Continue at Last Speed with Alarm
For this condition, COMM FLG ENA (Point 90) must be enabled and CBL LOSS TMR (Point 91) should be set to something
other than 0. An AL14 Serial Communications Alarm is shown.
Continue at Preset Speed with Alarm
In this mode, CBL LOSS TMR (POINT 92) is set to the desired interval, CBL LOSS FRQ (POINT 91) 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’s speed command,
INPUT REF 1, (Point 60) is set to the CBL LOSS FRQ (POINT 91) and the drive continues running at this new speed. COMM
FLT ENA (POINT 90) must be set to ON.
Stop with Fault (FB14)
COMM FLT ENA (POINT 90) must be set to ‘On’. In this mode, CBL LOSS TMR (POINT 92) 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’s speed
command, INPUT REF 1, (Point 60) is set to 0. The stopping method is determined by the setting of F6-03. An FB14 drive
fault will be set and an EF0 will be sent to the drive. The drive behavior is determined by the setting of parameter 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 Fast Stop. The deceleration time is determined by the setting of drive parameter C1-09.
