3.2.23 Control of the drive controller (DCTRL)
3−61
l
EDSVS9332S−EXT EN 2.0
3.2.23.6 Parameter set changeover (PAR)
The controller loads and operates with the parameter set selected.
l The parameter set to be loaded is selected via the inputs DCTRL−PAR*1 and DCTRL−PAR*2.
The inputs are binary coded (1 from 4).
PAR*2 PAR*1 Selected parameter set
0 0 Parameter set 1
0 1 Parameter set 2
1 0 Parameter set 3
1 1 Parameter set 4
l A LOW−HIGH edge at the input DCTRL−PAR−LOAD enables the controller to switch to the new
parameter set.
)
Note!
If the parameter set to be loaded via the terminal X5/Ex is already selected before
switching on the supply voltage, there is no need for the LOW−HIGH edge at the
input DCTRL−PAR−LOAD. In this case, the controller loads the selected parameter
set automatically.
l The controller is not ready for operation for approx. one second. During this period, DCTRL−
RDY displays LOW.
3.2.23.7 Controller state
The binary−coded status of the controller is output via DCTRL−STAT*x. These outputs are connected
to the STAT function block inside the device.
The status can be evaluated via the status word C0150, CAN status word and AIF status word.
STAT*8 STAT*4 STAT*2 STAT*1 Action of the controller
0 0 0 0 Initialisation after the supply voltage has been connected
0 0 0 1 Lock mode, restart protection is active C0142
0 0 1 1 Drive is in controller inhibit mode
0 1 1 0 Controller enabled
0 1 1 1 The release of a monitoring function resulted in a "message"
1 0 0 0 The release of a monitoring function resulted in a "trip"
3.2.23.8 Standstill message (DCTRL−NACT=0)
The standstill message (DCTRL−NACT=0) is set immediately if the actual speed (MCTRL−NACT) falls
below the speed threshold (without any hysteresis effect) set in C0019.
The standstill message disappears if the actual speed (MCTRL−NACT) exceeds the sum of the speed
threshold set in C0019 and the hysteresis. The hysteresis amounts to 1 % of the maximum speed
set in C0011.
)
Note!
The hysteresis ensures a stable standstill signal even if the actual speed value jitters.
