3.3 Setting the rotation speed
The potentiometer P1 is used to adjust the rotation speed.
P1 at left stop: Minimum rotation speed
P1 at right stop: Maximum rotation speed
3.4 Setting the ramp slope and IxR compensation
Potentiometer: P2
Input: HE5
The function of potentiometer P2 is controlled via input HE5. If HE5 is open, the
ramp slope can be set. If HE5 is closed, the IxR compensation can be set. The
current set value for ramp slope and IxR compensation is stored when switching
HE5. When switching back input HE5, the value stored before is overwritten
with the current potentiometer setting.
Example: HE5 is open and you set the ramp slope with P2. After this HE5 is
closed to set the IxR compensation. Closing HE5, the set value for the ramp slope
is stored. Now you adjust the potentiometer to set the IxR compensation. If HE5
is opened now, the set value for the IxR compensation is stored and the value for
the ramp slope stored before is overwritten with the current potentiometer setting.
Setting the ramp slope
To set the ramp slope input HE5 must be open (logical 0). Then the
potentiometer P2 can be used to adjust the ramp slope for the starting/stopping
ramp.
P2 at left stop: steep ramp, starting/stopping time 0,1 sec.
P2 at right stop: flat ramp, starting/stopping time 5 sec.
Setting the IxR compensation
To set the IxR compensation input HE5 must be closed (logical 1). Then the
potentiometer P2 can be used to adjust the IxR compensation.
P2 at left stop: minimum compensation
P2 at right stop: maximum compensation
