Actual Dec time =
V/F Maximum output frequency = parameter 01-02 when programmable V/F is selected by 01-
Motor rated output frequency is set by parameter 02-06.
00=【7】.
V/F Maximum output frequency = 50.00 hz or 60.00 hz when preset V/F patterns are selected.
01- 00≠【7】.
Examples is in V/F mode:
01-00 ≠ 7, 01-02 =50Hz, 05-02=10Hz (preset speed 1),
05-19 = 5s (Accel time), 05-20=20s (Decel time)
( ������������������������ �������������������� 1 ������������ ���� �������� �������������������� ���� ���� ���� ���� ) =
( ������������������������ �������������������� 1 ������������ ���� �������� �������������������� ���� ���� ���� ���� ) =
Multi speed run/stop cycles with Individual Accel/Decel times. 05-00=【1】
Two modes are shown below:
Mode1 = On/Off run command
Mode2= Continuous run command
Mode1 Example: 00- 02=【1】(External Run/Stop Control).
00- 04=【1】(Operation Mode:Run/stop-forward/reverse).

When the run command is On/Off, acceleration and deceleration times for each cycle can be
calculated as below: time unit is in seconds.
Time of Decel 1 or 2 x Preset Frequency
S1: 03- 00=【0】(RUN/STOP );
S2: 03- 01=【1】(Forward/Reverse);
S3: 03- 02=【2】(Preset speed 1);
S4: 03- 03=【3】(Preset speed 2);
S5: 03- 04=【4】(Preset speed 4);
