236802 <location>Hub: Time slice overflow
Message %1
value:
Drive object: A_INF, B_INF, HUB, S_INF, SERVO, TM41, VECTOR
Reaction: A_INFEED: OFF2 (NONE)
SERVO: NONE
VECTOR: NONE
Acknowledge: IMMEDIATELY (POWER ON)
Cause: A time slice overflow has occurred on the DRIVE-CLiQ Hub Module.
Fault value (r0949, interpret decimal):
xx: Time slice number xx
Remedy: - reduce the current controller frequency.
- carry out a POWER ON (power off/on) for all components.
- upgrade firmware to later version.
- contact the Hotline.
236804 <location>Hub: Checksum error
Message %1
value:
Drive object: All objects
Reaction: NONE
Acknowledge: NONE
Cause: A checksum error (CRC) occurred when the program memory on the DRIVE-CLiQ Hub Module was
read out.
Alarm value (r2124, interpret hexadecimal):
Difference between the checksum at POWER ON and the current checksum.
Remedy: - check whether the permissible ambient temperature for the component is maintained.
- Replace DRIVE-CLiQ Hub Module.
236805 <location>Hub: EEPROM checksum incorrect
Message %1
value:
Drive object: All objects
Reaction: NONE
Acknowledge: NONE
Cause: The internal parameter data on the DRIVE-CLiQ Hub Module are incorrect.
Alarm value (r2124, interpret hexadecimal):
01: EEPROM access error.
02: Too many blocks in the EEPROM.
Remedy: - check whether the permissible ambient temperature for the component is maintained.
- Replace DRIVE-CLiQ Hub Module.
236820 <location>Hub DRIVE-CLiQ: Telegram error
Message Component number: %1, fault cause: %2
value:
Drive object: All objects
Reaction: NONE
Acknowledge: IMMEDIATELY
Cause: DRIVE-CLiQ communication error from Control Unit to DRIVE-CLiQ Hub Module in question.
Fault value (r0949, interpret hexadecimal):
yyxx hex: yy = component number, xx = fault cause
xx = 01 hex = 1 dec:
Checksum error (CRC error).
xx = 02 hex = 2 dec:
Telegram is shorter than specified in the length byte or in the receive list.
