Instruction manual

6. DRIVE MODULE
6 − 28
(6) Operation mode when error occurs
The operation method when major errors occur at the output modules of a
given system can be designated as shown below.
Control occurs as shown below, based on the parameter settings (see Table
6.4) of the synchronous encoder which is connected to the synchronous
encoder main shaft.
(a) Continuation ....... Output module operation continues even if a major output
module error occurs. The error detection signal
(M2407+20n) will switch ON at such times, and the
corresponding error code will be recorded at the major error
storage area.
The system and output module continuation/stop setting
when a major output module error occurs is designated in
the sequence program.
(b) Clutch OFF......... When a major output module error occurs, that system's
clutch will be switched OFF and all connected output
modules will stop. At this time, the clutch ON/OFF command
device will not switch OFF, but the clutch status storage
device will switch OFF regardless of the clutch ON/OFF
command device's ON/OFF status.
Operation will continue at axes where no clutch is connected.
The drive module can be stopped from the sequence pro-
gram, if required. To resume operation, eliminate the error
cause, then switch the clutch ON/OFF command device ON.
