The following table lists the cause associated with the error. Doing so could cause damage to the inverter. Dust, steel filings and other foreign matter can damage insulation, causing unexpected accidents, so take special care. Notice the four wire exit slots on larger model inverters in the housing partition. Error Codes An error code will appear on the display automatically when a fault causes the inverter to trip. If dust accumulates on the fan and heat sink, it can cause overheating of the inverter. Tilt upward after both locking tabs are free.
Eliminate the error cause, then clear the error Reset. The electronics housing and front panel are built onto the front of the heat sink. The right-most column of the tables is blank, so you can record values you have changed from the default. This part is a logic circuit. If you find a significance difference, a problem may exist. A020 Multi-speed 0 setting 0. The inverter has a surge protector between the main circuit terminals above and the chassis ground.
Otherwise, vibration may cause the keypad to loosen in the future. Set the bottom edge of the keypad into the inverter keypad bay. Never touch the heat sink during or just after operation; it can be very hot. Make sure it matches the product part number you ordered. This involves just a few parameters for most applications.
To initialize the inverter, follow the steps below. A parameter will not change after an edit reverts to old setting. Inverter Keypad - The inverter uses a digital operator interface, or keypad. Smaller models have two mounting holes, while larger ones have four. The connector can be pulled forward easily after the screws are removed. Press inward on both sides. The mounting holes are predrilled in the heat sink for your convenience.
The upper row of power terminals connect to optional dynamic braking components. To remove the keypad, locate the retention latch as shown to the right. The two locking tabs are the ones which you will need to press to remove the cover. Press downward on the latch, while gently pulling toward you. Error Code E 01 E 02 E 03 E 04 Name Over current event while at constant speed Over current event during deceleration Over current event during acceleration Cause s The inverter output was short-circuited, or the motor shaft is locked or has a heavy load.
Most importantly, the input power and motor wires will be disconnected from the inverter. All feature the same basic keypad and connector interface for consistent ease of use. Just follow the steps to perform the test: 1. The keypad will tilt forward, as two retaining tabs at the bottom edge of the keypad also hold it in place. Troubleshooting and Maintenance 6—8 Restoring Factory Default Settings Restoring Factory Default Settings You can restore all inverter parameters to the original factory default settings for the intended country of use. When you remove the front cover, you can set the mode switch and set wire at the control-terminal, the main-terminal and the intelligent relay output terminal. Try gently shifting the connector side-to-side while pulling, if having difficulty.
Tilt the top edge of the keypad forward. Be sure to use tools with insulated handles. Remo ve the mon itor cover, front cover and rear cover. Continue until the cover latches into place. There are some monitor or function-code for testing and maintenance which is not released for users. If it fails to restart, then the alarm trips to record the under-voltage error event. Installing the Cover Slide type 1.
While pressing inward on the housing, it is helpful to wiggle the cover side-to-side in order to release the locking tabs. When removing the monitor cover, please remove the communication cable from the front cover side. Slide the cover forward and away from the keypad until the top edge of the cover reaches the notch in the inverter chassis. This section presents the parameters in a format oriented toward the keypad on the inverter. Insert the minus screw driver etc to the insert point, and remove the upper cover.
After you fill registration form, hitachi inverter sj700 2 series instruction manual ebooks are available via our partner sites, information are available. Press downward on the cover at the two areas indicated to release the retaining tabs. The logic input connector top connector can be removed by pulling gently upward as shown below left. By the way, primary released product is different from not primary secondly - one about the way to remove the fan. Insert the minus screw driver between the cooling fin and the housing, and unlock the tabs 4 points at the left and right side.
The capacitor handles high voltage and current as it smooths the power for use by the inverter. It is easily removed to allow you to plug a communications cable into the modular connector. After the section on wiring, this chapter will show how to use the front panel keys to access functions and edit parameters. Thus, look no further as here we have a range of best sites to download eBooks for many those books. To access the data, use the monitor functions Dxxx and select D081 for details about the present fault En.
