Using Uni-Polar Analog (A01.04 = 05):
If the system is using
Uni-Polar Analog
as the
Speed Control Method
, use the following formula to adjust
H03.03
(Gain Multiplier for Terminal A1 analog input signal)
or
H03.11 (Gain Multiplier for Terminal A2 analog input
signal)
:
Gain Terminal A1: H03.03 = (60 Hz x 100) / E01.04
or
Gain Terminal A2: H03.11 = (60 Hz x 100) / E01.04
1. Set
V/f Selection (E01.03) = 0F
to allow for setting a custom V/f pattern.
2. Ensure that the
Maximum Frequency (E01.04)
is increased from 60 Hz and will be equal to or slightly greater
than the maximum Swift-Lift Forward or Reverse speeds you want to run at.
a. Maximum frequency (E01.04)
≥
C06.02 and C06.03.
3. Set the terminal gain multiplier for H03.03 or H03.11. This is done so that the
maximum normal running speed
will be 60 Hz with the new E01.04 setting. Use one of the above equations to determine the correct multiplier.
a. For example, to set the gain for Terminal A1 if E01.04 is set to 80.0 Hz, then H03.03 = 75%
H03.03 = (60.0 Hz x 100%) / (80.0 Hz) = 75%
4. Set C06.01 = 01 or 02 to enable the
Swift-Lift Function
:
a. 01 = Enable Automatic.
b. 02 = Enable by Multi-Function Digital Input (MFDI).
5. Set C06.02 and C06.03 to determine
Swift-Lift
maximum FWD/REV output frequency.
6. Set C06.04 and C06.05 to determine
Swift-Lift
maximum enable output current.
7. Set the
Swift-Lift Enabling Speed (C06.06)
one or two hertz below the
maximum normal running speed
reference (see step 3).
a. For example: If the
maximum normal running speed
is at 60 Hz, set C06.06 to 58 or 59 Hz as the
Swift-Lift
Enabling Speed
.
