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 .

Unidrive SP Error and Trip codes. This trip cannot be reset until the voltage falls below the maximum continuous level. The drive will now accept a decimal value from 0 to at 6. Give us a call at 1. 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.
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. 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.
HF Option module in slot 2: A SMART card is read-only if the read-only flag has been set or the card contains data blocks with numbers from to The Unidrive SP is now a superceded product and is in it’s maintenance period. The drive will display inh, rdy, or run depending on the given commands. This trip also applies if a compare is attempted between the data block and the drive.
HF Option module in slot 1: Er Power down save parameters are saved during power down and can be saved when user parameters are saved.
Unidrive SP AC Drives
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. Leave a Reply Cancel reply Your email address will not be published. This trip is initiated when phase loss is detected from d. SPd Overspeed 8 PS. Boot A write to a menu 0 parameter has been initiated via the keypad by exiting edit mode and parameter GE Automation and Controls Products.
Control Techniques Emerson Unidrive SP SP2402
The speed reference should be displayed here if the digital inputs and the drive sequencer are failing to operate properly. Er Data error from electronic nameplate data stored in selected position feedback device. The Unidrive SPM Modular AC power modules provide the same advanced control feature set as our Panel Mount AC drives but with additional power system flexibility; the AC drives may be arranged to provide a common DC hnidrive system with or without an active front end regenerative, 4 quadrant operation.
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 faulty rather than the drive module. The speed reference is able to be applied in several methods. Position feedback direction incorrect, or motor could not be stopped during the inertia test, or minimal movement phasing test failed see P Power module phase loss detection PS.
The example is a VDC signal on analog input 1.

Contact us for breakdown support. 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 the drive.
FlexiBowl Eemrson Feeding Products.
The drive stores the codes of the modules fitted when the drive parameters are saved. This could occur because the module cannot be identified, or the module has not indicated it is running within 5s of drive power-up, or an internal hardware fault has occurred in the module.
Option module in slot 1: The drive still may not run if the digital inputs and the drive sequencer are each working properly. The drive should operate as seen above if the digital inputs are activated correctly.
Unidrive SP Error and Trip codes – Drives and Automation
Hiperface encoder – The encoder type could not be identified during auto-configuration. This trip should never occur as there are no write only parameters in the drive.
Call us now on to enquire about a refurbished Unidrive SP. Power down save parameters are saved during power down and can be saved when user parameters are saved. See trips 36 and 37 below. The module has started the watchdog system, but has not subsequently serviced the watchdog within the timeout period. Free Standing drives can be ordered to include all of the power input equipment needed to allow immediate connection to the uidrive and to the power supply.
Fast turnarounds are usually no problem! The stored codes are compared with the codes from the option modules at power-up.
