3-24 Programming and Parameters
Advanced Program Group (continued)
A105 [Comm Loss Action]
Related Parameter(s): P037, A106
Selects the drive’s response to a loss of the communication connection or excessive communication
errors.
Options 0 “Fault” (Default) Drive will fault on an F81 Comm Loss and coast to stop.
1 “Coast to Stop” Stops drive via coast to stop.
2 “Stop” Stops drive via P037 [Stop Mode]
setting.
3 “Continue Last Speed” Drive continues operating at communication commanded
speed saved in RAM.
A106 [Comm Loss Time]
Related Parameter(s): A105
Sets the time that the drive will remain in communication loss before implementing the option selected
in A105 [Comm Loss Action].
Values Default 5.0 Secs
Min/Max: 0.1/60.0 Secs
Display: 0.1 Secs
A107 [Comm Format]
Selects the protocol (RTU only), data bits (8 data bits only), parity (None, Even, Odd), and stop bits (1
stop bit only) used by the RS485 port on the drive.
Refer to Appendix C for details on using the drive communication features.
Important: Power to drive must be cycled before any changes will affect drive operation.
Options 0 “RTU 8-N-1” (Default)
1 “RTU 8-E-1”
2 “RTU 8-O-1”
A110 [0-10V Analog Input Low] Related Parameter(s): d020, P034, P038
Sets the analog input level that corresponds to P034 [Minimum Freq] if a 0-10V input is used by P038
[Speed Reference].
Analog inversion can be accomplished by setting this value larger than A111 [0-10V Analog Input
High].
Values Default 0.0%
Min/Max: 0.0/100.0%
Display: 0.1%
0
[Maximum Freq]
[Minimum Freq]
[0-10V Analog Input Low] [0-10V Analog Input High]
0
