6 -158Using PG Speed Control BoardThere are four types of PG Speed Control Board that can be used in V/f control with PG.• PG-A2: A-phase (single) pulse input, compatible with open collector or complimentary outputs.• PG-B2: A/B-phase pulse input, compatible with complimentary outputs.• PG-D2: A-phase (single) pulse input, compatible with line drivers.• PG-X2: A/B/Z-phase pulse input, compatible with line drivers.There are two types of PG Speed Control Boards that can be used for flux vector control.• PG-B2: A/B phase pulse inputs, complementary outputs• PG-X2: A/B/Z phase pulse inputs, line driver outputsFor the connection diagram, refer to page 2-36 to 2-38.Setting Number of PG PulsesSet the number of PG (Pulse Generator/Encoder) pulses in pulses/rotation. Set the number of A-phase or B-phase pulses per 1 motor rotation in F1-01.Matching PG Rotation Direction and Motor Rotation DirectionConstant F1-05 matches the PG rotation direction and the motor rotation direction. If the motor is rotating for-wards, set whether it is A-phase driven or B-phase driven. Make this setting when using PG-B2 or PG-X2.Fig 6.78 PG Rotation Direction SettingGenerally, PG is A-phase driven when rotation is clockwise (CW) see from the input axis. Also, motor rota-tion is counter-clockwise (CCW) seen from the output side when Forward Commands are output. Conse-quently, when motor rotation is forward, PG is normally A-phase driven when a load is applied, and B-phasedriven when a load is not applied.InverterForwardCommandMotor PG (encoder)Pulse outputA-phase driven when set value = 0 B-phase driven when set value = 1A-phase A-phaseB-phase B-phaseExample: Forward rotation of standard Yaskawa motor (PG used: Samtack (KK))ForwardCommandMotor output axis rotatescounter-clockwise during In-verter Forward Command.Rotation(CCW)A-phaseB-phaseYaskawa standard PG used is A-phase driven (CCW) when motor rotation is forward.
