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):
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.
Gain Terminal A1: H03.03 = (60 Hz x 100) / E01.04
Gain Terminal A2: H03.11 = (60 Hz x 100) / E01.04
