Configuring the Swift-Lift Function:
Using Multi-Step 2, 3, 5 (A01.04 = 00, 01, or 02):
If the system is using Multi-Step as the Speed Control Method, use the following instructions to
set up Swift-Lift.
1. Set V/f Selection (E01.03) = 0F to allow for a custom V/f pattern.
NOTE: Choosing a Custom V/f pattern will require setting of E01.01 ~ E01.13 parameters to
the current V/f selection. For additional V/f selections, see tables 5-5 and 5-6.
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.
Maximum frequency (E01.04) C06.02 and C06.03.
3. Set C06.01 = 01 or 02 to enable the Swift-Lift Function.
a. 01 = Enable Automatic
b. 02 = Enable by Multi-Function Input (MFI).
4. Set C06.02 and C06.03 to determine Swift-Lift maximum FWD/REV output frequency.
5. Set C06.04 and C06.05 to determine Swift-Lift maximum enable output current.
6. Set the Swift-Lift Enabling Speed (C06.06) one or two hertz below the maximum normal
running speed reference.
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.
Using Infinitely Variable 2, 3 Step (A01.04 = 03 or 04):
If the system is using 2-Step or 3-Step Infinitely Variable as the Speed Control Method, use the
following formula to adjust the constant B02.01 (Reference Upper Limit):
B02.01 = (60 Hz x 100) / E01.04
1. Set V/f Selection (E01.03) = 0F to allow for setting a custom V/f pattern.
NOTE: Choosing a Custom V/f pattern will require setting of E01.01 ~ E01.13 parameters to
the current V/f selection. For additional V/f selections, see tables 5-5 and 5-6.
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 Frequency Upper Limit (B02.01). This is done so that the maximum normal running
speed will be 60 Hz with the new E01.04 setting.
a. For example, if E01.04 is set to 75.0 Hz, then B02.01 = 80%
B02.01 = (60.0 Hz x 100%) / (75.0 Hz) = 80%
4. Set C06.01 = 01 or 02 to enable the Swift-Lift Function:
a. 01 = Enable Automatic.
b. 02 = Enable by Multi-Function Input (MFI).
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
