Configuration of the incremental encoder
If you use an incremental encoder, configure it with the following CoE parameters:

Index | Name | Unit |
---|---|---|
8008:01hex | Invert feedback direction | - |
8008:02hex | Enable power supply | - |
8008:05hex | Enable ENC C input | - |
8008:11hex | mV | |
8008:12hex | - | |
8008:13hex | inc/rev |
8008:11 "Supply voltage output"
In this parameter, set the magnitude of the supply voltage for the encoder in millivolts. The value range is 2…24 V.
Switch on the supply voltage output by setting parameter 8008:02 "Enable power supply" to TRUE.
8008:12 "Encoder type"
In this parameter, set the signal type of the encoder.
An encoder must be connected if the value of this parameter is not "disabled". Otherwise, an error will be reported in the Diag History.
"HTL single ended" is set in the factory settings.
Signal type | Max. input frequency 1) | Current sink 2.5 mA | Signal level | Signal level | Comment |
---|---|---|---|---|---|
disabled |
| - | - | - | Incremental encoder interface disabled Is disabled by DM2 for Six-Step Hall |
RS422 differential | 5 million inc/s | no | Udiff < -0.45 V | Udiff > +0.45 V | - |
TTL single ended | 1 million inc/s | yes | < 0.8 V | > 3.0 V | - |
HTL differential | 5 million inc/s | no | Udiff < -2 V | Udiff > +2 V | - |
HTL single ended | 5 million inc/s | yes | < 6 V | > 9.2 V | - |
RS422 differential – high impedance input | 5 million inc/s | no | Udiff < -0.45 V | Udiff > +0.45 V | For applications in which the encoder signals are too weak |
TTL single ended – input filters disabled | 5 million inc/s | yes | < 0.8 V | > 3.0 V | Higher signal frequency possible. More sensitive to interference. |
Open collector | 250,000 inc/s | no | < 0.8 V | > 2.0 V | Encoder switches to ground |

8008:13 "Encoder Increments per Revolution"
Multiply the number of increments of the encoder by a factor of four. Enter the result in this parameter.
If you are using a magnetic encoder with interpolation, calculate the number of increments according to the following equation:

Example:
