AC-INDUCTION LOW-INERTIA MOTORS
3.7.1. Thermal protection
THE WINDINGS OF HDP MOTORS ARE
MANUFACTURED ACCORDING TO THE
CLASS H INSULATION SYSTEM WITH
CLASS F TEMPERATURE RISE.
WARNING
The thermal sensors integrated into the HDP
motors must be connected to the converter
control circuit and adequate alarm levels must
be set in order to prevent high temperatures and
damage to the insulation of the windings.
By default, the HDP motors are supplied with
3 PTC thermal sensors, which are connected in
series. The threshold value for PTC thermistors
varies based on motor shaft height.
• Frame sizes 280-400: 170°C
3.7.2. Motor feedback
Standard HDP motors can be equipped with an
HTL incremental encoder of 1024 pulses.
The signal connector of the standard encoder
is a 12-pin male connector for industrial
applications embedded in the body of the
motor. The pinout of the encoder connector is
described below.
In order to alter the rotational direction of the
motor shaft, the drive parameters should be
adjusted following the instructions from the
drive manufacturer.
