Description
"MC_Power_DB"(
Axis:=_multi_fb_in_,
Enable:=_bool_in_,
StopMode:=_int_in_,
Status=>_bool_out_,
Busy=>_bool_out_,
Error=>_bool_out_,
ErrorID=>_word_out_,
ErrorInfo=>_word_out_);
The MC_Power motion control instruction enables
or disables an axis. Before you can enable or
disable the axis, ensure the following conditions:
•
•
The technology object has been configured
correctly.
•
There is no pending enable-inhibiting error.
The execution of MC_Power cannot be aborted by
a motion control task. Disabling the axis (input
parameter Enable = FALSE) aborts all motion
control tasks for the associated technology object.

STEP 7 automatically creates the DB when you insert the instruction.

In the SCL example, "MC_Power_DB" is the name of the instance DB.

Bool
•
FALSE (default): All active tasks are aborted according to the
parameterized "StopMode" and the axis is stopped.
•
TRUE: Motion Control attempts to enable the axis.
StopMode
IN
Int
•
0: Emergency stop: If a request to disable the axis is pending, the
axis brakes at the configured emergency deceleration. The axis is
disabled after reaching standstill.
•
1: Immediate stop: If a request to disable the axis is pending, this
axis is disabled without deceleration. Pulse output is stopped
immediately.
•
2: Emergency stop with jerk control: If a request to disable the axis is
pending, the axis brakes at the configured emergency stop
deceleration. If the jerk control is activated, the configured jerk is
taken into account. The axis is disabled after reaching standstill.
