Continue at Preset Speed
CBL LOSS TMR (POINT 92) is set to the desired interval, CBL LOSS FRQ (POINT 91) is
set to the desired preset speed and F6-01 is set to 4 in this mode. The drive 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 If the time between messages exceeds the timeout interval. COMM
FLT ENA (POINT 90) must be set to ON.
Stop with Fault (BUS)
COMM FLT ENA (POINT 90) must be set to ON. CBL LOSS TMR (POINT 92) is set to the
desired interval and parameter F6-01 is set to a value of 0, 1, or 2 in this mode. The drive will
declare a BUS fault and drive’s speed command, INPUT REF 1, (Point 60) is set to 0 if the
time between messages exceeds the timeout interval. The stopping method is determined by
the setting of F6-01.
• F6-01=0 selects Ramp to Stop. The deceleration time or the slope of the ramp is determined
by the setting of drive
parameter C1-02.
• F6-01=1 selects Coast to Stop. The drive does not attempt to control the rate of deceleration.
• F6-01=2 selects Fast Stop. The deceleration time is determined by the setting of drive
parameter C1-09.
Note: The behavior of the drive at cable loss is controlled by parameter H5-04. This drive parameter works
with the points as described in the table above to determine how the drive will respond to a cable loss.
The drive will continue in its last state if running, the drive will continue to run at the last commanded
frequency if the cable loss fault is disabled.
u APOGEE FLN P1 Mailbox Function
n Reading a Drive Parameter
Two points are defined for reading any drive parameter:
• #70 Specifies the parameter to be read from the drive
• #71 Reports the value of the parameter specified in Point #70
The mailbox retrieves data from the parameter and sends it to the controller when this point
is read.
Example: Writing a value of 387 (183H) to Point #70 specifies drive parameter b1-04. Reading
Point #71 returns the current setting of parameter b1-04 to the controller.
n Writing to a Drive Parameter
Two points are defined for writing to any drive parameter:
• #72 Specifies the parameter to be written to
• #73 Entry location of the value to be written to the parameter specified in Point #72
