6.2.3 Signal Operation and Functions (Cont'd)
Note 1: Related parameters: Parameters described below become effective when parameter
18 b4 = 1, ineffective when b4 = O.

Note 2: When DEC signal is at H level in mode I and AST signal is activated, operation
is started at approach speed (parameter 52) from the beginning, regardless of
zero-point return feed speed (parameter 51).
