Inputs:
Program Enable, Output Enable, and Data Transfer Logic
of inputs determined by output option.
For P-type units:
Enable or TRUE:
11.0 to 28.0 VDC @ 13.5 mA max.
or tied to V
s+
Disable or FALSE: 2.0 VDC @ 0.2 mA max. or open circuit
For N-type units:
Enable or TRUE:
1.0 VDC @ -3.0 mA max. or tie to Vs-
Disable or FALSE: 3.8V DC to 28 VDC Max @ -0.2 mA max. or
open circuit
Data Transfer Input:
0-24 VDC logic:
Edge-triggered (i.e., data transfer on both
rising and falling edges)
Low-Level: 0 to 0.8 V @ 3.2 mA
High-Level: 2.4 V @ 0.4 mA
Minimum pulse width: 30 µs
Timing: Depends upon the PC sync option selected from
keyboard:
PC Synchronization mode: Updates position output within
150 µs of a transition edge (LOW-to-HIGH, or HIGH-to-LOW)
at data transfer input.
Transparent Mode/Microfreeze: Output data is
continuously updated at full speed. The data is latched for
100 µs ±10% within 10 µs of a transition (HIGH-to-LOW or
LOW-to-HIGH) at data transfer input.
