Start-up

4. Start-up
After the installation or exchange of an encoder interface some adjustments of the inverter/
servo software have to be done before operation:
• Switch on inverter
• Select application mode
• When using synchronous motors set Ud.02 to F5-S
• Select parameter Ec.38; if automatic read in is not adjusted in Bit 2, read out encoder
data with Bit 0.
• At BiSS-C without electronic type plate, select and adjust parameter Ec.44 and Ec.53.
• Select parameter Ec.37 and control encoder status. Acknowledge possibly error mes-
sages.
4.1 Encoder 1 status (Ec.37)
This parameter displays, by means of different status messages, the status of encoder and
interface. All errors are only triggered at control release in inverter state ru.00, although they
are already displayed in Ec.37.
With Ec.42 can be adjusted if an error message of the encoder card triggers an error in the
inverter or not (ru.00).
Value Description
The following value is displayed at correct operation:
16 Position values are transferred, encoder and interface are working
The following status messages triggers „Error Encoder Change" (E.EnCC) because the
correct evaluation of the position is no longer guaranteed .
Error E.EnCC can only be reset via parameter Ec.00. Exception ! An error due to wrong
increments per revolution (value 70) is reset immediately, if the correct increments per
revolution are adjusted.
Attention, the modulation is released, when the control release is still set!
64 Encoder is unknown and will not be supported
66 No communication to the encoder. Initialization is not possible
67 Incremental signals invalid
68 Absolute signals are faulty. All signals are checked at TTL-encoders, at BiSS-C
and Endat the digital communication.
Difference to error 66:
The communication was o.k. before. Can also occur at BISS -C without el. type
plate: the connection to the encoder is o.k., but the setting of the data length
(Ec.44 and Ec.53) is still wrong. Error must be reset then.
