Tip:
Lenze three-phase AC motors and Lenze geared motors can be supplied with the Lenze pulse encoder ITD21 (512/2048
increments, HTL output signals). This makes it possible to set up two-track speed feedback (tracks A and B) when using the
Application I/O function module.
Speed control
Application examples
Control applications (speed control)
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.
Functions used
• Internal process controller for speed control.
• Speed setpoint e.g. via diagnosis terminal
(hand-held keypad)
• Actual speed value as pulse train via digital input
(configured as frequency input).
• DC braking, if the value of the setpoint is less than
a configurable threshold.
