structure
6.01 Stop mode
Bit SP FI
Coding
Range 0 to 2
Default 1
Update rate Background read
Only one stopping phase exists and the ready state is entered as soon as the single stopping action is complete.It should be noted that the stop
condition is detected when the speed feedback is below the zero speed threshold (Pr 3.05) for at least 16ms. If the speed is not stable it is possible
that the stop condition is not detected. In this case the system should be made more stable or the zero speed threshold should be raised.
Stopping Mode
0: Coast
1: Ramp
2: No ramp
If coast stop is selected the inverter is inhibited immediately when the run command is removed. If however, hold zero speed is also selected (Pr 6.08
= 1), then the drive will be re-enabled to hold zero speed. The result is that the drive is disabled for one sample and then enabled to ramp the motor
to a stop. Therefore is coast stop is required Pr 6.08 should be set to zero to disable hold zero speed.
If stop with ramp is selected the relevant ramp rate is used to stop the motor even if Pr 2.02 is set to zero to disable ramps.
The motor can be stopped with position orientation after stopping. This mode is selected with the position controller mode (Pr 13.10). When this mode
is selected Pr 6.01 has no effect.
6.03 Mains loss ride through
Bit SP
Coding
1
Default 0
Update rate Background read
When this parameter is 1 then drive will try and ride through a mains loss. The length of time that the software can keep running after power loss will
depend of the AC level before the power is lost. On a 220V supply the ride through ability will be very short.
6.04 Start/stop logic select
Bit SP
Coding
Range 0 to 4
Default 4
Update rate Background read
This parameter is provided to allow the user to select several predefined digital input routing macros to control the sequencer. When a value between
0 and 3 is selected the drive processor continuously updates the destination parameters for digital I/O F2, F3 and F4, and the "enable sequencer
latching bit" (Pr 6.40). When a value of 4 is selected the destination parameters for these digital I/O and Pr 6.40 can be modified by the user. (Note
any changes made to the destination parameters only become active after a drive reset.)

Default 0
Update rate 4ms read
When this bit is set the drive remains active even when the run command has been removed and the motor has reached standstill. The drive goes to
the 'StoP' state instead of the 'rdy' state.
