Parameters for the encoder test
Code Name/Description Factory settings
EnC [Encoder] [Not done] (nO)
Check the encoder feedback. See process on the previous page.
The parameter is accessible if an encoder card is present
1)
.
nO [Not done] (nO) : Test not performed.
YES [Yes] (YES) : Activates monitoring of the encoder.
dOnE [done] (dOnE) : Test performed successfully.
The test procedure is used to check the following:
•
The direction of rotation of the encoder / motor
•
Existing signals (continuity of wiring)
•
Number of pulses/rotations
In the event of a fault, the inverter switches off with [Encoder fault] (EnF) .
EnU
[Encoder active] [No]
(nO)
The parameter is accessible if an encoder card is present
1)
.
nO [No] (nO) : Function not active.
SEC [Security] (SEC) : The encoder is only for the monitoring as a speed feedback.
rEG [Control] (rEG) : The encoder is used for the control and for the monitoring as a speed feedback. This configuration is performed automatically
if the inverter is configured with closed control loop (
[Motor control type]
(Ctt) =
[FVC]
(FUC) ). If
[motor control type]
(Ctt) =
[SVC U]
(UUC) ,
then the encoder acts as speed feedback and allows the static correction of the speed. For the other values of [motor control type] (Ctt) this
configuration cannot be accessed.
PGr [Reference] (PGr) : The encoder is used as reference. The choice is only possible with an incremental encoder card.
1) The access to the encoder-specific parameter is only possible if the encoder card is present. The available selection depends on the type of encoder card
used. The configuration of the encoder can also be accessed via the
[INPUTS/ OUTPUTS]
(I/O) menu.
