Setting 0: Ramp to stop (uses the deceleration time currently enabled)
Setting 1: Coast to stop
Setting 2: Fast Stop
Setting 3: Alarm only (continue operation)
Setting 4: Run at H5-14
This setting will trigger a “CE – Comm Loss” alarm and cause the drive to run at the speed set in H5-14 speed when a
Communication Error (CE) occurs.
The drive faults on CE and coasts to stop when H5-15 > 0 and the CE condition persists for the time set in H5-15.
Note the following conditions when using this setting and a CE occurs:
• During Pre-charge, the drive will continue to run at the Pre-charge frequency
• During Sleep, the drive will wake up and run at the speed set in H5-14
• During Feedback Drop, the drive will wake up an run at the speed set in H5-14
• Lag pumps are deactivated when in Contactor Multiplex.
