0: Forward run
1: Reverse run

0

Check the direction of rotation on the status monitor.

HTH

: Forward run   HTT : Reverse run ⇒ For monitoring,

see 8.1.

When the F and R terminals are used for switching between forward and reverse

rotation from the terminal board, the HT forward/reverse run selection is rendered

invalid.

Short across the F-CC terminals: forward rotation

Short across the R-CC terminals: reverse rotation

This function is valid only when EOQF is set to K (operation panel).

Setting acceleration/deceleration time

CEE : Acceleration time 1 (s)
FGE : Deceleration time 1 (s)

Set acceleration time from 0Hz operation frequency to maximum frequency HJ and deceleration
time as the time when operation frequency goes from maximum frequency HJ to 0Hz.

If the programmed value is shorter than the optimum acceleration/deceleration time determined
by load conditions, overcurrent stall or overvoltage stall function may make the
acceleration/deceleration time longer than the programmed time. If an even shorter
acceleration/deceleration time is programmed, there may be an overcurrent trip or overvoltage
trip for inverter protection. (For further details, see 13.1).

Function

1) For acceleration time CEE, program the time that it takes for the inverter output

frequency to go from 0Hz to maximum frequency HJ.

2) For deceleration time FGE, program the time that it takes for the inverter output

frequency to go from maximum frequency HJ to 0Hz.

Function

Program the direction of rotation when the running and stopping are made using the RUN
key and STOP key on the operation panel. Valid when EOQF (command mode) is set to
1 (operation panel).
