Q9 ASD Installation and Operation Manual 119
PID Output Lower-Limit
Program Feedback Settings
Selecting Speed PID at parameter F359 allows for this parameter setting to
function as the Lower-Limit while operating in the PID Control mode.
Direct Access Number — F371
Parameter Type — Numerical
Factory Default — Lower-Limit (F013)
Changeable During Run — Yes
Minimum — Lower-Limit (F013)
Maximum — Upper-Limit (F012)
Units — Hz
Process Increasing Rate
Program Feedback Settings
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.
Direct Access Number — F372
Parameter Type — Numerical
Factory Default — 10.0
Changeable During Run — Yes
Minimum — 0.1
Maximum — 600.0
Units — Seconds
Process Decreasing Rate
Program 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.
Direct Access Number — F373
Parameter Type — Numerical
Factory Default — 10.0
Changeable During Run — Yes
Minimum — 0.1
Maximum — 600.0
Units — Seconds
Feedback Reach Detection Band
No Path — Direct Access Only
While operating in the PID mode, this parameter reads the feedback frequency
and when the frequency read is within F374 Hz of the frequency command a
properly configured output terminal is activated.
Available output terminal settings for this parameter include: FC = RR,
FC = RX, and FC = VI (see Table 7 on pg. 190).
Where FC is the frequency command and RR, RX, and VI are the input terminals
of the received feedback.
Direct Access Number — F374
Parameter Type — Numerical
Factory Default — 2.50
Changeable During Run — Yes
Minimum — 0.00
Maximum — Max. Freq. (F011)
Units — Hz
Number of PG Input Pulses
No Path — Direct Access Only
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.
Direct Access Number — F375
Parameter Type — Numerical
Factory Default — (ASD-Dependent)
Changeable During Run — No
Minimum — 12
Maximum — 9999
