Instruction manual

6. DRIVE MODULE

6 − 4

(5) 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

6.1) of the virtual servo motor which is connected to the virtual 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.
