This parameter is used to limit the rate that the output of the ASD may increase
for a given difference in the speed reference and the PID feedback value.

Feedback Settings
This parameter is used to limit the rate that the output of the ASD may decrease
for a given difference in the speed reference and the PID feedback value.

Feedback Settings
While operating in the PID mode, this parameter reads the feedback frequency.
Once the feedback frequency is within the setting of this parameter (
F374
)
relative to the commanded frequency, a properly configured output terminal is
activated.
Available output terminal settings for this parameter include:
FC = RR
,
FC =
RX
, and
FC = VI
(see
Table 13 on pg. 239
), where
FC
is the frequency
command and
RR
,
RX
, and
VI
are the input terminals of the received feedback.

PG Settings
This parameter is used to set the number of pulses output from a shaft-mounted
encoder that is used to indicate one revolution of rotation (360°) of the motor or
of the motor-driven equipment.
