SOLDER BRIDGES
In this configuration, the drive must set with the following solder bridges and below internal setting:
Solder Bridges set for:
- Armature feedback
- Ramp time disabled
- Standard Dynamic constant
ADJUSTEMENT ZONE
Setting for Brush motor with armature
Note: On the adjustement zone are not considered
here the other components used to determine other
calibrations "for example. Calibration current rating
etc.".

RA resistor calculations
EXAMPLE: Brush DC motor with Ke= 26V/Krpm (Vdc)
Nominal speed N° =2000rpm
Risult: Vdc= 26*2000/1000= 52V
Drive model 65
Insert on base "RA" to adapt the system to use the motor voltage.
For the Example, risult Vdc=52V. The table shows a resistor with a value of 27Kohm.
Once the resistor RA is inserted, proceed with final speed adjustment.
Operate using trimmer SPEED on the front of the drive. With Clockwise Rotation the speed increases.
With Counter Clockwise Rotation the speed decreases. The Range of regulation is about +/- 25%.
