Reg Name
35 ERR_BITS
Description: This register contains all information about present errors - if any.
Error bits:
Bit 0:
Bit 1:
Bit 2:
Bit 3:
Bit 4:
Bit 5:
Bit 6:
Bit 7:
Bit 8:
Bit 9:
Bit 10: Encoder Communication Error (Absolute Multi-turn Encoder option, H3).
Bit 11: SSI encoder.
Bit 12: Closed loop.
Bit 13: External memory.
Bit 14: Single turn encoder error (H2).
Bit 16: Zero search has timed out.
Bit 17: Control voltage (CVI) has been too low.
Bit 18: Motor driver overload (only available in SMC85/MIS34x/MIS43x).
Bit 27: STO_ALARM.
Bit 29: STO.
Important Bit 27 - Functional safety related !
The STO_ALARM will only be set if the STO self-diagnostic circuit has detected an inter-
nal error. In this case, the motor must be returned the manufacturer (JVL) for repair.
In general
If any of these bits are set, the motor is in a state of error, and will not move until all the
errors have been cleared.
Some of the errors can be cleared by writing zero to this register.
Other errors will require hardware fixes or intervention, such as allowing the motor
cool down or adjusting the power supply voltage.
