Signal targets for STW1 in Interface Mode VIK-NAMUR (p2038 = 2)
Meaning
Signal
= ON (pulses can be enabled)
STW1.0
0 = OFF1 (braking with ramp-function generator, then pulse cancellation & ready for switching on)
1 = No OFF2 (enable is possible)
STW1.1
0 = OFF2 (immediate pulse suppression and switching on inhibited)
1 = No OFF3 (enable is possible)
STW1.2
0 = OFF3 (braking with the OFF3 ramp p1135, then pulse suppression and switching on inhibited)
1 = Enable operation (pulses can be enabled)
STW1.3
0 = Inhibit operation (cancel pulses)
1 = Operating condition (the ramp-function generator can be enabled)
STW1.4
0 = Inhibit ramp-function generator (set the ramp-function generator output to zero)
1 = Enable the ramp-function generator
STW1.5
0 = Stop the ramp-function generator (freeze the ramp-function generator output)
1 = Enable setpoint
STW1.6
0 = Inhibit setpoint (set the ramp-function generator input to zero)
STW1.7 = Acknowledge faults
STW1.8 Reserved
STW1.9 Reserved
STW1.10 1 = Control via PLC
STW1.11
1 = Dir of rot reversal
STW1.12 Reserved
STW1.13 Reserved
STW1.14 Reserved
STW1.15 1 = CDS selection
<1> Used in telegram 20.
<2> Bit 10 in STW1 must be set to ensure that the drive accepts the process data.
<3> Interconnection is not disabled.
