Continue at Last Speed with Alarm
For this condition, Communication Fault Enable (BO 11) must be enabled and Cable Loss Speed (AO 22) should be set to a
value other than 0. An AL14 Serial Communications Alarm is shown.
Continue at Preset Speed with Alarm
In this mode, Cable Loss Timeout (AO 21) is set to the desired interval, Cable Loss Speed (AO 22) is set to the desired preset
speed and Z3–05 is set to "4". If the time between messages exceeds the timeout interval, the drive speed command (AO 1)
is set to the Cable Loss Speed (AO 22) and the drive continues running at this new speed. Communication Fault Enable (BO
11) must be set to 'On'.
Stop with Fault (FB14)
Communication Fault Enable (BO 11) must be set to 'On'. In this mode, Cable Loss Timeout (AO 21) is set to the desired
interval and parameter F6-03 is set to a value of 0,1 or 2. If the time between messages exceeds the timeout interval, the drive
will declare an EF0 fault and the drive speed command (AO 1) will be set to 0. The stopping method is determined by the
setting of F6-03.
• F6-03 = 0 selects Ramp to Stop. The deceleration time or the slope of the ramp is determined by the setting of drive parameter
C1-02
• F6-03 = 1 selects Coast to Stop. The drive does not attempt to control the rate of deceleration.
• F6-03 = 2 selects Emergency or Fast Stop. The deceleration time is determined by the setting of drive parameter C1-09.
