Setting of the feedback system for position and speed control
Absolute value encoder as position and speed encoder
6
l
146 EDBCSXP064 EN 8.0
An absolute value encoder mounted on the motor shaft can be used without an additional
resolver as position and speed encoder.
1. Select absolute value encoder for position and speed control.
– Single−turn encoder: C0490 and C0495 = 3
– Multi−turn encoder: C0490 and C0495 = 4
If X8 has been selected as output by changing C0491, X8 will be automatically reset to
input through the encoder selection.
)
Note!
If an encoder (TTL, SinCos, absolute value encoder) is used, for C0490 and
C0495 only identical settings are permissible.
2. Select an absolute value encoder.
– Single−turn encoder: C0419 = 307 ... 311
– Multi−turn encoder: C0419 = 407 ... 411
The encoder data (C0420, C0421, C0427) are set automatically in accordance with the
selection.

Danger!
When absolute value encoders are used, uncontrolled movements of the drive
are possible!
With operating systems up to and including version 6.7, the drive may start up
in an uncontrolled manner with high speed and high torque after mains
connection and controller enable.
Possible consequences:
ƒ Death or severe injuries
ƒ Destruction or damage of the machine/drive
Protective measures:
ƒ Do not parameterise the codes C0420, C0421 and C0427!
3. Set the encoder mounting position.
– C3001 = 0: normal (same direction of rotation as direction of rotation of motor)
– C3001 = 1: inverse (opposite direction of rotation to direction of rotation of motor)
4. Save settings with C0003 = 1.
