10.12 Encoder evaluation

Encoder evaluation

General information

The SINAMICS DC MASTER can evaluate speed/position encoders.

Two encoders can be evaluated simultaneously. Encoder 1 is connected to connector X177

on the CUD. Encoder 2 is connected to encoder module SMC30, which is connected via

DRIVE-CLiQ with the CUD.

Encoder 1 is often referred to as the motor encoder as it is normally attached directly to the

Encoder 2 is often referred to as the load encoder as it is normally attached directly to the

Table 10- 47 Supported encoder types

Setting for p0400

✓ = encoder type is supported

x = encoder type is not supported, setting not permitted

The encoder evaluation determines the current actual speed value and the actual position

value for both encoders. (See function diagrams 4704, 4710 and 4711 in the SINAMICS

DCM List Manual.)

Furthermore, for both encoders the encoder control word and the encoder status word

according to PROFIdrive are available. (See function diagrams 4720, 4730 and 4735 in the

SINAMICS DCM List Manual.)
