U = UP (accelerating) status
D = DOWN (decelerating) status
H = HOLD (constant speed) status
U1 = UP status, clamping at upper limit speed
D1 = DOWN status, clamping at lower limit speed
Notes :
1. When UP/DOWN command is selected, the upper limit speed is set regardless of frequency
reference.
Upper limit speed = Max. output frequency (n09)
2. Lower limit value is either min. output frequency (n14) or max. output frequency (n09)
frequency reference lower limit (n31)/100% (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 command is input while running by the UP/DOWN command, the jog command
has priority.
5. Multi-step speed reference 1 to 3 is not effective when UP/DOWN command is selected.
Multi-step speed reference is effective during running in hold status.
6. When "1" is set for HOLD output frequency memory selection (n62), output frequency can
be recorded during HOLD.
Setting Setting
0 Output frequency is not recorded during HOLD.
When HOLD status is continued for 5 seconds or longer, the output
1
frequency during HOLD is recorded and the inverter restarts at
the recorded frequency.
