Issue:
Maximum motor distance for an Altivar 212.

Product Line:
ATV212

Environment:
All serial numbers for ATV212

Cause:
N/A

Resolution:
The maximum motor cable length is 50m (164ft).  This maximum can be increased with the use of a motor choke.

Issue:
Why is the display blank on the trip unit?

Product Line:
Powerpact P frame, Powerpact R Frame, Masterpact NT, Masterpact NW

Environment:
Applied to Powerpact and Masterpact breakers with trip units with LCD displays.

Cause:
Need to power display of the trip unit without external power supply.

Resolution:
The LCD display on a Micrologic P or H trip unit will be blank unless the trip unit is energized.  Energization requires one of the following sets of conditions:

1. The trip unit is energized by an external 24 Vdc applied to terminals F1-F2 (F1 negative-F2 positive)
2. The trip unit is energized by an FFTK or HHTK test kit
3. There is at least 100 V between two phases, AND the load reaches approximately 20% of the breaker's rated current.

• Note that the display will not power up with primary injection testing unless one of the conditions in bullet 1 above is met.
• Note that Ammeter trip units do not require external power and the display will come on with sufficient current flow alone.

See the following bulletins for more information on these trip units.

Inquiry:
Which parts are needed to upgrade a Masterpact NW breaker from a standard trip unit to a Micrologic 3.0A 5.0P 6.0P 5.0H or 6.0H?

Product Line:
Masterpact NW

Resolution:
Both fixed and drawout breakers need connector S33101 and the trip unit:
3.0A S141A
5.0A S143A
6.0A S144A
5.0P S163A
6.0P S164A
5.0H S173A
6.0H S174A

A neutral CT is required if the breaker is applied on a 4-wire system and new trip unit is a 6.0A, 6.0P, or 6.0H.
A neutral CT is also required if the breaker is applied on a 4-wire system and the new trip unit is a 5.0P or 5.0H being used for ground fault alarm.
See attached table for catalog numbers.

Fixed circuit breakers also need the following parts in addition to connector S33101:
External Voltage Sensing S47506 (P and H trip units only, if voltage sensing is required)
Secondary Disconnects (3) S47075 and (1) S47074
BCM S47405 (if Modbus is required)

Drawout circuit breakers also need the following parts in addition to connector S33101:
External Voltage Sensing S48533 (P and H trip units only, if voltage sensing is required)
Secondary Disconnects (3) S47850 and (1) S47849
BCM S48384 (if Modbus is required)
 

Issue:
Max. cable distance from an ATV312 to the motor

Product line:
ATV312, Altivar 312, ATV320, Altivar 320

Environment:
All models

Cause:
n/a

Resolution:
The ATV312 shows that an output filter or choke is required for any cable distance between the drive and motor exceeding 164 feet (50 meters).  Above 164 feet, there is a change with shielded vs non-shielded.

Shielded cables
From 164 feet to 330 feet (100 meters) you can use the LR filter cell or a motor choke.

Unshielded cables
From 164 feet to 660 feet (200 meters) you can use the LR filter cell or a motor choke.
 

The drive is in 2 wire control (TCC = 2C) and was powered up with an active run command.
Cycle the run command or set TCT to LEL. (IO menu, 2 wire type = level)
https://www.se.com/ww/en/faqs/FA238669/

The drive has an input assigned to Freewheel stop, NST.
The input needs to be active.
https://www.se.com/ww/en/faqs/FA170907/

The drive is in 3 wire control (TCC =3C).
LI1 must be active before the NST will clear.
https://www.se.com/us/en/faqs/FA274804/

The drive is being controlled by serial communication, and drive is not receiving the proper command signal.
The drive will display NST until the correct value has been written to the command word.
https://www.se.com/ww/en/faqs/FA314997/

A loss of a 4-20mA signal is programmed to freewheel stop.
When the input is lost, status goes to NST. Verify the 4-20 mA signal.

The drive is in terminal control, and the STOP button on the integral or remote keypad was pressed.
While in terminal control, the STOP button functions as an E-STOP.  If the keypad STOP button is pressed, the drive will go to NST (excluding the ATV212, which will display a flashing "E"). Power cycle the drive to clear the NST.
https://www.se.com/us/en/faqs/FA164112/

For the ATV61/71 VFD only: If the drive is running, and the voltage applied to the PWR input terminal drops below +19Vdc, the drive will stop and display NST.
You will need to make sure you close the +24 VDC to PWR input and cycle off and on the run command again. Make sure the factory-installed jumper between +24 and PWR is connected firmly. Or if a safety circuit is connected to these terminals, be sure the circuit is closed.
