7.9 HEIDENHAIN Synchronous Motors, QSY Series

Motors with
absolute rotary
encoders
April 2007
The HEIDENHAIN synchronous motors have the following features:
Sine commutation
Incremental HEIDENHAIN ERN 1387 rotary encoder
ECN 1313 absolute singleturn rotary encoder or EQN 1325 absolute
multiturn rotary encoder for speed measurement for the QSY 96, QSY 116,
QSY 130,QSY 155 and QSY 190 series (QSY 093B: RON 487)
IM B5 design (mounting via flange) according to IEC 60 034-7
Protection class IP 63 according to IEC 60 529 (shaft hole IP 64)
Cylindrical shaft end according to ISO-R775 and IEC 72 (QSY 041B and
QSY 071B see dimension drawing) with central bore hole according to ISO
866 with thread
QSY 096, QSY 116, QSY 130, QSY 155 and QSY 190 series: Flange
dimensions according to DIN 42 948 and IEC 72
Maintenance-free bearing
Natural cooling
KTY 84-130 resistor probe for temperature monitoring in the stator winding
Thermal class F
Option: integrated holding brake (without much play <= 1°)
The following NC software versions are required for operation of the EcoDyn
synchronous motors:
iTNC 530: 340 420-06 and later
MANUALplus 4110: 354 809-11 and later
CNC PILOT 4290: 340 460-14, 362 796-10 and later
Note
In the performance diagrams, the characteristic curves from the data sheet
are shown in an interrupted, lightface line.
In addition, each performance diagram shows the characteristic curves
determined on a test stand for one motor mounted without thermal
insulation.
If you are using synchronous motors with absolute rotary encoders (EQN 1325
or ECN 1313), remember to reduce the rated torque by approx. 10 %. The
reason is the reduced maximum temperature of the rotary encoder. The stall
torque and the maximum torque are not reduced.
