Motor Rotation Change
This parameter allows you to change the motor direction without changing the motor leads.
Table 5-6: Motor Rotation Parameter Settings
NOTE: To reverse the direction of rotation, program B03-04 = 1 (exchange phases), or
interchange any two motor leads (changing R/L1, S/L2, or T/L3 will not affect the shaft
rotation direction) as well as encoder phasing (F01-02 = 0/1 or swapping A and A
wires).
Zero-Speed Operation
This parameter sets the drive behavior when the frequency reference is below the Zero Speed level.
Table 5-7: Zero-Speed Operation Parameter Settings
Input Scan Time
B03-06 selects the microprocessor scan time for reading the status of the input control terminals. Set
B03-06 to “0” when a quicker response is needed from the control circuit terminal.
Table 5-8: Input Scan Time Parameter Settings
LO/RE Run Select
If the run reference/speed reference is switched between serial mode and drive terminal mode,
B03-07 determines action after the switch.
