![]() The drive holds two banks of user save parameters in EEPROM. Trip initiated from the control word (parameter 06.42) 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. ![]() This is either because the resistance exceeds the maximum measurable value or the drive was not enabled (see 05.12, 05.14, 05.17) link ripple.įailure to measure resistance during auto-tune or when starting in open-loop voltage modes 0 or 3. This trip is initiated when phase loss is detected from d.c. The drive will attempt to stop the motor before tripping except in Regen mode. Normally a motor load of between 50 and 100% or drive rating is required to trigger the trip. High input voltage phase imbalance or input phase loss. 1233, 1244, etc.) into parameter x.00 before reseting the drive. The trip can only be removed by entering a load default command (i.e. When this trip occurs the drive mode becomes Open-loop and all the parameters are set to default. Serial comms timeout with remote keypad on drive 485 comms port If the motor does not stop in 10seconds the drive trips immediately.Īnalogue input 2 current mode: current loss (see 07.11)Īnalogue input 3 current mode: current loss (see 07.11) The drive will attempt to stop the motor before tripping.

This trip cannot be reset until the voltage falls below the maximum continuous level.ĭrive voltage rating Instantaneous trip Max continuous level link voltage has exceeded the maximum level or has remained above the maximum continuous level for more than 15s. Under voltage trip and restart levels are as follows:ĭrive voltage rating UU trip level UU restart levelĭC link over voltage. Next time your Unidrive is throwing an error code, the following information may help. Simple startup ‑ pushbutton set up of all the parameters, the 10 most used parameters are on the front of the drive covering 90% of the applications.All drives are going to trip at some point or other.Simple connection ‑ clearly marked easy access terminals. ![]() Simple installation ‑ choose between panel mounting or DIN‑rail mounting (up to 2 hp).Description Emerson SKB3400037 Inverter AC Drive Commander SK SeriesĬontrol Techniques AC Drives, Commander SK Seriesĭrive, AC, 0.50HP, 460V, 1.3A, CT, 460Vin 3PH 0.50HP 1.3A VT W/DB TRANS 8.1″Hx3.4″W圆.2″D COMMANDER SK Features of Emerson SKB3400037 AC Drive Commander SK Series
