Acc-24E2 Limit and Flag Wiring

The Acc-24E2 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 photo-transistor output type. This IC allows the current to
flow from return to flag (sinking) or from flag to return (sourcing).

A sample of the positive limit circuit is shown below. The 4.7K resistor packs used will allow 12-24V
flag inputs. If 0-5V flags are used, then a 1K

Ω

resistor pack (RP) can be placed in either RP45 or RP46

(refer to the Resistor Pack Configuration section of this manual). If these resistor packs are not added, all
flags (

±

Limits, Home, User, and amplifier fault) will be referenced from 0-5V.

Connecting Limits/Flags to the Acc-24E2

The following diagram illustrates the sinking and sourcing connections to an Acc-24E2. This example
uses 12-24V flags.
