Bit 00, Control not ready/ready
Bit 00 = ”0” means that the frequency converter
has switched off due to malfunction.
Bit 00 = ”1” means that the frequency converter
control is ready, but that there is not necessarily a
supply to the power unit present (in the case of
external 24 V supply of the control card).
Bit 02, Coasting/Enable
Bit 02 = ”0” means that the bit 03 of the control
word is ”0” (Coasting) or that the frequency con-
verter has tripped.
Bit 02 = ”1” means that the bit 03 of the control
word is ”1” and that the frequency converter has
not tripped.
The description of the other bits can be
found in the section ”status word according
to Profidrive”.

Bit 08, Activation of the fixed speed in
parameter 213
In the case of bit 08 = “0”, the fixed speed will not
be activated.
In the case of bit 08 = “1”, the motor runs at the
fixed speed.
Bit 09, Ramp selection 1/2
In the case of bit 09 = “0”, ramp 1 is active (para-
meter 207/208).
In the case of bit 09 = “1”, ramp 2 is active (para-
meter 209/210).
Bit 11, Relay 01
Bit 11 = “0”: Relay 01 is not activated.
Bit 11 = “1”: Relay 01 is activated, on the pre-con-
dition that control word bit was selected in para-
meter 323.
Bit 12, Relay 04
Bit 12 = “0”: Relay 04 is not activated.
Bit 12 = “1”: Relay 04 is activated, on the pre-con-
dition that control word bit was selected in para-
meter 326.
The description of the other bits can be
found in the section ”control word according
to Profidrive”.
