78 GX9 ASD Installation and Operation Manual
Type Reset
Program Utilities
This feature assists the user when performing fault analysis or by allowing a
quick system setup change when required. Performing a Type Reset results in
one of the following user-selected post-Reset configurations.
Settings:
0 — None
1 — 50 Hz Setting
2 — 60 Hz Setting
3 — Reset to Factory Settings
4 — Clear Past Trips
5 — Clear Run Timer
6 — Initialize Typeform
7 — *Save User Settings
8 — Restore User Settings
9 — Reset EOI to Factory Settings
Note: User settings that are stored in the memory of the EOI are not
saved via the Save User Settings selection. The unsaved
functions include the EOI Option Setups, (Utilities
Display Parameters, and (Monitor Setup ) Scrolling
Monitor Select.
Direct Access Number — F007
Parameter Type — Selection List
Factory Default — None
Changeable During Run — No
Acceleration Time 1
Program Special Accel/Decel (1 – 4) Settings
This parameter specifies the time in seconds for the output of the ASD to go
from 0.0 Hz to the Maximum Frequency for the 1 Acceleration profile. The
Accel/Decel pattern may be set using F502. The minimum Accel/Decel time
may be set using F508.
Note: An acceleration time shorter than that which the load will allow
may cause nuisance tripping and mechanical stress to loads.
Automatic Accel/Decel, Stall, and Ridethrough settings may
lengthen the acceleration times.
Acceleration
The acceleration rate of a motor is determined by several factors: applied
power, applied load, and the physical properties of the motor (winding
parameters, motor size, etc.). The ASD will control the first of these factors:
input power. The settings of the ASD will control the frequency and amplitude
of the applied voltage to the motor.
Under most operating conditions, as the output frequency of the ASD goes up
so does the output voltage (linear acceleration). The ASD has the ability to
modify the relationship between frequency and voltage automatically to
produce smoother operation or increased (starting) torque (see F502).
