4 = 2-Wire High-Speed: Outputs are kept in a ready-to-run state.
The drive will respond to a Start command within 10 ms. I/O
Terminal 01 (Stop) on the terminal block = coast to stop.
Important: There is greater potential voltage on the power output
terminals (U/TI, V/T2, W/T3) when using this option.
5 = RS485 Port: Remote communications. I/O Terminal 01 (Stop)
on terminal block = coast to stop.
The following describes some differences in operation of
commanding the drive via RS485 communications for different
firmware versions:
Important: When commanding jog via the RS485
communications port on drives with firmware version
1.04 or earlier, the jog command will follow the
commanded direction from I/O terminal 03. On
firmware version 1.05 and later, the commanded
direction will be provided via the RS485
communications port.
Important: When sending a continuous start command via the
RS485 communications port on drives with firmware
version 1.04 or earlier, a maintained stop input is
required to stop the drive. Once the stop input is
inactive, the drive will restart. On firmware versions
1.05 and later, once a stop input is received, the start
command must transition from high to low to high for
the drive to start.
!
ATTENTION: When P036 (Start Source) is set to
option 3, and the Run input is maintained, the Run
inputs do not need to be toggled after a Stop input
for the drive to run again. A Stop function is provided
only when the Stop input is active (open). Failure to
observe this precaution could result in severe bodily
injury.
