Operating conditions
do not exist
The "in operation [IOP]" checkback signal was
missing when a traversing command was
initiated. The following causes inhibit the "in
operation" checkback signal (status bit No.2,
refer to function diagram sheet 200) :
-Control signals [OFF1], [OFF2], [OFF3]
and/or "enable controller" [ENC] are not
activated.
-Checkback signals [OFF2] and/or [OFF3] are
not activated.
-A fault [FAULT] is active.
Effect:
The traversing command is inhibited.
Activate control signals [OFF1], [OFF2],
[OFF3] and "enable controller" [ENC].
-If checkback signals [OFF2] and/or [OFF3]
are missing, check the supply of control word
1 (MASTERDRIVES function diagram, sheet
180).
-Analyze the queued fault number
[FAULT_NO], remedy the fault, and then
cancel the fault using the acknowledge fault
[ACK_F] control signal.
Note:
To activate the "in operation" [IOP] status
again, you must deactivate [OFF1] and then
activate it again.
