138 HX7+ ASD Installation and Operation Manual
Speed Loop Proportional Gain
Program Feedback Parameters PG Settings
This parameter sets the Proportional Gain (sensitivity) of the drive when
monitoring the PG signal to control speed. The larger the value entered here,
the more sensitive the drive is to changes in the received feedback and the
quicker it responds.
Direct Access Number — F376
Parameter Type — Numerical
Factory Default — (ASD dependent)
Changeable During Run — Ye s
Minimum — 3.2
Maximum — 1000
Speed Loop Integral Gain
Program Feedback Parameters PG Settings
This parameter sets the response time of the Speed Loop Integral Gain. The
smaller the value here, the more pronounced (quicker) the effect of the integral
function.
Direct Access Number — F377
Parameter Type — Numerical
Factory Default — (ASD dependent)
Changeable During Run — Ye s
Minimum — 10.0
Maximum — 200.0
Motor Counter Data
Program Feedback Parameters PG Settings
This parameter sets the pulses-per-revolution displayed at the Monitor screen
when using a shaft-mounted encoder for speed control. This setting is used for
display purposes only and does not affect the speed control of the system.
If zero is selected here then the setting at F370 (Electronic Gear Setting)
determines the pulses-per-revolution to be displayed at the Monitor screen.
Settings:
Selection 0 — F370 setting
Selection 1 — 256 pulses/revolution
Selection 2 — 512 pulses/revolution
Selection 3 — 1024 pulses/revolution
Selection 4 — 2048 pulses/revolution
Selection 5 — 4096 pulses/revolution
Direct Access Number — F378
Parameter Type — Selection List
Factory Default — Selection 0
Changeable During Run — No
Minimum — Selection 0
Maximum — Selection 5

parameter.
Direct Access Number — F379
Parameter Type — Numerical
Factory Default — 1.00
Changeable During Run — No
Minimum — 0.01
Maximum — 10.00
Use Speed Mode
Program Pattern Run Preset Speed Mode
This parameter Enables/Disables the Use Speed mode. When enabled, the
system uses all of the parameter settings of the Preset Speed being run.
Otherwise, only the frequency setting is used.
Settings:
0 — Disabled
1 — Enabled (box checked)
Direct Access Number — F380
Parameter Type — Check Box
Factory Default — Disabled
Changeable During Run — No
