2.7 Error messages and error handling
2.7.21 Error message ’Current loop error’ (only MAC400 to MAC4500)
2.7.22 Error message ’Slave error’ (only MAC400 to MAC4500)
Message no. / Message
23 / ’Current loop error’
Type / Motor action Unrecoverable error / Motor is set in passive mode.
Error condition Error only relevant when using the MAC00-P5 module.
The 4-20mA input at the MAC00-P5 module has been detect-
ed lower than 2,0mA which is outside normal range.
Possible cause of this error
- Cable fault.
- Fault in the external 4-20mA source that feed the MAC00-P5
current input.
Solutions to avoid error - Check the cable feeding the 4-20mA input.
- Make sure that the 4-20mA signal stay at a level higher than
2,0mA.
How to return to normal
operation
- Reset the motor, clear the error bit(s) in register 35 or cycle
the 24VDC power.
Error bit / Firmware name Bit 22 / ’CURLOOP_ERR’
Message no. / Message
24 / ’Slave Error’
Type / Motor action Unrecoverable error / Motor is set in passive mode.
Error condition - Modbus communication with a slave motor has not been pos-
sible due to a communication error.
- A connected slave motor has discovered an error. See the
slave error register.
Possible cause of this error - The motor is setup as master but it has not been possible to
reach a slave motor.
- A connected slave motor has discovered an error. See the
slave error register.
Solutions to avoid error - If the actual system is a master/slave configuration make sure
that a slave motor is present.
- Make sure that the cabling is made in a proper manner with
twisted pair wires and screened cable.
- Make sure that the opposite unit in the communication sys-
tem uses same parameters such as baudrate etc.
How to return to normal
operation
- Reset the motor, clear the error bit(s) in register 35 or cycle
the 24VDC power.
Error bit / Firmware name Bit 23 / ’SLAVE_ERR’
