· Up/Down Command (setting: n040 = "Up/Down Control")
With the FWD (REV) run command entered, a change in frequency is
performed by inputting the Up or Down commands to control circuit
terminals S5 and S6, so that operation can be performed at the desired
speed. When the Down command is specified for terminal S6 by setting
n040="Up/Down Control", any function set to terminal S5 via parameter
n039 becomes disabled; terminal S5 becomes an input terminal for the
Up command and terminal S6 an input terminal for the Down command.

U: Up (accelerating) status
D: Down (decelerating) status
H: Hold (constant speed) status
UI: Up status, with clamping at upper limit speed
DI: Down status, with clamping at lower limit speed
Notes:
1) When the UP/DOWN command is selected, the upper limit speed is set regardless of fre-
quency reference.
Upper limit speed = Maximum output frequency (n011)
2) The lower limit value is either the analog frequency from control circuit terminals FV or
FI, or the frequency reference lower limit (n032), whichever is larger.
3) When the FWD (REV) run command is input, operation starts at the lower limit speed
without an UP/DOWN command.
4) If the jog frequency reference is input while the drive is running by the UP/DOWN
command, the jog frequency reference has priority.
