If the "on" command (bit 0) is connected to the dual port RAM interface (Section 5.2.1 "Setpoint channel
(master to drive)"), then the following must be observed for safety reasons:
An "OFF2" or "OFF3" command must be additionally parameterized to the terminal strip/PMU (refer to the
drive Instruction Manual, Section "Control word"), as otherwise the converter cannot be powered-down with a
defined command if the communications were to fail!
♦ P692 (Response TLg OFF)
P692 is only used on the CU2.
Using parameter P692 (also refer to the drive Instruction Manual, Section "Parameter list") you can define as to
how the drive should respond to a telegram failure.
For a parameter value 0 "Fault" the drive immediately shuts down with fault F082, and the drive coasts down.
With parameter value 1 "OFF3(fast stop)", the drive executes an OFF3 command (OFF with fast stop) and then
goes into the fault status F082.
This parameter is only available from software version 1.3 (MASTER DRIVES CU1 and CU2) and software
version 1.2 (MASTER DRIVES CU3).
