Adjustment Directions
Mark 0 Potentiometer should be adjusted in accordance with specifications and applications
Marko Potentiometer should not be adjusted except in special cases
Do not tamper with following potentiometers as they have been set at the factory
• VR2 VR9 VR10 (For speed feedback adjustment)
• VR7 (For max motor current adjustment)
• VR1 3(For current offset adjustment)
