10.17.2 Motor ROTAX®
MOTOR TYPE
The connected motor type of ROTAX® series will be
recognized and shown automatically.
I STOP
Continuous current limitation in standstill.
I RUN
Continuous current limitation while moving.
NUMBER OF POLE PAIRS
Number of pole pairs of AC / DC / EC brushless servo
motors. For DC brush-type servo motors, set POLE
PAIRS to 0.
INC PER REVOLUTION
Number of encoder increments per revolution by AC / DC /
EC brushless servo motors. Not used for DC brush-type
servo motors.
PHASE DIRECTION
Direction of phase control
U, V, W or V, W, U, depending on motor type. Can be
detected with command PHDD.
With DC brush-type servo motors:
PHASE DIR = 0, if motor shaft turns clockwise with direct
DC-supply voltage.
PHASE DIR = 1, if motor shaft turns counter clockwise with
direct DC-supply voltage.
PHASE OFFSET
Correction of electrical angle, in accordance with the
orientation of the coil to the magnet. Value for the most of
rotary motors PHASE OFFSET = 0
ROTOR INERTIA
Rotor moment of inertia of the motor, with factor 10
9
.
TORQUE CONST
Torque constant of the motor, with factor 10
6
.
INDUCTANCE
Phase to phase inductance of the motor.
RESISTANCE
Phase to phase resistance of the motor.
