6.5.4 ST OP M ODE RA MP / Live delay mode PIN 58
This is used when the drive must remain enabled during the period of time when the contactor drop out delay
timer is running. E. g. when an external force is trying to rotate the load and this is undesirable, or a final
shaft positioning routine is operating. See 6.10.9 ZERO INTERLOCKS / SPINDLE ORIENTA TE.
See also 6.10 CH A NGE PARA METERS / ZERO INTERLOCKS for details of other zero speed functions.
A change of this parameter during the drop-out delay time is not effected until the next contactor drop-out.
6.5.5 ST OP M ODE RA MP / Drop-out speed PIN 59
Note. If this parameter is set to 100 % then the drop out delay timer will commence with the STOP command
rather than waiting to reach a low speed. The level is symmetrical for forw ard and reverse rotation.
6.5.6 ST OP M ODE RA MP / Drop-out delay PIN 60
This function is normally used to prevent frequent contactor dropouts during jogging. It works by adding a
time delay to the function that tells the main contactor to de-energise. The timer is started w hen the motor
reaches 59)DROP-OUT SPEED threshold. If the drive is restarted before the contactor finally drops out then
the timer is reset, ready to start again.
If the RUN input goes low at any point during the stopping process, e ither heading for zero spe ed or during
the delay period, then the contactor wi ll drop out straight away.
During the timer sequence the drive loops are inhibited to prevent the motor from making small unwanted
movements. This can be over-ridden using 58)LIVE DELA Y MODE if the system is required to maintain po w er
while waiting for drop out. E. g. when an external force is trying to rotate the load and this is undesirable, or
a final shaft positioning routine is operating. See 6.10.9 ZERO INTERLOC KS / SPINDLE ORIENT A TE.
