10.5.6 Synchronous servomotors in control mode CFC
In general, synchronous servomotors and the corresponding inverters are designed
for a high short-time overload capacity. This allows a multiple of the nominal torque.
When using the following CMP.. motors in the higher speed ranges, it is recommend-
ed to only set the PWM frequencies 8kHz or 16kHz.
• CMP40 – 63 for speed class 6000 min
-1
,
• CMP71 – 100 for speed classes 4500min
-1
and 6000min
-1
.
SEW‑EURODRIVE recommends the use of the following temperature sensors:
• KTY84–130 (SEW‑EURODRIVE designation: KY/KTY)
• Pt1000 (SEW-EURODRIVE designation: PK)
10.5.7 Synchronous servomotors in control mode ELSM
®
The control mode ELSM
®
allows for dynamic use of the entire speed range of the
drive. Reversing and moving through the speed 0 are also possible. The speed must
not permanently drop below the minimum speed of approx. 2% of the nominal motor
speed.
The nominal output current of the inverter must not be lower than 1.5 × I
0
of the con-
nected motor.
The maximum speed must not be dimensioned higher than the rated speed of the mo-
tor.
SEW‑EURODRIVE recommends the use of the following temperature sensors:
• KTY84–130 (SEW‑EURODRIVE designation: KY/KTY)
• Pt1000 (SEW-EURODRIVE designation: PK)
Using the ELSM
®
control mode for hoists and inclining tracks is not permitted.
