232811 <location>Encoder 2: Encoder serial number changed
Message -
value:
Drive object: All objects
Reaction: A_INFEED: OFF2 (NONE)
SERVO: OFF1 (NONE, OFF2, OFF3)
VECTOR: OFF1 (NONE, OFF2, OFF3)
Acknowledge: IMMEDIATELY
Cause: The encoder serial number has changed. The change is only checked for encoders with serial number
(e.g. EnDat encoders).
Cause:
The encoder was replaced.
Note:
With closed-loop position control, the serial number is accepted when starting the adjustment (p2507
= 2).
When the encoder is adjusted (p2507 = 3), the serial number is checked for changes and if required,
the adjustment is reset (p2507 = 1).
Remedy: Mechanically adjust the encoder. Accept the new serial number with p0440 = 1.
232812 <location>Encoder 2: Requested cycle or RX-/TX timing not supported
Message %1
value:
Drive object: All objects
Reaction: OFF2
Acknowledge: IMMEDIATELY
Cause: A cycle requested from the Control Unit or RX/TX timing is not supported.
Alarm value (r2124, interpret decimal):
0: Application cycle is not supported.
1: DQ cycle is not supported.
2: Distance between RX and TX instants in time too low.
3: TX instant in time too early.
Remedy:
232813 <location>Encoder 2: Hardware logic unit failed
Message Fault cause: %1 bin
value:
Drive object: SERVO, VECTOR
Reaction: OFF1 (IASC/DCBRAKE, NONE, OFF2, OFF3)
Acknowledge: PULSE INHIBIT
Cause: The DRIVE-CLiQ encoder fault word supplies fault bits that have been set.
Fault value (r0949, interpret binary):
Bit 0: ALU watchdog has responded.
Bit 1: ALU has detected a sign-of-life error.
Remedy: Replace encoder
232820 <location>Encoder 2 DRIVE-CLiQ: Telegram error
Message Component number: %1, fault cause: %2
value:
Drive object: All objects
Reaction: A_INFEED: OFF2
SERVO: OFF1 (IASC/DCBRAKE, NONE, OFF2, OFF3)
VECTOR: OFF1 (IASC/DCBRAKE, NONE, OFF2, OFF3)
Acknowledge: IMMEDIATELY
