This parameter is used to set the end-of-travel range when using an encoder on
a motor-driven positioning system (e.g., hoist/crane, etc.).

PG Speed Frequency Setpoint #Utilities1
This parameter is used to set the direction, gain, and bias of the PG input when
the PG input is used as the Speed/Direction control input.
The PG input signal is a pulse train originating from a shaft-mounted Encoder.
Note:The PG input terminal is available with the ASD-Multicom
option board only.
PG Input Speed/Direction Control Setup
Perform the following setup to allow the system to receive Speed/Direction
control input at the PG input:
• Program
⇒ Utilitites ⇒ Command and Frequency Settings ⇒ Frequency
Mode#1 Select
⇒ Use Pulse Input.
• Program
⇒ Utilitites ⇒ Command and Frequency Settings ⇒ Command
Mode Select
⇒ (any setting).
• Provide a Run command (F and/or R).
Speed/Direction Control
Perform the following setup to allow the system to perform PG Speed/
Direction control:
• Set PG Speed Frequency #1,
• Set the PG input pulse count that represents PG Speed Frequency #1,
• Set PG Speed Frequency #2, and
• Set the PG input pulse count that represents PG Speed Frequency #2.
Once set, as the PG input pulse count changes, the directional information or
the output frequency of the ASD will vary in accordance with the above
settings.
This parameter sets the PG input pulse count that represents PG Speed
Frequency #1 (direction/speed). 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 Settings.
