Procedure for Using Forced Interrupt

The following timing chart illustrates interrupt feeding under direct operation,
using the X axis as an example. There is a movement of 10,000 pulses in the
direction of travel.

FORCED INTERRUPT is a command which is only enabled during memory
operation. It is used for taking emergency evasive action from the current opera-
tion under memory operation.
When a sequence number with the forced interrupt operation set is specified and
the FORCED INTERRUPT Bit is turned ON, the pulse output of the memory
operation currently being executed is stopped (without deceleration) and posi-
tioning is executed from the specified sequence number. There is no need to
turn ON the Sequence Number Enable Bit.
1. Set the forced interrupt action in the positioning sequence and transfer it to
the Position Control Unit.
2. When a forced interrupt is required, specify the sequence number set in (1)
and FORCED INTERRUPT from OFF to ON.
