8.2 MIS23x Registers
8.2.61 Home_Bits
Description: Bit 0: Search for index
Bit 1: Change direction on limit.
Bit 2: Search for opposite side of sensor
Bit 3: Use Limit switch as sensor
Bit 4: Ignore switch (Used for searching only for index)
Contains configuration bits, that define how Zero Search should be carried out.
8.2.62 Setup_Bits
Description: These individual bits are used to control various functions in the firmware.
Bit 0: 1 = Invert motor direction.
Bit 1: 1 = Don’t start program after power up.
Bit 3,2: Select external encoder input format type.
0 = Disabled,
1 = Quadrature,
2 = Pulse/direction
Bit 4: 1 = Enable DSP 402 support / 0 (default) disables DSP402 support.
Bit 5: AutoEncoderSynchronize
1 = Synchronize to encoder after passive
Bit 6: InPhysPosMode
Bit 7: EncoderAout.
If set to 1, the I/O-6 pin will output the quadrature A signal from the internal
magnetic encoder, and not be available for normal digital I/O operation.
Bit 8: EncoderBout.
If set to 1, the I/O-7 pin will output the quadrature B signal from the internal
magnetic encoder, and not be available for normal digital I/O operation.
Bit 9: EncoderIout.
If set to 1, the I/O-8 pin will output the Index signal from the internal magnetic
encoder, and not be available for normal digital I/O operation.
Bit 10: EncoderToP_IST:
Activate the function that initializes both Register 10, P_IST, and register 16,
Encoder_Pos, to the value from register 46, AbsEncoderPos, at start up, in-
stead of initializing them to zero.
Bit 11: Multiturn.
Bit 12: KeepExtEncoder.
Do not zero the external encoder count in register 170, External_Encoder, on
startup, but use the value loaded from flash memory.
