3.4.2 Encoders
One of four types of encoder may be connected to the XE connector (high
density 15-pole socket, fitted on device), see the table 3.4.2.2 for the jumper
settings
- DE: 5V digital incremental encoder with
A/A,B/B,C/C
- SE: 5V sinusoidal incremental encoder with
A/A,B/B,C/C
- DEHS: 5V digital incremental encoder with
A/A,B/B,C/C
and three Hall
sensor digital position signals (for AC Brushless motors special software
required - contact your sales representative)
- SESC: 5V sinusoidal incremental encoder with
A/A,B/B,C/C
and and
two sin/cos traces for absolute position (for AC Brushless motors or
positioning - contact your sales representative)
- SEHS: 5V sinusoidal incremental encoder with
A/A,B/B,C/C
and three
Hall sensor digital position signals (for AC Brushless motors special sofware
required - contact your sales representative)
Encoders are used to feedback a speed signal to the regulator. The encoder
should be coupled to the motor shaft with a backlash free connection.
Optimal regulation results are ensured when using sinusoidal encoders. Digital
encoders (rotary encoders) may also be used. See section 2.3.6, “Performance”.
The encoder cable can be made of twisted pairs with a global shield, which
connect to ground on the Drive side. Avoid connecting the shield on the motor
side. In particular cases where the cable length is more than 328 feet (100
meters), (high electromagnetic noise), it may useful to use a cable with a shield
on each conductor pair, which can be connected to the common point (0V). The
global shield must always be grounded. Some types of sinusoidal encoders
may require installation with galvanic isolation from the motor frame and shaft.

Jumper S17 selects the reading or the ignoting of the channel C pulses. It must
be set correctly in order to detect the encoder loss alarm.
S17 ON : channel C (index) monitoring=ON
S17 OFF: channel C (index) monitoring=OFF
(*) If the encoder is not provided of the zero channel : S17=OFF
