S : Frequency command. S

S
,S3: In the acceleration and deceleration time settings, the number of decimal
2
places is determined by the definition in Pr.01-45.
Example
When Pr.01-45 = 0: units of 0.01 sec.
A setting of S = 50 (acceleration time) in the ladder diagram below implies 0.5
2
sec., and the S (deceleration time) setting of 60 implies 0.6 sec..

The FREQ command can control drive Frequency commands, and acceleration
and deceleration time. It also uses special register control actions, such as:
M1025: Control drive RUN(ON)/STOP(OFF) (RUN requires Servo On (M1040 ON)
to be effective)
M1026: Control drive operating direction FWD(OFF)/REV(ON)
M1040: Control Servo On/Servo Off.
M1042: Trigger Quick Stop (ON)/does not trigger Quick Stop (OFF).
M1044: Pause (ON)/release pause (OFF)
M1052: Lock frequency (ON)/release lock frequency (OFF)
M1025: Drive RUN (ON)/STOP (OFF), M1026: drive operating direction FWD
(OFF)/REV (ON). M1015: frequency reached.
When M10 = ON, sets the drive frequency command K300 (3.00 Hz) with an
acceleration and deceleration time of 0.
When M11 = ON, sets the drive frequency command K3000 (30.00 Hz), with an
acceleration time of 50 (0.5 sec.) and deceleration time of 60 (0.6 sec.) (when
Pr.01-45 = 0).
When M11 = OFF, the drive frequency command changes to 30 Hz.
