Changes in position are detected by the internal increment
generator (optical encoder). With a known starting point, the
actual position is calculated from the gear reduction and/or
the spindle pitch.
Profile torque mode Force mode
Force control (open loop transmission control) by controlling
the motor current
. This operating mode allows specification
of an external nominal torque value (relative to the nominal
motor current) for the controller. Force control occurs
indirectly via the control of the motor current. All specifica-
tion for forces/torques are defined in relation to the nominal
motor torque or the nominal motor current.
Homing Mode Homing
Execution of a positioning task for determining the reference
point and thus also the origin of the dimensional reference
system for the axis, e.g. via a reference switch within the
possible motion range or via overcurrent monitoring when
moving against a stop.
The following additional functions for commissioning, testing
or demonstration are available from the control panel of the
MTR-DCI-...-H2:
– Positioning travel for defining the target position of a pos-
itioning record (Teaching), [Settings] [Position set]
– Positioning run to test all position set records in the posi-
tion set table [Demo posit tab].
– Positioning run for testing a certain position set record in
the position set table [Move posit set].
