Incorrect Feedback Voltage
Calibration

Check Feedback Voltage Calibration Switches SW1/2.
Note These Switches must be set for both
Tachogenerator & Armature Voltage Feedback

Maximum Controller Output
Exceeded

Check compatibility of Motor Voltage to Controller
Output Voltage

Faulty Tachogenerator and/or
Coupling.

Check Tachogenerator (use Armature Voltage
Feedback Temporarily)

Motor runs at Full Speed
only

Incorrect Tachogenerator
Polarity or Open Circuit
Tachogenerator

Check Tachogenerator viability and connectivity

Open Circuit Speed Setpoint
Potentiometer

Check Terminal 13 or 10 as appropriate

Minimum Speed Setting

Check Minimum Speed Potentiometer P6

Motor runs with Zero
Setpoint.

Zero Speed Offset Adjustment Adjust P8 to give Zero Speed

Motor Speed

Stability P3
