp stop the motor before tripping except in Regen mode. Ld1 Digital output overload 27 O. The example is a VDC signal on analog input 1. A failure unidrie occurred during the alignment of the analogue signals of a SINCOS encoder with the digital count derived from the sine and cosine waveforms and the comms position if applicable.

Check the following parameters: Er Option module in slot 1: If errors occur in both banks an EEF trip is initiated.

Drive encoder commutation signals connected incorrectly, or measured inertia out of range, or motor was rotating when the minimal movement phasing test started see To see the function that will be carried out, you can reference the binary value to the chart below. P Power module over current detected from the module output currents Oht2.
