• Ensure motor is disconnected from load. To assure safety, disconnect the coupling or
belt which connects the motor with the machine, so that motor operation is isolated
prior to test operation.
• Verify the encoder to be used meets the following criteria: Line driver type (8830,
88C30), output pulse levels of 5-12V, and quadrature (A+, A–, B+, B–). Power supply
for the encoder from the PG-X2 card is capable of 200mA @ 12VDC or 200mA @ 5VDC.
Do not use both of these power supplies simultaneously.
• Verify that the encoder PPR (pulses per revolution) and expected motor speed do not
exceed the bandwidth of the PG-X2 card, using the following formula:
300,000 Hz ≥ 1.2 x (Max Speed in RPM / 60) x PPR of encoder
NOTE: Speed in RPM = 120 x frequency / number of motor poles
Example: Encoder PPR = 1024, Maximum speed = 1750 RPM
