PG Opt Card
Err
SA-31 was set to 2 (Position
Synchronization Mode), but two PG-X3 or
PG-B3 option cards were not attached to
connectors CN5-B and CN5-C.
Connect the PG (PG) option cards to the
appropriate option card connectors. Select the
appropriate Position Synchronization mode
(SA-31).
SA-31 was set to 1, but one PG-X3 or
PG-B3 option card was not attached to
connector CN5-B.
FdEv Slave Pos Dev
The slave motor is locked. Check if the machine runs normally and if the
slave motor is locked.
Slave Dev Lvl (SA-46) is low. Increase the setting value of SA-46.
When Pos Accum Select (SA-39) is set to
1, the slave stops while the master encoder
is rotating. If the master encoder rotates even though the
slave is stopped by the application, set SA-39
to 0 (Only During Run).
The master input frequency is larger than
Maximum Output Frequency (E1-04) of the
slave. Set E1-04 to a value 10% larger than the
maximum input frequency of the master.
PL Loss of Position
The slave motor is locked. Check if the machine runs normally and if the
slave motor is locked.
When Pos Accum Select (SA-39) is set to
1, the slave stops while the master encoder
is rotating. If the master encoder rotates even though the
slave is stopped by the application, set SA-39
to 0 (Only During Run).
The set speed of the slave is too high for
the PPR of the encoder being used. Replace the encoder of the slave motor with a
low PPR type.
AF
Alignment Fault
Deviation between the master and slave
has exceeded the allowable amount
(SA-67). A fault has occurred or the trigger switches are
connected wrong.
There is a problem with the trigger switches
and/or wiring. Check if the trigger switches are connected and
whether or not the machine runs correctly.
