Function: Internally Set Speed Selection 1
Pin 6 is the Internally Set Speed Selection 1 Input (VSEL1) in Internal Speed Control Mode (when
Pn02 is set to 1).
Four speeds can be selected by using pin 6 in combination with the Internally Set Speed Selection
2 Input (VSEL2).
Reverse Drive Prohibit/Forward Drive Prohibit Input
Pin 7: Reverse Drive Prohibit Input (NOT)
Pin 8: Forward Drive Prohibit Input (POT)
Functions
These inputs prohibit forward and reverse operation (overtravel).
When an input is ON, operation is possible in that direction.
These inputs can be disabled using the setting of Drive Prohibit Input Selection (Pn04).
The motor will stop according to the setting of the Stop Selection for Drive Prohibition Input (Pn66).
