NOTE: Each byte consists of 8 bits, but the frequency converter uses only the last 4 bits.
VLT Control Commands
The four control and status bytes are used to send control
commands to the VLT adjustable frequency drive when the
telegram is sent from the master, and to send status from
the VLT to the master when the telegram is returned from
the VLT. When these four bytes are used for control, they
have the following meaning:
OFF 1: Makes a normal ramp stop of the motor and
opens the relay output of the VLT (relay off).
OFF 2: Makes a motor coast and opens the relay output
(relay off)
OFF 3: Same as OFF 1, but the motor makes a
quick-stop.
Bit 10: This bit has to be 1, if any of the control commands
should cause a reaction.
