PG Settings
This parameter sets the degree and rate at which the output frequency will be
allowed to change when prompted by changes in the output current.
The larger the value entered here, the quicker/more the drive responds to
changes in feedback.
Direct Access Number — F375
Parameter Type — Numerical
Factory Default — (ASD-dependent)
Changeable During Run — No
Minimum — 100.0
Maximum — 1250
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 — Yes
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 — Yes
Minimum — 10.0
Maximum — 200.0

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 —
