Operating Modes
MPH-02, MPB-02, MPD-02
DOK-INDRV*-MP*-02VRS**-FK01-EN-P
Note:
The control bits (8 and 9) contained in parameter P-0-0116 are
also contained in the control words depending on the master
communication (cf. S-0-0134, P-0-4077, P-0-4068 and
P-0-4028) and can therefore be written via the control words.
One of the operating modes defined in the parameters
S-0-0032 to S-0-0035 is active when:
•
the drive (control section and power section) is ready for operation
- and -
•
the drive enable signal sees a positive edge.
As regards the activation of an operating mode, there are the following
kinds of feedback:
•
With active operating mode the display of the control panel reads "AF".
•
In
parameter
S-0-0390, Diagnostic message number
the respective
diagnostic message number of the active operating mode is displayed
(e.g. "A0101" in "velocity control" mode).
•
In parameter
S-0-0095, Diagnostic message
the active operating
mode is displayed in text form (e.g. "A0101 velocity control").
•
In parameter
P-0-0115, Device control: status word
bit 3 ("drive
follows command values") is used to acknowledge whether the drive is
running in the preset operating mode or not.
•
In parameter
P-0-0115, Device control: status word
bits 8 and 9
("acknowledgment of operating mode") are used to signal the
operating mode presently active.
Note:
The status bits contained in P-0-0115 (3, 8 and 9) are also
contained in the status words depending on the master
communication (S-0-0135, P-0-4078) and can therefore be
read in the status words.

chapter "Master Communication"
Changing the Operating Mode
When drive enable is activated, the drive, after having gone through the
initialization routines, changes to the operating mode that was selected
via bits 8 and 9 of the specific control word of the respective master
communication (S-0-0134, P-0-4077, P-0-4068, P-0-4028 or P-0-0116).
Note:
The change of operating modes is carried out within one
position loop clock (advanced: 250µs; basic: 500µs). Another
position loop clock passes until the command values of the
activated operating mode become effective, because the
initialization of the operating mode is carried out first.
