Speed measurement
The stored parameters in the encoder are divided in two groups: system and application parameter.
The data are different for synchronous motors (F5-S) and asynchronous motors (F5-M).
The following table gives an overview of the data:
F5-S F5-M

dr.24 DSM rated speed dr.01 DASM rated speed
dr.25 DSM rated frequency dr.02 DASM rated voltage

dr.27 DSM rated torque dr.04 DASM rated cos(phi)
dr.28 DSM curr. f. zero speed dr.05 DASM rated frequency
dr.30 DSM winding resistance dr.06 DASM stator resistance

Read data:
Each
encoder is clearly identified by an internal serial number.
If an inverter is connected the first time
with an encoder which contains an electronic name plate, this is auto-
matically read out, if „data load when switching on = 4: automatic “ is adjusted in Ec.38 (factory setting at F5-S).
No error is released if the reading is successful.
The data are not read out again as long as the encoder serial number does not change.
If another encoder (other serial number) is connected to the same inverter, error message „35: ERROR! enco-
der change“ (E.EncC) is
released first. Ec.37 „encoder 1
status“ displays the
value „96: new encoder identifier“.
If this error is reset, the inverter reads automatically the data of the new encoder (according to parameterizing)
and stores them.
If the encoder does not contain electronic rating plate data, „32: ERROR! encoder 1“ (E.Enc1) is released.
If the data shall be read later again from the encoder, this must be triggered manually by setting of bit 0 „reading
activated “in Ec.38.
Which data of the encoder shall be read can be selected with bit 3 and 4 „data group/ selection“.
In case of successful reading, bit „reading activated“ is automatically reset.
If the stored data cannot be read or loaded into the inverter, error message „32: ERROR! encoder 1“ (E.Enc1)
is released and parameter Ec.37 displays value 97: "invalid data".
Attention: The controller adaption is automatically triggered after read out of the data (corresponds to the set-
ting of Fr.10 = 2) and Pn.61 „absolute torque limit“ = cS.19 „absolute torque reference“ is set.
Data storage:
The data must be entered to the inverter if an encoder does not contain an electronic type plate. Next the data
can be stored in the encoder.
