Function Block MC_Power

General Information
Available as of PLC runtime system V2.2
Included in library MC_Block_AC500_V11.lib
Type Function Block with historical values

This Function Block controls the power stage (on or off). If this Function Block is called with Enable=TRUE while being in Disabled, this either leads to StandStill if there is no error inside the axis or to ErrorStop if an error exists.

Note

  • If the Function Block MC_Power is called with the Enable true while being in Disabled, this either leads to Standstill if there is no error in the axis, or to ErrorStop if an Error exists.
  • It is possible to set an error variable when the Command is TRUE for a while and the Status remains FALSE with a Timer Function Block and an AND Function (with inverted Status input). It indicates that there is a hardware problem with the power stage.
  • If power fails (also during operation) it will generate a transition to the state ErrorStop.
  • When MC_Power is called with Enable FALSE the axis goes to state Disabled for every state including ErrorStop.

See the following chapter to check if this Function Block is supported by the used axis implementation: Overview

For this Function Block there is a visualization in the Library MC_Blocks_AC500_V11.

See the following chapter for a list of available data types: Overview

Using this Function Block with FM562

Input variable AXIS of MC_Power must be the same with input variable AXIS of PTO_FM562_ACCESS. Therefore, the specific axis information contained in AXIS_REF structure can be transferred from PLCopen Library to PTO Library and then to FM562 IO mapping.
