Dual Incremental Encoder

Faults and Alarms

The table below contains a list of encoder-specific faults and alarms, the type of

fault or alarm, the action taken when the drive faults, the parameter used to

configure the fault or alarm (if applicable), and a description and action (where

applicable).

xx000 Enc0 Open Wire Configurable P3

[Enc 0 FB Lss Cfg]

The dual encoder module has detected an encoder 0 input signal (A, B,

or Z) in the same state as its complement (A Not, B Not, or Z Not). For

open wire detection to work, the encoder signals must be differential

(not single ended). The Z channel is only checked when enabled. See P1

[Enc 0 Cfg].

xx001 Enc0 Phase Loss Configurable P3

[Enc 0 FB Lss Cfg]

More than 30 encoder 0 phase loss (open wire) events have occurred

over an 8 millisecond time period. The same restrictions as for Enc0

Open Wire detection apply.

xx002 Enc0 Quad Loss Configurable P3

[Enc 0 FB Lss Cfg]

Encoder 0 Quadrature loss events occur when simultaneous edge

transitions occur on both the A and B channels of encoder 0. This fault

will occur when more than 10 quad loss events over a 10 millisecond

time period are detected. Only valid when both A and B channels are

used (not Bit 1 “A Chan Only”) in P1 [Enc 0 Cfg].

xx030 Enc1 Open Wire Configurable P13

[Enc 1 FB Lss Cfg]

The dual encoder module has detected an encoder 1 input signal (A, B,

or Z) in the same state as its complement (A Not, B Not, or Z Not). For

open wire detection to work, the encoder signals must be differential

(not single ended). The Z channel is only checked when enabled. See

P11 [Enc 1 Cfg].

xx031 Enc1 Phase Loss Configurable P13

[Enc 1 FB Lss Cfg]

More than 30 encoder 1 phase loss (open wire) events have occurred

over an 8 millisecond time period. The same restrictions as for Enc1

Open Wire detection apply.

xx032 Enc1 Quad Loss Configurable P13

[Enc 1 FB Lss Cfg]

Encoder 1 Quadrature loss events occur when simultaneous edge

transitions occur on both the A and B channels of encoder 1. This fault

will occur when more than 10 quad loss events over a 10 millisecond

time period are detected. Only valid when both A and B channels are

used (not Bit 1 “A Chan Only”) in P11 [Enc 1 Cfg].

xx058 Module Defaulted Fault Coast Module was commanded to write default values.

(1) xx indicates the port number. Refer to Fault and Alarm Display Codes on page 312 for an explanation.
