FREQ, FREQP: 7 steps
Operands:
S1: frequency command, S2: acceleration time, S3: deceleration time
Explanation:
1. This command can control frequency command, acceleration time and deceleration time
of the AC motor drive. Please use M1025 to RUN(ON)/STOP(OFF) the AC motor drive
and use M1025 to control the operation direction: FWD(ON)/REV(OFF).
Program Example:
1. M1025: RUN(ON)/STOP(Off) the AC motor drive. M1026: operation direction of the AC
motor drive – FWD(OFF)/REV(ON). M1015: frequency is reached.
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.
