Speed Loop Proportional Gain
Program Feedback 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 — Yes
Minimum — 3.2
Maximum — 1000
Speed Loop Integral Gain
Program Feedback 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 — Yes
Minimum — 0.1
Maximum — 200.0
Motor Counter Data Selection
Program Feedback 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:
0 — F370 setting
1 — 256 pulses/revolution
2 — 512 pulses/revolution
3 — 1024 pulses/revolution
4 — 2048 pulses/revolution
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
Speed Loop Parameter Ratio
Program Feedback PG Settings
Used for positioning control. Increases/decreases the ASD response time to the
received feedback.
Direct Access Number — F379
Parameter Type — Numerical
Factory Default — 1.00
Changeable During Run — No
Minimum — 0.01
Maximum — 10.00
Units — Seconds
Preset Speed Operation Mode
Program Frequency Preset Speed Modes
This parameter Enables/Disables the Speed Operation Mode when using a
preset speed. 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 (Use Frequency Command Only)
1 — Enabled (Use Direction, Acc/Dec, V/f, and Torque)
Direct Access Number — F380
Parameter Type — Selection List
Factory Default — Disabled
Changeable During Run — No
