PG Num of Pulses
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.).
Parameter Type — Numerical
Factory Default — 500
Changeable During Run — No
Minimum — 1
Maximum — 9999
Units — Pulse Count

PG Input Phases
This setting determines if motor speed and direction will be conveyed by the
encoder.
Settings:
Single-Phase
Two-Phase
Parameter Type — Selection List
Factory Default — Two-Phase
Changeable During Run — No
PG Speed Frequency #1
Program

⇒
PG Speed Freq #1
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
⇒
Utility Group
⇒

(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.
