Encoder - Siemens SIMOTICS M-1FE1 Configuration Manual

Motor components, characteristics and options
4.1 Motor components
● PTC via thermistor motor protection 3RN2013-1GW30, Pt1000 directly connected to
the drive system
● PTC and Pt1000 connected to SME120
More detailed information on this topic is provided in Chapter "Connecting the
temperature sensors (Page 123)".
4.1.2

Encoder

Function
The encoder system has the following functions:
● Actual speed value encoder for the speed control
● Position encoder for closed-loop position control
The rotor position is determined when switching on using the "pole position
identification" software function, see Chapter Commutation angle and pole position
identification (Page 71).
Encoder systems that can be used
● Gearwheel encoder or a
● Comparable hollow shaft encoder system with sinusoidal voltage signals 1 Vpp.
Note
The encoder system is not included in the scope of supply.
