3-26 SA500 Drive Configuration and Programming
3.5 Feedback Registers (Registers 200-299/1200-1299)
The Feedback Registers view is used to configure the feedback registers that display
the current status of the drive. These registers are updated by the PMI and sent to the
UDC module over the fiber-optic link before every scan of the UDC task. The status of
these registers is retained after a Stop All.
Drive Status Register 200/1200
The bits in the Drive Status register indicate the current state of the drive. They reflect the status of the
activity initiated through the Drive Control Register (register 100/1100). All the bits in this register are written
to by the PMI.
Drive Enable Grant Bit 0
The PMI sets the Drive Enable Grant status
bit in response to the PMI_RUN@ command
after all of the interlock tests are passed to
indicate that the minor loop is running and
the motor is energized. Hex Value: 0001H

Resolver Alignment OK Bit 1
The PMI sets the Resolver Alignment OK bit
when the resolver alignment procedure has
been completed. This bit is turned off when
ALN_TST@ is turned off. If the tuning was
not successful, then WRN_TUN@ is set. Hex Value: 0002H

This bit is used only with a brushless motor.
Torque Reference In Positive Limit Bit 2
The PMI sets the Torque Reference In
Positive Limit bit if the motor has reached its
torque limit in forward rotation. When motor
torque drops below the positive torque limit,
the bit will be turned off. Hex Value: 0004H

Torque Reference In Negative Limit Bit 3
The PMI sets the Torque Reference In
Negative Limit bit if the motor has reached
its torque limit in reverse rotation. When
motor torque rises above the negative
torque limit, the bit will be turned off. Hex Value: 0008H
