Enable open, command value zero
Switch on mains supply
The motor must be at a torque-free standstill.
Close the drive enable switch
The LED ‘enable’ must light.
Turn the command value potentiometer slowly up.
The motor must accelerate according to the command value voltage.
(If the motor immediately accelerates to full speed or if full voltage is
immediately applying, the actual value connection across terminal 6-7
must be swapped).
Speed adjustment
Adjust the coarse actual value using the switch S3 (rf. to page 10).
When the command value is 1.2V adjust the speed to 10% by means of
the potentiometer n
max
(P2).
Adjust the min. speed by means of the potentiometer n
min
(P4).
Increase the command value to 12V and adjust the max. speed by
means of the potentiometer n
max
(P2).
Current adjustment
Connect an ammeter to the armature circuit.
Set the potentiometer I
max
to left full scale.
Disable the motor (disconnect the field).
Adjust the permissible motor current by turning the potentiometer I
max
(P6) clockwise.
Amplification speed controller
Basic set-up:
P-amplification
S2-3 = ON, S2-4 = OFF
I-term
S2-1 = ON, S2-2 = OFF
For large centrifugal masses switch S2-2 must be closed and switch S2-3 can
be opened.
If friction loads are predominant the switches S2-2 and S2-4 can be closed
and the switches S2-1 and S2-2 can be opened.
Exact adjustment by means of the potentiometer X
P
(P7).
Turn the potentiometer anti-clockwise until the LED RVU flickers.
Then turn it clockwise until the LED either lights constantly or is dark.
The brightness of the LED indicates the current demand of the drive.
