The encoder configuration can also be accessed in the menu [DRIVE DATA] (drC-) .
[CONFIG. ENCODER] (IEn-)
Code Name/Description Setting range Factory settings
IEn- [ENCODER CONFIG]
The encoder parameters can only be enabled if the encoder card has been inserted and the available selection options depend on the type of
encoder card.
EnS [Encoder type] [AABB] (AAbb)
These parameters can only be accessed if an incremental encoder card has been inserted.
To be configured according to the encoder type used.
AAbb [AABB] (AAbb) : For the signals A, A-, B, B-.
Ab [AB] (Ab) : For the signals A, B
A [A] (A) : For the signal A. The value is not accessible if [Encoder active] (EnU) = [Control] (rEG).
EnC [Encoder] [Not done] (nO)
Checks the encoder feedback ( see "Encoder testing" on page 157 )
This parameter can be accessed when an encoder card has been inserted and if [Encoder active] (EnU) is not [Dig reference] (PGr) .
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
If a fault is detected, the inverter is locked in fault mode
[Encoder fault]
(EnF) .
EnU [Encoder active] [No] (nO)
The parameter is accessible if an encoder card is present .
nO
[No]
(nO) : Function not active. In this case, access to the other parameters is not possible.
SEC [Security] (SEC) : The encoder is only for the monitoring as a speed feedback.
rEG [Control] (rEG) : The encoder indicates the actual speed value for control and monitoring purposes. This configuration is performed automatically
if the inverter is configured to run with closed control loop ( [Motor control type] (Ctt) = [FVC] (FUC) . If [motor control type] (Ctt) = [SVC U]
(UUC) , then the encoder runs in speed feedback mode and allows the static correction of the speed. This configuration is not available for other
values of
[Motor control type]
(Ctt) .
PGr [Reference] (PGr) : The encoder provides a reference. Can only be selected with an incremental encoder card.
PGI
[Number of pulses]
100 to 5000 1024
Number of pulses per encoder revolution.
These parameters can only be accessed if an incremental encoder card has been inserted.
PGA [Reference type] [Encoder] (EnC)
The parameter is accessible if [Encoder active] (EnU) = [reference] (PGr) .
EnC [Encoder] (EnC) : Use of an encoder.
PtG [Freq. Gene.] (PtG) : Use of a frequency generator (reference value without sign).
EIL [Min. freq. value] -300 to 300 kHz 0
The parameter is accessible if [Encoder active] (EnU) = [reference] (PGr) and if [Reference type] (PGA) = [Freq. Gene.] (PtG) .
The frequency is equal to the minimum speed.
EFr [Max. freq. value] 0 to 300 kHz 300 kHz
The parameter is accessible if [Encoder active] (EnU) = [reference] (PGr) and if [Reference type] (PGA) = [Freq. Gene.] (PtG) .
The frequency is equal to the maximum speed.
EFI [Filter Freq. Signal] 0 to 1000 ms 0
The parameter is accessible if [Encoder active] (EnU) = [reference] (PGr) .
Filtering of any faults.
