Module description

Introduction

The Power and Energy Solutions product range expands SEW-EURODRIVE’s current line of MOVIDRIVE® modular inverters to include intelligent power and energy management components. In addition to hardware components, the product range includes the MOVIKIT® modular system with software modules for optimum integration at the control software level.

The following figure provides an overview of the software modules of the MOVIKIT® Power and Energy Solutions modular system:

MOVIKIT® PowerMode is designed for applications with energy storage units and provides the user with the following functions, among others:

  • Operating the MDP92A and MDE90A devices from the MOVI-C® CONTROLLER
  • Setting a state of charge in the DC link
  • Disconnecting and synchronizing disconnectable energy storage units
  • Discharging an energy storage unit via a connected braking resistor
  • Connecting diagnostic interfaces of the energy storage units
  • Reading measured values from the devices for use in the IEC program
  • Monitoring the single- or multi-stage fuse concept

INFORMATION

The automatic code generation automatically integrates all blocks required for operation.

Operating modes

MOVIKIT® provides the following operating modes:

  • State of charge control (StateOfChargeControl)
  • Operating mode for regulating a specific state of charge in the DC link or energy storage unit by means of a connected device.
  • Energy storage discharge (StorageDischarger)
  • Operating mode for discharging the DC link via a braking resistor connected to the MDP92A power supply module.
  • DC synchronization
  • Operating mode for synchronizing and connecting or controlled disconnection of separable energy storage units of the MDP92A and MDE90A devices.
  • Automatic mode (automatic)
  • Operating mode for fully automatic operation of the device. The operating mode automatically establishes operational readiness and operates the DC link without external intervention.
  • Operation without energy storage unit (fallback)
  • Operating mode for fully automatic operation of the device. The operating mode can be used to operate the PES system with maximum device power and a fixed voltage setpoint.

For further information, refer to chapter Operating modes.

Additional functions

MOVIKIT® offers the following additional functions with the automatic code generation function in the main function block:

  • StorageMonitor
  • Additional function for connecting diagnostic interfaces of commercially available storage units
  • RemainingRuntimeCalculator
  • Additional function for calculating the remaining system runtime after power failure
  • Single- or multi-stage fuse concept (MultipleFuseControl)
  • Additional function for monitoring the current voltage and the state of the energy storage unit. If necessary, the corresponding fuse is switched on or off.
  • Power monitoring
  • Additional function for monitoring and displaying all power flows in the Power and Energy Solutions system, such as axis power, input power or 24 V consumers.
  • Inrush current limiter
  • Additional function for passive synchronization and connection of an energy storage unit via a precharging resistor for limiting the inrush current.
