Forward run when F-CC closed (default); reverse run when R-CC
closed (default); reverse run when both closed (default); coast-stop
when ST-CC opened (default); emergency coast stop by a
command from operating panel or terminal block; 3-wire control and
motorized speed pot programmable functions.
Jog run from panel with JOG mode selection. Terminal
block operation possible with parameter settings.
Set frequency plus 15 preset speeds possible with combinations of
CC, SS1, SS2, SS3, and SS4 (default functions).
When a protective function is activated, the system checks main
circuit devices, and attempts to restart. Settable to a maximum
of 10 times; wait time adjustment (0 to 10 secs)
Automatic load reduction during overload (Default setting: OFF).
A coasting motor can be smoothly restarted (Default setting: OFF).
4 groups of 8 patterns each can be set to the 15 preset speed values.
A maximum of 32 different patterns can be run; terminal block
control/repetitive run possible.
Braking starting frequency adjustment (0 to 120Hz), braking current
adjustment (0 to 100%), braking time adjustment (0 to 10secs),
