Values

Name

Description

iTcMc_ProfileConstAcc

Only present for compatibility reasons; has been replaced by iTcMc_ProfileCtrlBased.

iTcMc_ProfileTimePosCtrl

Only present for compatibility reasons; no longer supported.

iTcMc_ProfileCosine

Only present for compatibility reasons; no longer supported.

iTcMc_ProfileCtrlBased

The control value for the drive is assembled from sections of constant acceleration and deceleration. Time (acceleration, change of velocity, stop) and distance (positioning) function as controlling values.

This generator type can optionally operate in purely timer-controlled mode with continuously closed position controller.

iTcMc_ProfileTimeRamp

The control value for the drive is generated with time-controlled ramps for accelerations and decelerations. The controlling parameters are time (acceleration, velocity change, stop) and path (braking, stopping).

This generator type is intended for axes, which only have digital cams instead of an encoder.

iTcMc_ProfileJerkBased

The control value for the drive is assembled from sections of constant acceleration and deceleration. The deceleration is reduced with limited jerk towards the target. Optionally, the acceleration can be increased with limited jerk. Time (acceleration, change of velocity, stop) and distance (positioning) function as controlling values.

Some functions are not supported by this generator type, or not fully.

This generator type can optionally operate in purely timer-controlled mode with continuously closed position controller.

iTcMc_ProfileBufferedJerk

reserved

iTcMc_ProfileSwitchedVelo

Reserved for sector-specific packet.

iTcMc_Profile_TestOnly

This type is only intended for internal testing of function block prototypes, which have not yet been released. It cannot be set via the PlcMcManager.
