

S2,S3: In acceleration/deceleration time settings, the number of decimal places is
determined by the definitions of Pr01-45.
Example
When 01-45=0: units of 0.01 sec.
The setting of 50 for S2 (acceleration time) in the ladder diagram below implies 0.5 sec,
and the S3 (deceleration time) setting of 60 implies 0.6 sec

The FREQ command can control driver frequency commands, and acceleration and
deceleration time; it also uses special register control actions, such as:
M1025: Control driver RUN(On)/STOP(Off) (RUN requires Servo On (M1040 On) to be
effective)
M1026: Control driver 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)
44.
M1025:
FWD(Off)/REV(On). M1015: frequency reached.
45.
When M10=On, sets the driver frequency command K300(3.00Hz), with an
acceleration/deceleration time of 0.
When M11=On, sets the driver frequency command K3000 (30.00Hz), with an
acceleration time of 50 (0.5 sec.) and deceleration time of 60 (0.6 sec.). (When 01-45=0)
46.
When M11=Off, the driver frequency command will now change to 0
