Issue:
Activating automatic restart function on the Altivar Process drives

Product Line:
Altivar Process Drive (ATV630, ATV930, ATV650, ATV950, ATV660, ATV960, ATV680, ATV980)

Environment:
All Products of Altivar Process Drive 

Cause:
Automatic restart after fault.

Resolution:
Automatic restart will only work if the drive is being controlled from the terminal strip in 2 wire control (will not work in HMI mode or while using Serial Communication) If the fault is resettable and the run command is maintained.

Go into Complete Settings, Command and reference, and set 2 wire type to level control.
Go into Complete Settings, Error/Warning Handling, Auto fault reset, and set auto fault reset to yes.
The drive will attempt to reset the fault for the length of time programmed in the Fault Reset Time parameter (default is 5 minutes) as long as the run command remains present on the drive.

It is also advisable to activate to Catch on the Fly in case the motor is already spinning when the drive restarts. (Complete Settings -> Error/Warning Handling)


Conditions that have to be met:
Must be in 2 wire control with run command present.
The automatic restart function has to be activated.
The condition that caused fault code has to have been resolved.  

The lists of fault codes that can be cleared automatically are listed in the ATV600 Programming Manual and ATV900 Programming Manual.


 

Issue:
Motor is smaller than the available drive.

Product Line:
All Altivar (ATV) drives

Environment:
All Environments

Cause:
Motor and drive sizing does not match.  Motor is smaller HP than Drive.

Resolution:
YES.
In most cases a drive can control a motor with lower HP (and current) rating.

The motor nameplate information will have to be entered correctly to ensure proper control of the motor and that the overload protection is enabled.   
In most cases the Overload protection adjustment range is the limiting factor.  If this parameter can not be set down to the motor FLA, an external overload relay will have to be provided.
When using small motors on a larger drive the Sensorless Flux Vector motor control modes may not work well.  Changing the motor control type to linear Voltage/Frequency is usually best.
Consult the programming manual for the drive being used for details on these parameter adjustments.
If working with an enclosed drive that has full voltage bypass, the Overload Relay in the bypass circuit may need to be changed if it's OL settings can not be adjusted down to the motor FLA.

NOTE that this does not pertain to Softstarts.   Softstarts will not work well with motors that are less than 40% of their continuous current rating.

MAXBAR with neutral terminal block can be used to distribute active and neutral in the row with main switch. Use the connectors provided with MAXBAR to take active and neutral feed from the row with main switch to take the feed to other rows. You can follow the same process for other rows in switchboard.

Issue:
Local/Remote button does not work

Product line:
Altivar 600 Family: ATV630, ATV650, ATV660, ATV680
Altivar 900 Family: ATV930, ATV950, ATV960, ATV980

Environment:
All

Cause:
Default programming

Resolution:
The factory setting for Process drives' Local/Remote button is 'deactivated'.
To activate it:

1. go to menu 5: Complete Settings (CSt-)
2. go to menu 5.5 for ATV600: menu 5.4 for ATV900: Command and Reference (CrP)
3. go to parameter HMI cmd. (bMP) and change it from Deactivated (diS) to Bumpless (buMP) or to Stop.

Bumpless means that if transitioning from Remote to Local the drive will continue in it's last state...so if it was running, it will continue to run at the same speed, but can now be controlled by the keypad in local mode.  When changing from local back to remote the drive will only run if the remote controls are calling for it to run and it will automatically switch to the remote speed reference.
Stop means that the drive will be stopped when switching between Local and Remote and a new run command will be required.
