Note!
Lenze three−phase AC motors and Lenze geared motors can be delivered in
conjunction with the ITD21 pulse encoder by Lenze (512/2048 increments, HTL
output signals) which can be used to generate a two−track speed feedback
(tracks A and B):
ƒ
With function module application I/O: 0 ... 102.4 kHz
ƒ
With function module standard I/O: 0 ... 1 kHz
Example
Speed control with inductive single−track three−wire sensor
The speed control is designed to correct the deviation between the actual speed and the
setpoint speed caused by the effect of the load (motive and generative).
In order to detect the motor speed, the inductive sensor scans e.g. a gear, a metallic fan
impeller or cam. Scanning should take place directly on the motor or within the machine.
