Installing the 506/507/508 4-11506/507/508 - HA389427If the controller is in “Tacho” control then excess speed is due toincorrect polarity of feedback. Alter wiring as follows:-Problem ActionDirection correct but Reverse Tachogenerator polarity only.overspeeding.Direction incorrect andoverspeeding. Reverse field polarity only.If motor does not run, increase Ilimit potentiometer P4 as currentmay be insufficient for rotation. The Health light LED2 may light inthis condition after 15 seconds indicating a Stall, remove and reapplypower to reset condition.If the motor is in control but runs in the wrong direction either:-(a) Armature Control - Reverse Field Polarity.(b) Tacho Control - Reverse Field AND Tacho Polarity.3. Increase speed setpoint to maximum and check armature voltagedoes not exceed rated value, adjust maximum speed using P7. If aminimum speed setting is required reduce speed setpointpotentiometer to zero adjust minimum speed potentiometer P6 togive required value. With speed setpoint at maximum, re-adjustmaximum speed with P7.4. Adjust I Limit potentiometer to suit Motor Current Rating.508506 507(0.5)(1)(1.5) 3213.54 (2)5 (2.5)6(3) (1)(2)(3) 64278 (4)10 (5)12(6)(0.25)(0.5)(0.75)1.510.52 (1)2.5 (1.25)3(1.5)1.75More accurate adjustment may be achieved by inserting a meter inthe armature circuit.5. Adjust Ramp Up P1 and Ramp Down P2 potentiometers as required.6. In Armature Voltage Feedback, speed droop will occur as load isapplied. Adjust IR compensation P5 to reduce this effect. Excessiveadjustment may cause instability.7. It may be necessary to adjust the Speed Stability Potentiometer P3 toimprove speed response. Excessive adjustment may causeinstability.www.comoso.com
