4.3 Adjusting the potentiometers
4.3.1 Pre-adjustment
With pre-adjustment, the potentiometers are set in a preferred position.
Units in the original packing are already pre-set.

4.3.2 Adjustment
1.
Apply max. set value (10 V or 3.9 V) and turn potentiometer P1 n
max
until
required max. speed is reached.
Encoder operation
DC tacho operation
Voltage regulator
IxR compensation
2.
Adjust potentiometer P4 I
max
to required limit value.
Limited current in the 0…2 A range can be adjusted in linear fashion with
the
P4 potentiometer.
Important: The limit value I
max
should be below the nominal current
(max. permissible continuous current) as per motor data sheet.
3.
Slowly increase potentiometer P5 gain until the gain is set sufficiently
high.
Important: If the motor is unsteady, vibrates or makes noises, the
selected amplification is too high.
4.
Apply 0 V set value and adjust the motor to speed 0 rpm with
potentiometer
P3 Offset .
Important: DIP switch S9 must be set in the “ON
Ð
” position for offset
adjustment.
Applicable to IxR compensation only:
5.
Slowly increase potentiometer P2 IxR until compensation is set
sufficiently high so that the motor speed does not drop or only drops very
slightly at higher motor load.
Important: If the motor is unsteady, vibrates or makes noises, the
selected compensation is too high.
Current regulator
1.
Adjust potentiometer P4 I
max
to required limit value.
Limited current in the 0…2 A range can be adjusted in linear fashion with
the
P4 potentiometer.
Important: The limit value I
max
should be below the nominal current
(max. permissible continuous current) as per motor data sheet.
2.
Apply 0 V set value and adjust the motor to current 0 A with
potentiometer
P3 Offset .
Important: DIP switch S9 must be set in the “ON
Ð
” position for offset
adjustment.
Note:
•
DIP switch
S10
in position:
“ON
Ð
”: Set value range -3.9 ... +3.9 V equivalent to approx. -2 ... +2 A
motor current
“OFF
Ï
”: Set value range -10 ... +10 V equivalent to approx. -2 ... +2 A
motor current
•
In current regulator operation, potentiometers P1 n
max
, P2 IxR and P5 gain
are not active.
