List Manual (LH8), 02/2015, 6RX1800-0ED76
A31461 (N)
Encoder 1: Analog sensor channel B failed
Message value:
%1
Message class:
Position/speed actual value incorrect or not available (11)
Drive object:
DC_CTRL, DC_CTRL_R, DC_CTRL_R_S, DC_CTRL_S
Reaction:
NONE
Acknowledge:
NONE
Cause:
The input voltage of the analog sensor is outside the permissible limits.
Alarm value (r2124, interpret decimal):
1: Input voltage outside detectable measuring range.
2: Input voltage outside the measuring range set in (p4675).
3: The absolute value of the input voltage has exceeded the range limit (p4676).
Remedy:
Re alarm value = 1:
- check the output voltage of the analog sensor.
Re alarm value = 2:
- check the voltage setting for each encoder period (p4675).
Re alarm value = 3:
- check the range limit setting and increase it if necessary (p4676).
Reaction upon N:
NONE
Acknowl. upon N:
NONE
A31462 (N)
Encoder 1: Analog sensor no channel active
Message value:
%1
Message class:
Error in the parameterization / configuration / commissioning procedure (18)
Drive object:
DC_CTRL, DC_CTRL_R, DC_CTRL_R_S, DC_CTRL_S
Reaction:
NONE
Acknowledge:
NONE
Cause:
Channel A and B are not activated for the analog sensor.
Remedy:
- activate channel A and/or channel B (p4670).
- check the encoder configuration (p0404.17).
Reaction upon N:
NONE
Acknowl. upon N:
NONE
A31463 (N)
Encoder 1: Analog sensor position value exceeds limit value
Message value:
%1
Message class:
Position/speed actual value incorrect or not available (11)
Drive object:
DC_CTRL, DC_CTRL_R, DC_CTRL_R_S, DC_CTRL_S
Reaction:
NONE
Acknowledge:
NONE
Cause:
The position value has exceeded the permissible range of -0.5 ... +0.5.
Alarm value (r2124, interpret decimal):
1: Position value from the LVDT sensor.
2: Position value from the encoder characteristic.
Remedy:
Re alarm value = 1:
- Check the LVDT ratio (p4678).
- check the reference signal connection at track B.
Re alarm value = 2:
- check the coefficients of the characteristic (p4663 ... p4666).
Reaction upon N:
NONE
Acknowl. upon N:
NONE
