• Reaction 1: dec ramp to fault
If value "1: dec ramp to fault" is selected, the drive changes into Fault reaction ac-
tive when the error occurs.
Bit 2 (fault reaction mode) in co32 state machine properties has the following ef-
fect:
• 0: direct => the drive changes immediately into state Fault. The control of
the power components is inactive in this state, the motor coasts down. The
adjustment of the pn parameters (fault or dec. ramp) is invalid
• 1: application specific => the behaviour of the drive for errors can be influ-
enced by the pn parameters if immediately switching off of the drive is not
required.
If "1: application specific" is selected as fault reaction mode , the setpoint speed is
set to the target speed (pn47) at the fault reaction ramp. After fault reaction time
the drive changes into state Fault. If an error reset is already carried out during
fault reaction, the drive changes into the state that results from st14 active control-
word.
• Reaction 2: quickstop
Bit 2 no Quickstop in active controlword (st14) is set to zero. The state machine
changes into the state Quickstop Reaction Active.
The selected reaction in 0x605A quickstop option code is executed.
The fault does not reset itself automatically. This means, only after reset (control-
word Bit 7 Fault reset) bit 2 is set again and the Quickstop reaction becomes inac-
tive.
The reaction becomes only effective, if in co32 state machine properties in mode
enable quickstop the setting "0200h: on“ is selected.
• Reaction 3: disable operation
Bit EnableOperation in active controlword (st14) is set to zero. The state machine
changes into state Disable Operation Active.
The selected reaction in 0x605C disable operation option code or co32 state ma-
chine properties is executed.
If the fault is no longer present, the EnableOperation Bit in active controlword
(st14) is set again according to the controlword internal (co31). An error reset is not
necessary.
