The output frequency of AC motor drive (0.00–600.00)
RO
D1050 Actual operating mode (speed mode = 0)
RO
Speed mode control command:
FREQ(P) S1 S2 S3
Target speed 1
st
acceleration time 1
st
deceleration time
The example for speed mode control:
Before executing speed control, if the control method is FOC (magnetic field orientation), you have to
set up the motor parameters to be used first.
1. Set D1060 = 0, to make the AC motor drive be speed mode (default).
2. Control frequency, acceleration time and deceleration time by FREQ instruction.
3. Set M1040 =1, AC motor drive is being magnetized, but the frequency is zero.
4. Set M1025 = 1, the frequency command of AC motor drive becomes the frequency that FREQ
instruction designates. The acceleration and deceleration also operate according to the
acceleration time and deceleration time that FREQ instruction designates.
5. Available to lock the current operating frequency by controlling M1052.
6. Available to execute temporarily stop (halt) by controlling M1044, the deceleration method is
according to the deceleration setting.
7. Available to execute quick stop by controlling M1042, the deceleration method will decelerate
as soon as possible on the premise that no error occurs. (An error may occur if the load is too
large)
8. The authority to control is M1040 (Servo ON) > M1042 (Quick stop) > M1044 (Halt) > M1052
(LOCK)
