Drive Behavior at Loss of Communication
The drive can be configured to respond to an interval without receipt of a message in one of
the following methods:
• Continue at last speed
• Continue at last speed with alarm
• Continue at preset speed
• Ramp to Stop with EF0 fault
• Coast to Stop with EF0 fault
• Emergency Stop with EF0 fault

Metasys N2 I/O
Three Metasys N2 outputs are used to select the desired behavior:
• AO 21 -Cable Loss Timeout
• AO 22 -Cable Loss Speed
• BO 11 -Communication Fault

Not all drives support setting F6-01=4.
Note:
1. Communication must first be established and then lost for these features to function as described. A
communications timeout does not occur if a drive is powered-up without a cable connected or with
the master controller offline.
2. A run command must have been issued (BO 1=ON or BO 2=ON) prior to loss of communications
for modes that describe the drive running after a communications timeout. The drive will not
automatically restart from a stopped condition for safety purposes. Additional external wiring is
required (consult factory) if a user requires the drive to restart automatically.
A BUS fault will be declared and will remain until communication is restored upon expiration
of the communications timeout interval.
