Energy Savings Control
Fn82 and Fn83 provide energy savings for variable torque applications.
In variable torque applications the load is usually a high inertia load that
requires large starting torques but lower running torque.
Fn82 = Defines when and if energy savings capability is available. To monitor
energy savings change Fn47 = 0001 which will display output voltage
on keypad.
XX00: Energy savings disabled
XX01: Energy savings controlled by multi-input terminals only at set
frequency.
Enable energy savings mode through the multifunction input terminal
(TM2 pins 6 - 8). In this mode, if the multifunction input terminal is on
the output voltage will decrease gradually (to previous output voltage X
Fn83). When the input terminal is off, output voltage will go up to
previous voltage gradually. To program one of the multifunction input
terminals to an energy savings enable switch,
program Fn56 - Fn58 = 8 (N.O.) or 24 (N.C.).
Fn83 = Energy saving gain - Factory Setting = 80%; Range = 0 - 100%
Fn83 determines the gain (voltage level) at constant speed during energy
savings mode. Adjust Fn83 to a value that provides minimum motor
current draw at constant speed.
Process Time Parameters
Fn85-Fn91 define the process timer functions. These parameters are
only available if one of the multifunction digital input switches (SP1,
SP2 or SP3) is defined as a process timer initialization switch.
Fn 17 - Fn 23 = 0-400 Hz
Fn84 = Sequence Control - Factory Setting = 0000
XXX0: Process timer disabled
XXX1: Process timer enabled
XX0X: Set frequency output after process timer finishes counting
XX1X: Zero speed output after process timer finishes counting
Fn 85 - Fn 91 = Process timer 1 - Process timer 7 -
Factory Setting = 0 sec.; Range = 0 - 3600 sec:
There are two timer functions for which Fn17 - 23 are the preset speeds:
In the first timer function, if Fn84 = XXX1 and Fn56 to Fn60 = 0 - 2
(N.O.) or 16 -18 (N.C.) then this changes the multifunction input switches
from preset speed contacts to timer input contacts. When Fn84 =
XXX1 and Fn56 - Fn60 = 0 - 2 (N.O.) or 16 - 18 (N.C.) and a pulse
signal is received on the multifunction input, the drive will run at the
time specified by Fn85 - Fn91 at the frequency specified by Fn17-
Fn23. After the time has elapsed, the drive will return to the frequency
set by keypad, or external analog signal input, depending on the
programming of Fn11. (See Figure 5 - 10.)
In the second timer function, if Fn84 = XXX1 and Fn56 - 60 = 14 or 30,
then this changes the multifunction input to an automatic cycle
initialization contact. When the contact is momentarily made on TM2
the drive will go to the speed of Fn17 for time of Fn85, then will go to
speed of Fn18 for the time of Fn86. This continues through the seven
preset speeds of Fn17 - 23 for the seven preset times of Fn85 - 91.
After the timed cycle has elapsed the drive will return to frequency set
by keypad, or external analog signal input, depending on the
programming of Fn11. (See Figure 5 - 11.)
