Info
The accuracy of the temperature measurements might be impacted if the temperature
sensor's wires are long. See accuracy specification in the IMD 100 Datasheet.

5.3.3 Connecting the resolver (X4)

The resolver is a measuring system for a motor revolution. It is robust and insensitive to high
temperature. The architecture of a resolver corresponds to a rotating transformer. The IMD is
compatible with most industrial resolvers.
The rotor is powered by the reference. The stator provides the modulated frequency of the rotary-sine
and cosine signals. The amplitudes of these signals are digitized and evaluated in the servo amplifier.

The digitized signals are used for position and speed control.
Pt4 and KTY motor temperature sensors can be connected to the IMD through either X3 or X4. Never
connect the same sensor to both connectors
The resolver wires are connected to a male 15 pole D-sub connector as follows:
