The following conditions must be true for the main contactor to be energised.
1) All alarms A ND supply synchronisation healthy. ( 699)RE ADY FLAG ).
2) CSTOP at 24V. Note. The CSTOP must be high for at least 50mS prior to START going high.
3) Start OR Jog high.
When the contactor has energised, the drive will run if
RUN input is high AND if enabled, the ZERO INTERLO CK is satisfied.
The contactor will de-energise after approximately 100 milliseconds if
699)RE A DY FLA G goes lo w OR CSTOP goes lo w
If the zero interlock is enabled and requests a non-run action, then the contactor will energise for
approximately 2 seconds but no current will flo w. The contactor will drop out if the zero reference interlock
condition is not satisfied within approximately 2 seconds. The display wi ll show C ONTA CTOR LO CK OUT.
The contactor will de-energise if ST ART and JOG are both low. In this case the time taken for the contactor
to de-energise depends on the ST OP MO DE RA MP when stopping from a running mode, or JOG/SLA C K
RA MP when stopping from a jog mode.

6.5.1.3 Contactor drop out
If ST ART or JOG goes high during the 60)DROP-OUT DELA Y time, then the contactor stays energised and
the drive will restart immediately. The 60)DROP-OUT DELAY timer will be reset to time zero. This allo ws
jogging without the contactor dropping in and out.
