Is it possible to buy just the mech (mechanism) from a 31VBER-WE to place in a different series of plate styles ?

No - Unfortunately the mechanism is part of a complex relay system integrated with the electronics on this plate so it is impossible to remove the mechanism and place into a different plate.

Please see below link for more information.

Can the ATV312 (or the ATV31) jog at a value below LSP?

Issue:
Can the ATV312 (or the ATV31) jog at a value below LSP?

Product Line:
Altivar 312, Altivar 31

Environment:
All part numbers, all versions.

Cause:
Application Requirement. Customer wants to operate the drive at a jog speed which is below the normal Low Speed setting.

Resolution:
YES  
The Jog Frequency is adjustable between 0 to 10hz which may be lower than possible LSP setting.
When a run command (forward or reverse) is applied AND the Jog input is turned on the drive will run at the Jog Frequency.
When a run command is present without the Jog input turned on the drive will operate at the Frequency Reference which is adjustable between Low Speed (LSP) and High Speed (HSP).
If the Jog input is turned on while the drive is operating, it will decelerate to the Jog Frequency.  If the Jog input is turned off while the drive is running the drive will accelerate to the Frequency Reference.

How to calculate Energy readings from the raw Integer register data on an Energy Meter

Issue
The energy values are stored across two 16-bit integer registers on an energy meter. 

Product Line
Energy Meter

Environment
Reading and converting Modbus register values

Resolution
The Energy Meter stores energy across two 16-bit integer registers.

Register #1 and Register #2 (Modbus address 257/258 for Register #1 and 259/260 for Register #2). Register #2 is the High WORD and Register #1 is the Low WORD. 

The Multiplier/Divisor table states that both of these registers must be divided by 32 to obtain the real value from the raw data.
The Multiplier/Divisor should NOT be applied to both registers. It is applied to the final value of both registers.

To calculate the Energy the registers must first be arranged as the register list states [2] is the High word and [1] is the Low word.

To make [2] the High word it needs to be shifted to the left 16 bits.
To accomplish this multiply the value in [2] by 65,356.
You will then add this value to the value in [1].
The final value will be divided or multiplied by the correct scaling value. Please see the example listed below.

For this example we will assume an Energy Meter with 300 amp CTs. According to the Integer Multiplier/ Divisor table, 300 amp CTs will give a divisor value, (d), of 32 and a multiplier value, (m), of 0.03125.
We will assume the following register values.
Register #1 = 29,586
Register #2 = 31

Using Divisor Table
kWh = ([R2]*65,536+[R1])/d
kWh = (31*65,536+29,586) / 32
kWh = 64412.56

Using Multiplier Table
kWh = ([R2]*65,536+[R1]) * m
kWh = (31*65,536+29,586) * 0.03125
kWh = 64412.56

*Note the divisor will not always be 32 and the multiplier will not always be 0.03125. For the correct values please see the Integer Multiplier Table.
