How is a "Run Forward" command issued to an Altivar drive that is in 2 wire terminal control mode?

Issue:
How is a "Run Forward" command issued to an Altivar drive that is in terminal control mode?

Product Line:
All current production models of Altivar drives.

Environment:
All current production models of Altivar drives, all serial numbers.

Cause:
Customer is sending a run forward command via the terminals but the drive stays in Rdy status.

Resolution:
A "Run Forward" command is issued on the terminals by closing a connection between +24V terminal (P24 on the ATV212) to the LI1 terminal (F on the ATV212).  Note that other programmed functions or conditions (freewheel stop, run permissive, active fault code) can prevent the drive from running when this signal is connected.'
 

Video: Can the ATV320 be programmed using an external 24Vdc source?

Issue:
Can the ATV320 be programmed using an external 24Vdc source?

Product line:
Altivar 320

Environment:
External 24v
 
Cause:
Need power the ATV320 with external 24Vdc so that it can be programmed

Resolution:
Yes, an external 24Vdc can be provided to the ATV320 in order to power up the display and program the drive.  

To connect an external 24VDC supply to the ATV320, the P24 terminal must be used.
The P24 is an input and output:
- When there is no external supply connected to this terminal, the P24 is an output and delivers 24VDC to the STO circuit.
- When there is an external supply connected to this terminal, the P24 is an input and the drive is supplied by the external supply.
 
The +24 terminal is used to provide 24VDC to the drive digital inputs.
+24 is not designed to be used as an input to supply the control block.

Product Line
ION6200

Environment
Availability

Resolution
The ION6200 with the 480VAC Power Supply option is no longer sold. The only options are the standard plug-in power supply: 100-240VAC, 110-300 VDC power supply and the P24 plug-in power supply (20-60VDC).
 

Video: How is the ATV212 set up for a run permissive logic input?

Wire a dry contact to P24 and a logic input (F, R, or RES).  Program F110 = 0 to remove the always active run permissive.  Then set the logic input = 1 to assign run permissive to it (F111=1, F112=1, or F113=1).  When the remote contact is closed, the drive is permitted to run and is ready for a run command.

Limitations of 32-bit Floating Point Math in a SCADAPack

Problem:

After adding a small number to a floating point registers many times, the stored total loses accuracy over time. What's going on?
NOTE: This scenario can also be seen in use with the FLOW or TOTL function block in TelePACE that is not logging data periodically and resetting the accumulator.

Solution:

The SCADAPack controllers store real or floating point numbers in two 16-bit registers and store it as a 32-bit floating point according to IEEE-754.
Of the 32 bits, one is used for the sign, 8 are used for the exponent and 23 are used for the significand.
There are many handy online floating point converters online.

In Excel, where it doesn’t use 32 bit floating points to store real numbers, you have the ability to store many more digits accurately
For example in Excel:
890.914954861
+ 0.247545139
=891.162500000

If we look at this same calculation with 32 bit floating point math on the SCADAPack:
890.914954861 is stored as a 32 bit FP = 445E BA8F hex = 890.91497802734375 (dec) = 1.10111101011101010001111b9 (binary)
Similarly,
0.247545139 stored as a 32 bit FP = 3E7D 7C79 = 0.24754513800144185556640625 (dec) = 1.11111010111110001111001b-3 (binary)

At the controller level, the ADDF function handles the binary values but it needs to align the decimal points first.
1.11111010111110001111001b-3 (binary) = 0.00000000000111111010111110001111001 b9 which will then get truncated to 0.00000000000111111010111 b9.

Because the two numbers are several orders of magnitude apart, a lot of the precision of the smaller number gets lost in the controller.
1.10111101011101010001111 b9
+0.00000000000111111010111 b9
=1.10111101100101001100110 b9

= 891.1624755859375 in the controller which is a difference of about 0.000024 form the exact value seen above.

NOTE: These effects are magnified as the numbers being added together get further and further apart.

For example, assume we are counting the number of times a discrete event is occurring in a floating point value.
e.g. 1.00 + 1.00 = 2.00; 2.00 + 1.00 = 3.00, etc...

Eventually, we will get to a point where the floating point will no longer be able to continue to increment.
Let's look at 16,777,220 and we add 1
16,777,220 as a 32 bit FP = 4B80 0002 = 16,777,220 (dec) = 1.000000000000000000000100b24 (binary)
1 as a 32 bit FP = 3F80 0000 = 1.000 (dec) = 1.00000000000000000000000b0 (binary)

Again at the controller level, the ADDF function handles the binary values but it needs to align the decimal points first.

1.000 000 000 000 000 000 000 00 b0 (binary) = 0.000 000 000 000 000 000 000 001 b24 which will then get truncated to 0.000 000 000 000 000 000 000 00 b24 since there are only 23 bits available for the significand.

1.000 000 000 000 000 000 001 00 b24
+0.000 000 000 000 000 000 000 00 b24

1.000 000 000 000 000 000 001 00 b24 = 16,777,220

So in 32 bit FP math, 16,777,220 + 1 = 16,777,220 NO CHANGE!

Working within the limitations of 32-bit floating point math.

Time is broken up into logical divisions to make it more manageable: seconds, minutes, hours, days, months, years, etc.

The same will have to be done within the 32-bit FP environment.
In the example above, where a counter was being incremented by 1 at a time, it might be feasible to reset (or rollover) the main counter when it reaches one million and have a separate counter to record the number of rollovers (millions).

NOTE: The use of 1 million as the counter rollover may not be suitable in all applications. It will be dependent on the incremental additions and the precision required for your application.

When the primary counter passes 1 million:
  • increment the secondary count by 1 to count the number of millions.
  • reduce the primary counter by 1 million. This will help prevent a situation where a very small number is being added to a very large number
NOTE: In the example where the totalizer is incremented by an integer value, it may be prefereable to handle the counters as an unsigned double integer. An unsigned double integer has the ability to go up to 4,294,967,295 (232-1)

What will cause the ATV212 drive not to start when the run contact between P24-F is closed?

Issue:
The ATV212 drive does not to start when the run contact between P24-F is closed.

Product Line:
Altivar ATV21 and ATV212

Environment:
All

Cause:
When closing the run contact to logic input F, the VFD displays 0.0Hz.

Resolution:
- Verify that CMOd is set to 0 for terminal control.
- If any network functions are enabled for monitoring purposes, set F108 = 48.
- Check your logic input programming.  Typically F111 = 2 for run forward function.  Other possibilities may combine run forward with other functions.
- Verify that the VFD is in Remote Mode.  The keypad LOC/REM button green LED should be OFF. 
- Verify the VFD 24Vdc power supply by measuring P24 - CC.
- Check that the run circuit is complete by measuring for 24Vdc on F - CC.
- Verify that the VFD has a speed reference.  It may be running at 0Hz, indicated by a red RUN LED in the display.

 

What are the basic wiring connections for the ATV212 drive?

Issue:
What are the basic wiring connections for the ATV212 drive?

Product line:
ATV212, Altivar 212

Environment:
All models

Cause:
Limited wiring details provided with the drive.

Resolution:
The minimum requirements to operate an ATV212 drive are a run command and a speed reference.  By default from the factory, terminals F to P24 are the run forward and run permissive input.  VIA to CC is the default speed reference for 0-10V. 

P24 has its own 24VDC power supply, so use a dry contact closure on F to P24. 

**Note these values and assignments can be changed in the Programming.  These are the default settings only, with CNOd = 0 and FNOd = 1.
