4.7.6 Synchronized Fastening Operation (Without MULTI Unit)
Synchronized fastening allows spindles to synchronize at a preset torque before attempting
to reach the next target or final torque. For synchronized fastening operation using individu-
al SAN Units WITHOUT a Multi Unit, the SYNC terminals must be wired between all affected
spindles.
The SYNC signals are Bi-directional signals for synchronized fastening (5V, TTL signal).
with Pins 6 & 7 internally connected
1. At the start of the cycle until reaching the synchronization point (1st torque), the SAN
SYNC signal is ON (LOW condition) to stop other SAN Units from continuing to the sec-
ond step (wired OR).
2. When the 1st torque is reached, the signal works as an input signal. If it reads LOW -
meaning that other SAN units have not reached 1st torque yet - the SAN unit stays in the
standby state waiting for all connected spindles to reach first torque.
3. When the SYNC signal is HIGH (all SAN units have completed the first step), all units
simultaneously start the second step.
The figure below shows 2 ways for wiring the SYNC in a multi-spindle configuration.
NOTE: This wiring configuration is not the same as the AFC1100.
Connecting these signals with an AFC1100 cable could damage the input circuit!
