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)
Example
1. M1025:
controls
RUN (On)/STOP (Off) of the drive. M1026: operation direction
FWD (On)/REV (Off) of the drive. M1015: frequency attained.
2. When M10=ON, setting frequency command of the AC motor drive to
K300(3.00Hz) and acceleration/deceleration time is 0.
3. When M11=ON, setting frequency command of the AC motor drive to
K3000(30.00Hz), acceleration time is 50 and deceleration time is 60.
