8.2 MIS23x Registers
8.2.24 Max_P_IST
Description: Position limit for movement in the positive direction. The motor can be configured
to stop automatically when it reaches this position.
8.2.25 Acc_Emerg
Description: The motor will use this acceleration during an emergency stop.
8.2.26 Err_Bits
Description: Error bits:
Bit 0: General error. Will always be set together with one of the other bits.
Bit 1: Follow error
Bit 2: Output driver error. Bit is set if one of the outputs is short circuited.
Bit 3: Position Limit error
Bit 4: Low bus voltage error
Bit 5: Over voltage error
Bit 6: Temperature too high (90°C)
Bit 7: Internal error (Self diagnostics failed)
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 reg-
ister. Other errors will require hardware fixes or intervention, such as allowing the
motor cool down or adjusting the power supply voltage.
