10.7Definition of pulse encoder, speed sensing using pulse encoder

The following types of pulse encoder can be used (type selection in P140):

1.Pulse encoder type 1

Encoder with two pulse tracks mutually displaced by 90° (with/without zero marker)

Track 1

X173 28, 29

Track 2

X173 30, 31

Zero marker

X173 32, 33

2.Pulse encoder type 1a

Encoder with two pulse tracks mutually displaced by 90° (with/without zero marker). The zero marker is converted internally to a signal

in the same way as on encoder type 1.

Track 1

X173 28, 29

Track 2

X173 30, 31

Zero marker		≤ 360°
X173	32, 33

225 ± 60°

internal zero marker

3.Pulse encoder type 2

Encoder with one pulse track per direction of rotation (with/without zero marker).

CW rotation CCW rotation

Track 1

X173 28, 29

Track 2

X173 30, 31

Zero marker

X173 32, 33

4.Pulse encoder type 3

Encoder with one pulse track and one output for direction of rotation (with/without zero marker).

CW rotation CCW rotation

Track 1		Pulse output
X173	28, 29
Track 2		Rot. direction
X173	30, 31
Zero marker		Zero marker
X173	32, 33
