The position feedback did not change or required speed could not be reached during the inertia test see Comms timeout or set up transfer time too long EnC5 Drive encoder trip: CtL Drive over-heat based on control board temperature see The speed reference is able to be applied in several methods.

A write to a menu 0 parameter has been initiated via the keypad by exiting edit mode and parameter If you are wanting to upgrade your obsolete Unidrive SP to an M Series Drive, use our quick reference guide to choose the right replacement Drive for your application:. The drive will revert back to the user save parameters that were last saved successfully. This trip will occur on every subsequent power up until parameters are saved again. Drive voltage rating UU trip level UU restart level Check menu 1 and 2 to determine where it is stopping if the reference is not getting to this point.

This is either because the resistance exceeds the maximum measurable value or the drive was not enabled see Servo mode phasing failure because the phasing angle This trip will occur on every subsequent power up until power down save parameters are saved again i. The Unidrive SP defaults to positive logic. If you are happy to proceed we will repair the drive, clean it and load test it before returning it to you. The logic type is set up at 8.

Contact us for breakdown support. The drive can use digital inputs, keypad, or a field buss networks to give the OK to run. P Power module phase loss detection PS. If an LED or LCD keypad are fitted directly to the drive, and the drive is in keypad reference mode, and the keypad is removed the drive produces this trip.

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. 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.

Check the following parameters: See trips 36 and 37 below. The speed reference will come in on an analog input if you choose a terminal code.

The drive should operate as seen above if the digital inputs are activated correctly.

The module has detected an error and tripped the drive. EnDat encoder – The number of comms bits per period for a linear encoder exceeds P Power module over current detected from the module output currents Oht2.

SPd Overspeed 8 PS. Hiperface encoder – The encoder type could not be identified during auto-configuration.

Under voltage trip and restart levels s as follows: If the module is removed after power-up the drive also produces this trip. This fault is usually due to noise on the sine and cosine signals. Ld1 Digital output overload 27 O. If a module is not present, but a code is stored in drive EEPROM to indicate that it should be fitted the drive trips. The reason for the error is stored in parameter x. 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.

The drive will display inh, rdy, or run depending on the given commands. Hardware fault SL2. DC link under voltage.
