Cycle diagram

t1

Output stage enable via "FCB05 – fixed setpoints for positive direction of rotation"

t1 - t2

Motor runs up to the set minimum speed.

t2 - t3

Motor keeps minimum speed.

t3

"Motor potentiometer up" is activated.

t3 - t4

As long as the signal "Motor potentiometer up" is present, the motor speed is increased along the acceleration ramp (index 8377.21).

t4 - t5

If no signal is present any longer at "Motor potentiometer up", the actual speed is maintained.

t5

"Motor potentiometer up" is activated again.

t5 - t6

As long as the signal "Motor potentiometer up" is present, the motor speed is increased further along the acceleration ramp until it reaches the application limit (8357.10/11).

t6 - t7

The maximum speed is maintained, even if the signal at "Motor potentiometer up" is no longer present.

t7

"Motor potentiometer down" is activated.

t7 - t8

As long as the signal at "Motor potentiometer down" is present, the motor speed is decreased along the deceleration ramp (index 8377.31).

t8 - t9

If no signal is present any longer at "Motor potentiometer down", the actual speed is maintained.

t9 - t10

As long as the signal at "Motor potentiometer down" is present, the motor speed is decreased along the deceleration ramp (index 8377.31) until it reaches the minimum speed.

t10 - t11

The minimum speed is maintained.

t11

Revoking of the output stage inhibit via "FCB 05 – fixed setpoints, positive direction of rotation"
