) Note!
Lenze three-phase AC motors and Lenze geared motors are
available with Lenze pulse encoder ITD21 (512/2048 increments,
HTL output signals). This enables a two-tracked speed feedback
(tracks A and B)to be built up:
l With Application I/O function module: 0 ... 100 kHz
l With Standard I/O function module: 0 ... 1 kHz
Speed control with inductive, single-tracked 3-conductor sensor
The speed control is to compensate the difference between actual speed and
speed setpoint caused by load (motor and generator mode).
The motor speed is detected by an inductive sensor (e.g. gear, metallic fan wheel,
cam). The sensor can detect the speed either directly at the motor or in the
machine.
