Code Error message shown
on the display [on the
integrated keypad]
Sub-code Description
100H-256 Cause: An error occurred during setup; the information received from the encoder is not reliable. If the encoder is used for feedback the
Speed fbk loss [22] alarm is also generated.
Solution: Take the recommended action for the Speed fbk loss [22] alarm.
200H-512 Cause: The firmware on the optional encoder card is incompatible with that on the regulation card. The information received from the
encoder is not reliable
Solution: Contact Gefran in order to update the firmware on the optional encoder card.
51 Opt cfg change [OCFG]
Condition: an optional card has been removed with respect to the configuration present when the last Save parameters command was executed or there
is a fault on the optional card or on the regulation card.
Solution: If the user has removed the card on purpose, execute Save parameters. If the user has not removed the card, identify and replace the faulty
card.
52 Power config [PCFG]
Condition: It can occur at the power-on during recognition size phase.
Solution: Contact the Gefran technical support centre.

Plc16 fault [PL16]
Condition: Enabled application developed in the IEC 61131-3 environment has found the conditions for generating this specific alarm to be true. The
meaning of the alarm depends on the type of application. For more information, refer to the documentation concerning the specific application.
XXXXH-X The XXXXH-X code indicates the reason for the error: make a note of this to discuss it with the service centre.
Solution: Refer to the documentation concerning the enabled application.
10.2 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 parameter 17.38 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 simultaneously occours:
- Bit 5 = 20H Cause: the SSI signal interferences cause an error in the CKS or parity.
- Bit 7 = 80H 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.
The value is displayed in hexadecimal format on the optional and standard keypad.

● Speed fbk loss [22] alarm with digital incremental encoder
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 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 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 supply, check parameter 2104 Encoder input config, check parameter 2110 Encoder signal check
