Synchro Input.
No connection.
Bandwidth. Logic 1 for high BW (53 Hz); logic 0 for low BW (13 Hz).
Control Transformer Set. Logic 1 for normal tracking logic 0 for CT operation. Used when AC error (e)
is needed to drive external control loop by the difference angle of the resolver input and the digital
input and for presetting the converter to a specific angle to reduce the step response time.
Resolution Control A. Change Resolution to 10, 12, 14, or 16 bit depending on logic level (See TABLE 3).
Resolution Control B. Change Resolution to 10, 12, 14, or 16 bit depending on logic level (See TABLE 3).
Inhibit. Logic 0 prevents digital output bits from changing.
Enable MSBs. Logic 0 enables digital output bits 1-8. Logic 1 disables these bits.
Enable LSBs. Logic 0 enables digital output bits 9-16. Logic 1 disables these bits.
Digital Output Bit 1 (MSB all modes).
Digital Output Bit 2.
Digital Output Bit 3.
Digital Output Bit 4.
Digital Output Bit 5.
Digital Output Bit 6.
Digital Output Bit 7.
Digital Output Bit 8.
Digital Output Bit 9.
Digital Output Bit 10 (LSB-10 BIT MODE).
Digital Output Bit 11.
Digital Output Bit 12 (LSB-12 BIT MODE).
Digital Output Bit 13.
Digital Output Bit 14 (LSB-14 BIT MODE).
Digital Output Bit 15.
Digital Output Bit 16 (LSB-16 BIT MODE).
Loss of signal. Used for system safety; the LOS output changes from logic 0 to 1 if all three synchro
inputs are disconnected.
Built-ln-Test. Monitors level of error (D) and will change to logic 0 if it exceeds approximately 65 bits .
Also logic 0 for an over-velocity condition.
Converter Busy. Indicates digital output update.
Direction. Logic 1 to count up; logic 0 to count down.
Major Carry. Used for turns counting applications; normally high goes low for all 1 ‘s when
counting up or all 0’s when counting down.
Supply Voltage.
Ground.
Supply Voltage.
Velocity Programming. Increase output scale factor with external resistor (R) from VEL PROG (pin 37)
to ground.
Velocity. DC voltage proportional to angular velocity.
AC Error. Used in CT mode; e is proportional to the difference between the resolver input angle
θ and
the digital output angle
φ (θ - φ).
AC Reference Input. Used to drive internal demodulator.
