F-22 Avoidance Bandwidth

(continued)

Setting F-00 = 3 (multi-speed configuration) reconfigures the terminal strip control
inputs as follows:

Terminal 6 = START/STOP/IET RESET (open = STOP; closed = IET RESET/START)
Terminal 7 = MSPD 1
Terminal 8 = MSPD 0

Refer to section 5.2.

Terminals 7 and 8 are used to select the reference source as shown in table 8.1.

Example

Assume:

Minimum Speed (F-03) = 3 Hz
Maximum Speed (F-04) = 60.0 Hz
Avoidance Frequency (F-21) = 32.2 Hz
Avoidance Bandwidth (F-22) = 4 Hz
Avoidance Band = 30.2 to 34.2 Hz
