+13.7 to +15.2 V, 300 mA short-circuit proof (electronically protected)
If overload occurs: alarm A60018
Load: ≤ 5.25 mA at 15 V (without switching losses)
Pulse duty factor: 1:1
For information on cables, cable length, shield support, input pulse
levels, hysteresis, track and pulse frequency, see SINAMICS DCM
DC Converter Operating Instructions
±10 V, max. 2 mA short-circuit proof, resolution ±15 bits
Sensor acc. to p50490 (refer to SINAMICS DCM List Manual)
The cable to the temperature sensor on the motor must be shielded
and connected to ground at both ends.
The cables for the Temp 1 and Temp 3 connections to the
temperature sensor must be approximately the same length.
The sense cable (Temp 2) is used for compensating the
cable resistances. If you are not using a sense cable, terminals 54
and 55 must be connected.
Connection without/with sense cable:
24 V DC, short-circuit proof
Max. load 200 mA (terminals 9, 10, 57, 58, 59 and 60 combined),
internal supply to digital ground and analog ground
