Lenze g500-H User Manual

Feedback
A resolver, incremental encoder and SinCos absolute value encoder are oponally available to
evaluate the speed and posion of the motor sha.
The resolver can be used to measure an absolute value within one revoluon of the rotor. A
SinCos absolute value encoder is used if not only the angle within one revoluon is to be
made available immediately but also the revoluon within a set range. The SinCos absolute
value encoder detects not only the speed and rotor posion but also the posion of the
machine. It consists of a speed sensor system, for example TTL, and an absolute value
informaon recorder, for example Hyperface.
The HTL incremental encoder is used in the frequency inverter range for less dynamic
applicaons.
The TTL incremental encoder can generate a higher number of pulses. It is used for dynamic
applicaons with very high requirements regarding accuracy. If the absolute angular posion
of the drive is required directly aer the system is switched on without performing addional
homing, this can be realized via a resolver or SinCos absolute value encoder.
Resolver
The stator-supplied, 2-pole resolver with two stator windings shied by 90 degrees and a
rotor winding with a transformer winding can record both the speed and the rotor posion,
just like a single-turn absolute value encoder. The rotor posion can be determined within one
mechanical motor revoluon aer a voltage failure.
