Process input data

The following table shows the process input data from the inverter to the higher-level controller for control via fieldbus with 8 process data words:

Word

Bit

Function

PI 1

Status word

0

"1": Device is ready for operation and no error is active in the software module.

1

Reserved.

2

"1": Output stage enable.

3

"1": Power supply OK.

MDE90A: The "Power supply OK" signal is transmitted by the power supply module (module bus master). The power supply is sufficient for operation.

4

"1": Supply active (B -> A).

The device feeds a current ≥ 1 A into the DC link and the output stage of the device is enabled.

5

"1": Supply active (A -> B).

The device feeds a current > 1 A into the connected energy storage unit and the output stage of the device is enabled.

6

Energy storage unit connected.

"1": The energy storage unit is connected to the DC link (in case of connectable energy storage units). The software module has successfully completed a corresponding synchronization process and has connected the storage unit.

7

"1": Setpoint reached – the active operating mode signals that the setpoint has been reached.

  • 500/501 – StateOfChargeControl:
  • Setpoint for state of charge reached.
  • 521 – DC synchronization:
  • Storage unit successfully disconnected.
  • 522 – DC synchronization:
  • Storage unit successfully synchronized and connected.

8

"1": Error.

9

"1": Warning.

10

  • "1": The B-side is the controlled side.
  • "0": The A-side is the controlled side.

(Applies only to the MDE90A device.)

11

"1": State of charge low.

The state of charge has a value below the defined operating range.

12

"1": State of charge high.

The state of charge has a value above the specified operating range.

13

"1": Current limit active.

A current limit is set by the software module and restricts the power supply.

INFORMATION: The operation of connected axes should be set.

14

"1": Standby mode active.

15

MOVIKIT® Handshake Out.

PI 2

Actual value state of charge

  • Depending on the specified setpoint type:
    • Absolute voltage value [±10-1 V]
    • Percentage value of the operating range [10-1%]
    • Absolute energy value [kWs]

PI 3

Status

Error-suberror

  • With active device error:
  • Bit 0 to 7 ErrorSubID, Bit 8 to 15 ErrorID
  • With active software module error:
  • Error ID of the software module
  • With warnings: Warning code
  • Without errors or warnings:
  • Active FCB of the connected device

PI 4

Actual value charging power

  • Depending on the specified setpoint type:
    • Absolute current [±10-1 A]
    • Power [±101 W].
