Notes on operand usage: none

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 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)
M1025: Driver RUN (On) / STOP (Off), M1026: driver operating direction FWD (Off) / REV

(On). M1015: frequency reached.
When M10=On, sets the driver frequency command K300 (3.00 Hz), with an

acceleration/deceleration time of 0.
When M11=Off, the drive frequency command will now change to 0

Pr.09-33 are defined on the basis of whether the reference commands have been cleared

before PLC operation.
bit0: Prior to PLC scanning procedures, whether the target frequency has been cleared is
0. (This will be written to the FREQ command when the PLC is ON).

When M11=On, sets the driver frequency command K3000 (30.00 Hz), with an
acceleration time of 50 (0.5 sec.) and deceleration time of 60 (0.6 sec.). (When
