MT+
Motor temperature sensor, normally closed contact, PTC, NTC,
KTY
Only one motor temperature sensor can be connected
The motor temperature sensor can either be connected to X2A, X2B or X6. It is not
possible to connect several sensors at a time.
Avoiding EMC interferences
The outer cable shield must be connected to the housing of the angle encoder connector
with the greatest possible surface area (with low impedance).
Cable type and configuration [X2A]
The cable names that are stated refer to cables made by Lapp. However, it is also
possible to use comparable cables from other manufacturers, for example Lütze or
Helukabel.
LAPP KABEL ÖLFLEX SERVO 728 CY; 3 x (2 x 0.14) + 2 x (0.5);
with an overall tinned CU shield, angle measurement error up to approx. 0.7° with a cable
length of 25 m, to be used 2 x (0.5) for the resolver carrier.
For highly flexible applications:
LAPP KABEL ÖLFLEX SERVO FD 798 CP; 3 x (2 x 0.14) + 2 x (0.5);
with an overall tinned CU shield, angle measurement error up to approx. 0.7° with a cable
length of 25 m, to be used 2 x (0.5) for the resolver carrier.
