Warning
• This output (transistor) turns off, when the
detector detects an alarm.
• The function differs depending on the control
mode.
• Used to release the motor electromagnetic brake.
• Use "Output (transistor) ON" to release the electromagnetic brake.
• See Timing Charts (App. 10 -13).
• Signal which is selected at Pr09 (warning output selection)
will be turned on. This output (transistor) turns ON at least
for one second after warning indication signals are output.

"In-torque limiting" output
Output(transistor) turns ON during the In-toque limiting.
Zero speed output
Output(transistor) turns ON when the motor speed becomes
lower than that of the preset speed with Pr61(Zero speed).
Output of both over-regeneration and overload warnings
Output(transistor) turns ON when either one of over-
regeneration or overload is activated.
Over-regeneration warning output
Output(transistor) turns ON when the over-regeneration
(more than 85% of permissible power of the internal
regenerative discharge resistor) warning is activated.
Overload warning output
O u t p u t ( t r a n s i s t o r ) t u r n s O N w h e n t h e o v e r l o a d ( t h e
effective torque is more than 85% of the overload trip
level) warning is activated.
Does not function, although displayed.

control
• In-position output
• Output(transistor) turns ON when the position error is below the
preset value by Pr60 (In-Position Range).
• At-speed.
• This output (transistor) turns ON, when the motor speed exceeds
the preset value by Pr62 (At-Speed).
