Before the axis can be moved, it has to be activated. When the “TRUE” signal is applied to the “Enable” input of the block “MC_Power”, the output of the S7-1200 CPU parameterized in the configuration of the “Axis” technology object will be set and the servo drive will be powered up. The “StopMode” input is used to define whether the axis, when deactivated, shall be slowed down by the configured “emergency” deceleration before being disabled (“0”), or whether the axis shall be stopped immediately (“1”). The “Status” output of the block provides feedback from the servo drive and indicates whether the drive is ready for operation. Errors during operation are displayed at the “Error” output and the corresponding error identifier will be displayed at the “ErrorID” output. A list of ErrorIDs is available in the online help of STEP 7 Basic.
