4-30 Daughter Boards
Differential Stepper Daughter Board
Trio Motion Technology
All outputs are RS422 differential lines without terminating resistors. A 26LS31
line driver is employed. The fault input and registration inputs are single
ended opto-isolated inputs that sink approximately 8mA.
WARNING:
The Fault input and Registration input are designed for 5volt operation. Apply-
ing 24 volts will damage the input circuit.
For 24 volt operation a 4k7 0.5Watt resistor must be added in series with the
input.
A 2 pin terminal connector is provided for the registration input.

Considerations
The differential daughter board uses the same axis gate array as a stepper
encoder daughter board as is therefore recognised by the Motion Coordinator
as this type (ATYPE=4). It does not however have an encoder inputs fitted so
may only be used in the VERIFY=OFF mode where the stepper pulses are fed
back into the encoder counter circuit.
