■ bUS Error Auto-Reset
bUS Error Auto-Reset Function Description
bUS Error Auto-Reset when configured, allows the drive to automatically recover from a
bUS error as a result of a communication loss with the host.
A bUS Error will automatically reset under the following conditions.
• Network communication between the host and the drive is restored. (bUS error removed)
• bUS Error Auto-Reset is enabled as described in this section.
Enabling bUS Error Auto-Reset
Parameter F6-14 <1> bUS Error Auto Reset enables the bUS Error Auto-Reset function. F6-
14 becomes available when the option is installed on the drive.
1. Set parameter F6-14 = 1:Enabled
2. Set parameter F6-01 = 0:Ramp to Stop, 1:Coast to Stop, 2:Fast-Stop
3. Set parameter F7-16 = 0.1 to 10.0 seconds (optional)
Enabling bUS Error Auto-Restart (After a Time Delay)
Parameter F7-16 Communication Loss Timeout will delay the occurance of a bUS error
condition by the amount of time set in this parameter. F7-16 is set in tenths of seconds. The
status LEDs on the option will indicate the bUS error condition immediately upon detection
and during the F7-16 delay time. Refer to Figure 52 .
• Set parameter F7-16 = 0.1 to 10.0 seconds (0.0 setting disables F7-16) to enable timeout
delay.
