Changes in position are recognized by the internal incre-
mental sensor (optical encoder). With a known starting point
the actual position is calculated from the gear reduction
and/or the spindle slope.
Profile Torque Mode Power operation
Operating mode for executing a direct positioning task with
power operation (open loop transmission control) with motor
current regulation
. This operating mode enables an external
nominal torque value (relative to the rated motor current)
to be specified to the controller. Power control takes place
indirectly via the regulation of the motor current. All specifi-
cations on forces/torques refer to the rated motor torque or
current.
Homing mode Reference travel
Execution of a positioning procedure in which the reference
point and therefore the source of the measuring reference
system of the axis are defined, e.g. via a reference switch
within the possible positioning path or with overcurrent
evaluation n the case of movement to a stop.
For commissioning, for testing or for demonstration the fol-
lowing functions are also available via the control panel of
the MTR-DCI-...H2:
– Positioning travel for defining the target position of a pos-
itioning record (Teach Mode), [Settings] [Position set]
– Positioning travel for testing all positioning records in the
positioning record table, [Demo posit tab]
– Positioning travel for testing a certain positioning record
in the positioning record table [Move posit set].
