MC_Power
The function block MC_Power switches the software enabling of an axis. At Status output operational readiness of the axis is indicated.
 | In addition to software enable it may be necessary to activate a hardware enable signal in order to enable a drive. This signal is not influenced by MC_Power and must be activated separately by the PLC. |
