122 GX9 ASD Installation and Operation Manual
PG Reference Point 1
Program Frequency Speed Reference Setpoints
This parameter is used to set the gain and bias of the PG input of the option
board when a shaft-mounted encoder is used as the control input while
operating in the Speed Control mode.
Note: See Instruction Manual D/N 58687 for more information on the
PG Option Board.
PG Speed Control Setup
Perform the following setup to allow the system to receive Speed control input
at the PG input:
•Program Fundamental Standard Mode Selection Frequency Mode
1 Pulse Input (option).
•Program Fundamental Standard Mode Selection Command Mode
Selection (Application-Specific).
•Set PG Input Point 1 Frequency (F235).
• Set the PG input value (F234) that represents PG Reference Point 1.
•Set PG Input Point 2 Frequency (F237).
• Set the PG input value (F236) that represents PG Reference Point 2.
•Provide a Run command (F and/or R).
Once set, as the PG input pulse count rate changes, the output frequency of the
ASD will vary in accordance with the above settings.
This parameter sets the PG input pulse count that represents Reference
Setpoint 1 (frequency). The range of values for this parameter is -100% to
100% of the PG input pulse count range.
Note: Further application-specific PG settings may be performed from
the following path: Program Feedback PG Settings

Frequency Settings
PG Input Point 1 Frequency
Program Frequency Speed Reference Setpoints
This parameter is used to set the speed of the PG input when the PG input is
used as the control input.
This parameter sets PG Input Point 1 Frequency and is the frequency that is
associated with the setting of PG Reference Point 1.
See PG Reference Point 1 (F234) for further information on this setting.
Direct Access Number — F235
Parameter Type — Numerical
Factory Default — 0.0
Changeable During Run — Yes
Minimum — -Max. Freq. (F011)
Maximum — Max. Freq. (F011)
Units — Hz
PG Reference Point 2
Program Frequency Speed Reference Setpoints
This parameter is used to set the direction and speed of the PG input when the
PG input is used as the control input.
This parameter sets the PG input signal that is associated with PG Input Point
2 Frequency.
This value is entered as -100% to +100% of the PG input signal range.
See PG Reference Point 1 (F234) for further information on this setting.
