MC_Power – Axis activation (power on/off)

Block SymbolLicensing group: MOTION CONTROL

Function Description

The MC_Power block must be used with all axes. It is the only way to switch an axis from disable state to standstill (e.g. operation) state. The Enable input must be set (non zero value) for whole time the axis is active. The Status output can be used for switch on and switch off of the motor driver (logical signal for enabling the power stage of the drive).

The block does not implement optional parameters/inputs Enable_Positive,
Enable_Negative. The same functionality can be implemented by throwing the limit switches (inputs limP and limN of block RM_Axis).

If the associated axis is turned off (by setting the Enable input to zero) while a motion is processed (commanded velocity is not zero), error stoping sequence is activated and the status is switched to off/diabled when the motion stops (commanded velocity reaches zero value).
