7.6.3 Max. error variable (outer dead band): set manually
The outer deadband determines the switching-on point of the actuator.
The motor starts if the actual value (input signal E2) or a change in nominal
value is higher than the max. error variable determined by the outer dead
band (refer to figure 9). Manual setting is only possible if the adaptive
behaviour (
ADAPTIVE BEHAVIOUR parameter) is switched off.

pre-determined time.

DEAD TIME (M1910)
Default value: 0.5 s
Setting range:
0.0 to 60.0 seconds
Information It must be ensured via the controls that the max. permissible number of
starts of the actuator is not exceeded. This can be achieved by setting the
dead time to a sufficiently high value.
