6) CLEAR signal output
This instruction can output the CLEAR signal after stopping at the origin.
If it is necessary to output the CLEAR signal at the completion of zero return, turn on the "CLEAR signal
output function enable" relay (see the following table).
Use an FX
output device.
a) If it is not necessary to use the CLEAR signal device specification function, or if an FX
b) If it is necessary to use the CLEAR signal device specification function:
7) Zero return speed
Use the devices shown in the following table to set the zero return speed. Be sure to set the zero return
speed so that the relation with the other speeds is "bias speed  zero return speed  maximum speed".
8) Creep speed
Use the devices shown in the following table to set the creep speed. Be sure to set the creep speed so
that the relation with the other speeds is "bias speed  creep speed  maximum speed".
