Notes on operand usage: none

S1
: Frequency command.
S2
: Acceleration time.
S3
: Deceleration time
 S2,S3: In acceleration/deceleration time settings, the number of decimal places is
determined by the definitions of Pr. 01-45.
Example
When Pr. 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 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 (3.00Hz), with an
acceleration / deceleration time of 0.
When M11=On, sets the drive frequency command K3000 (30.00Hz), 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 will now change to 0
