D.1Speedfbklossalarmaccordingtothetypeoffeedback
Note ! For the correct interpretation of the cause of the alarm trigger, it is necessary to transform the hex code indicated in pa-
rameter 17.29 SpdFbkLosscode, PAR 2172 , in the corresponding binary and verify in the encoder table that the active
bits and related description are used.
Example with encoder Endat:
PAR 2172 = A0H (hex value)
In the table “Speed fbk loss [22] alarm with absolute encoder EnDat” A0 is not indicated in the value column.
A0 should be contemplated as a bitword with meaning A0 -> 10100000 -> bit 5 and bit 7 . The following causes simulta-
neously intervene:
- Bit 5 = 20H Cause: the SSI signal interferences cause an error in the CKS or parity.
- Bit 7 = 20H Cause: The encoder has detected an incorrect operation and communicates it to the converter through the
Error bit. Bits 16..31 present the type of incorrect encoder operation detected.

Bit Value Name Description
0 0x01 CHA Cause:no impulses or disturbance on incremental channel A.
Solution:Check the connection of the encoder-drive channel A, check the connection of the screen, check the encoder
supply voltage, check parameter 2102 Encoder1supply, check parameter 2104 Encoderinputconfig.
1 0x02 CHB Cause:no impulses or disturbance on incremental channel B.
Solution:Check the connection of the encoder-drive channel B, check the connection of the screen, check the encoder
supply voltage, check parameter 2102 Encoder1supply, check parameter 2104 Encoderinputconfig.
2 0x04 CHZ Cause:no impulses or disturbance on incremental channel Z.
Solution:Check the connection of the encoder-drive channel Z, check the connection of the screen, check the encoder
supply voltage, check parameter 2102 Encoder1supply, check parameter 2104 Encoderinputconfig, check param-
eter 2110 Encoder1signalcheck
D.1.1ResetSpeedfbklossalarm
The reasons for activating the Speedfbkloss alarm and the information acquired by the encoder are shown in
parameter 2172 SpdFbkLosscode.
If no card has been installed the Speedfbkloss [22] alarm is generated and no cause is displayed in parameter
2172 SpdFbkLosscode. Several causes may be present at the same time.
If no card is recognised, the system runs a routine that always returns Speedfbkloss [22] active without specifying
a cause.
D.1.2Encodererroralarm
Setup is performed each time the drive is turned on, regardless of the regulation mode that has been selected. If an
error is detected during setup the Encodererror alarm is generated with the following codes:
Bit Value Name Description
8 0x100
Setup
error
Cause:An error occurred during setup. When this has been signalled the information obtained from the encoder is not
reliable.
Solution:Take the action recommended for Speedfbkloss [22] alarm according to the type of encoder.
9 0x200
Compa-
tibility
error
Cause:Firmware on option card incompatible with firmware on regulation card.
When this has been signalled the information obtained from the encoder is not reliable.
Solution:Contact Gefran in order to update the firmware on the optional card.
