J5 Limit Inputs (5-8 Axis)
The Brick Motion Controller limit and flag circuits give the flexibility to wire in standard 12V to 24V
limits and flags or wire in 5V level limits and flags on a channel basis. The default is set for the standard
12V to 24V inputs, but if the resistor pack is added to the circuit, the card can read 5V inputs.
Note:
J5 comes only with the 8-axis configuration.

If J5 is present and RP89 (limits 5), RP93 (limits 6), RP97 (limits 7) and RP101 (limits 8) are installed to the
unit, the voltage level of the flags can be lowered to 5V. User needs to specify these when ordering the unit.
RP89, RP93, RP97 and RP101 for 5V flags: 1Kohm Sip, 8-pin, four independent Resistors
RP89, RP93, RP97 and RP101 for 12-24Vflags: Empty bank. (Default)

Limit and Flag Circuit Wiring
The Brick Motion Controller allows the use of sinking or sourcing position limits and flags to the
controller. The opto-isolator IC used is a PS2705-4NEC-ND quad phototransistor output type. This IC
allows the current to flow from return to flag (sinking) or from flag to return (sourcing).
