Servo Resolver Daughter Board
Registration Input
The registration input is a 24v dc input connected through high-speed opto-isola-
tion into the resolver circuit. An alternative 5v input pin is available on the
encoder port. The internal circuitry can be used to capture the position at which
the registration input makes a transition from low to high or vice-versa. This
function is accessed in software from the REGIST command. The input is meas-
ured relative to the 0v input on the servo daughter board which must be con-
nected if the registration input is used. Note that this is the same 0v as the
resolver port.
Resolver Port Pinout
The reference oscillator runs at 2kHz and produces a +/- 2volt output.
The servo function can be switched on or off with the
SERVO axis parameter:
>>SERVO =ON
When the servo function is OFF the value in the axis parameter DAC is written to
the 12 bit digital to analog converter.
Therefore:
The measured position of the axis
MPOS is not reset to zero on power up but reset
to a value in the range 0-4095. All other software functions are similar to the
servo daughter board. The resolver converter circuit uses a fixed 12 bit conver-
sion. The motor resolution will therefore be 4096 “edges”/turn.
