Explanation
1. S
1
: frequency command, S
2
: acceleration time, (Pr01-12) S
3
: deceleration time
(Pr01-13).
2. This command FREQ can control frequency command, acceleration time and
deceleration time of the AC motor drive. Special register control is shown as
following:
M1025: controls RUN (On)/STOP (Off) of the drive. (Run is valid when Servo
On (M1040 On).)
M1026: Operation directions FWD (On)/REV (Off) of the drive.
M1040: controls Servo On (On)/ Servo Off (Off).
M1042: enable quick stop(ON)/ disable quick stop(Off)
M1044: enable Stop (On)/ disable stop(Off)
M1052: frequency locked (On)/ disable frequency locked(Off)
3. S2, S3 : Acceleration and deceleration time setting. Its decimal point must
according to the Pr01-45 Time Unit for Acceleration/Deceleration and S Curve.
For example:
When Pr01-45=0 “Unit=0.01 sec”
The S2 of below Ladder diagram is set as 50 and it means acceleration is 0.5
second.
The S3 of below Ladder diagram is set as 60 and it means deceleration is 0.6
second.
4. WhenM11=Off, the drive frequency command will become 0Hz.
