the number of relubrications is set to 0.
the number of bearing changes is increased by 1.
10.7.18 Temperature sensor 1 (3.21)
This display is only shown if an MCB 114 sensor input module
has been installed.
Select the function of a Pt100/Pt1000 temperature sensor 1
connected to an MCB 114:
D-end bearing
ND-end bearing

Ambient temp.
Not active.
10.7.19 Temperature sensor 2 (3.22)
This display is only shown if an MCB 114 sensor input module
has been installed.
Select the function of a Pt100/Pt1000 temperature sensor 2
connected to an MCB 114:
D-end bearing

10.7.20 Standstill heating (3.23)
The standstill heating function can be set to these values:
Active
Not active.
When the function is set to Active and the pump is stopped by a

10.7.21 Ramps (3.24)
Set the time for each of the two ramps, ramp-up and ramp-down:
Factory setting:
Depending on power size.
The range of the ramp parameter:
1-3600 s.
The ramp-up time is the acceleration time from 0 rpm to the rated
motor speed. Choose a ramp-up time such that the output current
does not exceed the maximum current limit for the CUE.
The ramp-down time is the deceleration time from rated motor
speed to 0 rpm. Choose a ramp-down time such that no
overvoltage arises and such that the generated current does not
exceed the maximum current limit for the CUE.
