ATV31 Menu Access. Motor frequency the factory setting is only visible the first time the drive controller is powered up. A dash appears after menu codes to differentiate them from parameter codes.
ATV31 AccParam. SEt- ACC Failure to follow these instructions can result in equipment damage. Ensure that 0. ItH According Current used for motor thermal protection. Set ItH to the nominal current to the indicated on the motor nameplate.
Increase UFr if the torque is insufficient. If the value is too low, the response time is longer. If the value is too high, overspeed or operating instability can result.
StA Frequency loop stability Used only in n and nLd ratios see page If the value is too high, the response time is longer. Adjusts slip compensation for fine tuning of speed regulation. SdC2 Second level of DC injection current 0 to 1.
This function avoids a critical speed which leads to resonance. Setting the function to 0 renders it inactive. After the programmed time has elapsed, the motor is stopped 0 0 to When the frequency reference is greater than LSP and a no limit run command is still present, the motor will restart. SFr Switching frequency 2. With the exception of tUn, which can power up the motor, drive control parameters can only be modified when the drive controller is stopped and no run command is present.
Drive controller performance can be optimized by:. According 0 to rpm, then The tnF fault is displayed. POn: Auto-tuning is performed each time the controller is powered up. LI1 to LI5: Auto-tuning is performed when the logic input assigned to this function transitions from 0 to 1. Note: Auto-tuning will only be performed if no run or braking command has been activated. Auto-tuning may last for 1 to 2 seconds. Do not interrupt the auto-tune! Wait for the display to change to dOnE or nO.
During auto-tune, the motor operates at nominal current. PEnd: Auto-tuning has been requested, but not yet performed. PrOG: Auto-tuning in progress. This behaves in a way similar to the P ratio at no-load and the n ratio with load. If the switching frequency is set to a value higher than 4 kHz, in the event of excessive temperature rise the drive controller will automatically 2 to 16 kHz 4.
It will increase it again when the temperature returns to normal. Refer to page 17 for derating curves. SFr can also be accessed in the SEt- menu. SSL Suppression of the speed loop filter nO: The speed loop filter is active prevents the reference from being exceeded. SCS automatically switches to nO as soon as the nO save has been performed.
Use this function to keep a backup configuration in addition to the current configuration. The drive controller ships with both the current configuration and the backup configuration initialized to the factory settings. FCS automatically switches to nO as soon as this nO action has been performed. InI: Replaces the current configuration with the factory settings. FCS automatically switches to nO as soon as this action has been performed.
These parameters can only be modified when the drive controller is stopped and no run command is present. A stop pulse is sufficient to control stopping. Although this renders the RUN button on the drive controller inactive, the potentiometer still provides the speed reference.
This causes rrS, tCt, and all functions affecting logic inputs to return to their factory setting. If both inputs are high on power up, the controller will run forward. If the forward or reverse input is high when the drive trn controller is powered up, the input must be cycled before the drive controller will start the motor. If forward is activated while the controller is running in reverse, the controller will run forward. Display parameters can be accessed with the drive controller running or stopped.
Some functions have numerous associated parameters. To clarify programming and keep parameter lists short, these functions have been grouped together in sub-. Like menus, sub-menus are identified by a dash after their code, for example LIF-.
When the drive controller is running, the value of one of the monitoring parameters is displayed. The factory setting is output frequency rFr.
To change the parameter displayed, scroll to the desired monitoring parameter and press the ENT key. To retain your selection as the new default, press and hold the ENT key again for 2 seconds.
The value of this parameter will be displayed during operation, even after power to the drive controller has been cycled.
If the new choice is not confirmed by pressing the ENT key a second time, the drive controller will return to the previous parameter after power is cycled. LFr Frequency reference for control via integrated terminal or remote terminal. FrH Frequency reference absolute value 0 to Hz. LCr Motor current A. PEnd: Auto-tuning has been requested but not yet performed. FAIL: Auto-tuning has failed.
If a problem occurs during setup or operation, ensure that all ambient environment,. The first fault detected is stored and displayed, flashing, on the screen. If the drive controller will not start and there is no display indication, check the power supply to the drive controller. Faults which cannot be automatically reset are listed in the table beginning on page To clear these faults: 1. Remove power from the drive controller. Wait for the display to go off completely.

Power Up After a Manual Fault Reset or Stop Command With the factory configuration, when the drive controller is powered up after a manual fault reset or a stop command, the forward and reverse commands must be reset for the drive controller to start.
