Fault condition/abnormal stop and restarting
After a drive fault condition or an abnormal stop, the drive can be restarted through
the controlling device by giving the following main command word bit sequence:
• Enable Bit 7 (Bit 7 = 1) to issue the fault reset command if the drive has tripped on
a fault.
• Disable Bit 3 (Bit 3 = 1 -> 0) to remove the drive start command. Else the drive will
not start, and the
warning will be displayed.
• Disable Bit 0 (Bit 0 = 1 -> 0), and then enable this bit (Bit 0 = 0 -> 1) again to make
the drive ready to accept the start command.
• Enable Bit 3 (Bit 3 = 1) to issue the start command.

The MSW values are shown in decimal and hex values (in brackets)
End Limit activation issues a OFF3 Command to the drive and therefore,
the drive behaves in the same manner as OFF3 command when End
limits are hit. Only difference here would be that the OFF3 Command
would automatically get enabled back when the reference polarity is
reversed.
Fast Stop activation issues a Normal Stop Command to the drive and
therefore, the drive behaves in the same manner as Drive Stop
Command when Fast Stop command is issued.
MCW corresponds to signal 09.06
(Main Control Word)
from the
PLC. MSW corresponds to signal 03.02 (Main Status Word). The
MCW and MSW values are shown in decimal and hex values (in
brackets).
End Limit activation issues an OFF3 command to the drive, and
therefore, the drive behaves in the same manner as the OFF3
command when the end limits are hit. The only difference is that
the OFF3 command will get automatically enabled again when
the reference polarity is reversed.
Fast stop activation issues a normal Stop command to the drive,
and therefore, the drive behaves in the same manner as the Stop
command when the Fast stop command is issued.
