- Check
[Number of pulses]
(PGI)
and
[Encoder type]
(EnS).
- Check that the mechanical and electrical operation of the encoder, its power supply and connections are all correct.
- Reverse the direction of rotation of the motor (

(1) The encoder parameters can only be accessed if the encoder card has been inserted, and the available selections will depend
on the type of encoder card used. The encoder configuration can also be accessed in the
[1.5- INPUTS / OUTPUTS CFG]
(I/O)
menu.

Encoder feedback check See the procedure below.
The parameter can be accessed if an encoder card has been inserted (1).
-
[Not done]
(nO)
Check not performed.
-
[Yes]
(YES)
: Activates monitoring of the encoder.
-
[Done]
(dOnE)
: Check performed successfully.
The check procedure checks:
- The direction of rotation of the encoder/motor
- The presence of signals (wiring continuity)
- The number of pulses/revolution
If a fault is detected, the drive locks in
[Encoder fault]
(EnF)
fault mode.

: Function inactive
-
[Fdbk monit.]
(SEC)
: The encoder provides speed feedback for monitoring only.
-

(rEG)
: The encoder provides speed feedback for regulation and monitoring. If
[Motor control

(Ctt)
=
[SVC U]

the encoder operates in speed feedback mode and enables static correction of
the speed to be performed. This configuration is not accessible for other
[Motor control type]

values.
-
[Speed ref.]
(PGr)
: The encoder provides a reference.
