4.7.6 Synchronized Fastening Operation.
{ 1 SYNC: Bi-directional signal for synchronized fastening (5V, TTL signal).
P When synchronized 2 step fastening is used in multi-Axis arrays the connection of
the SYNC signals is in parallel and should be connected as shown below.
P Pins 6 & 7 and pins 8 & 9 are internally connected.
FIG. 4-7-6 Syncronizing Wiring Sample
From the start of the cycle until reaching 1st torque, the Axis SYNC signal is ON (LOW
condition) to stop other Axis from continuing to the second step (wired OR). When the 1st
torque is reached, the line works as an input signal. If it reads LOW - meaning that other Axis
units have not reached 1st torque yet - the Axis unit stays in the standby state. When the
SYNC signal is HIGH (all Axis units have completed the first step), all units simultaneously
start the second step.
