Activation of the drive (MC_Power)FB name MC_PowerTransition into the status "Standstill: disable" or "Standstill: powered"VAR_IN_OUTAxis INT Axis-ID (library constants)VAR_INPUTEnable BOOL Activates the module;as long as Enable=TRUE, the drive is activated.With Enable=FALSE, the drive stops with the ramp definedfor the error (see page 74).Please observe:The configured error ramp is limited. The error rampwill not be smaller than the deceleration set in the lastmotion set.VAR_OUTPUTStatus BOOL State of the power output stage (TRUE=drive activated,FALSE=drive deactivated)Error BOOL Error when deactivating the driveNotes: If the input parameter "Enable" = TRUE, all enables of the drive will be set. All enables will be reset if the input parameter"Enable" = FALSE, the axis decelerates with the configured error ramp to speed =0. Note on Compax3 Servo: During automatic commutation, the output "Status" isnot set to TRUE for activation, but rather not until after automatic commutationhas been successfully completed. An enable is denied until the intermediate circuit is loaded, this may take up to 2swhen switching on Compax3H for the first time. If the drive is in error state (see page 302) (error reaction 1: controller active) andthe enable of the MC_Power is deactivated, the drive is deactivated (errorreaction 2). C3 powerPLmC Note: This module is also available as group function block. Youcan then trigger this function for the entire Compax3 group.Enable : BOOLAxis : (VAR_IN_OUT)Status : BOOLError : BOOLMC_Power
